On a whim, you are trying to stand in a cart attached to a strong spring. The spring is compressed and then released, and you oscillate back and forth, trying to maintain your balance. There is a sand bag in the cart.
At the instant you pass through the equilibrium (x=0) location of the spring, you drop the sandbag onto the ground, out of the cart.
Question: If you drop the sand bag out of the cart right at the equibrium location, what effect will that have on the amplitude of your oscillation? (choose correct choice):
a.) The amplitude of oscillation will increase.
b.) The amplitude of oscillation will decrease.
c.) There will be no effect on the amplitude.
On dropping the sandbag the amplitude of vibrations will decrease.
what is amplitude?when compared to its equilibrium position, the displacements or distance traveled by a spot on a vibrating body or wave.
Why amplitude will decrease on dropping the sand bag?The cart-spring mechanism loses energy when the sandbag is dropped. Because of this, the amplitude cannot be constant.
The system would only be able to gain energy if the amplitude increased. The sandbag is dropped, yet there is no gain in energy.
The sandbag possesses kinetic energy at equilibrium, which escapes the system containing the sandbag. Since the amplitude and system energy are inversely proportional (E=1/2(k)A2), a decrease in system energy must result in a decrease in the motion's amplitude.
Thus, the amplitude is reduced.

In the problem, it was stated that "a box of mass m slides at a speed v along a horizontal, smooth table", the word "smooth" allow us to assume that the table is frictionless.
Frictionless surface is a surface with little to almost none friction. Frictionless surface alllows the force acting on any object which makes it difficult fo the object to slide or the friction force is almost zero or negligible. In the real world, there is no such a thing called frictionless surface, artificially the smoothest surface will have some friction at some locations.
Friction force is the force that opposes the sliding movement of an object accross another object or surface. The friction force direction will always be the opposite of the motion of an object. Friction force can be divided into 2 kinds:
Static frictionKinetic frictionStatic friction is the friction force working on an object when an object is not moving. Static friction keeps an object stay still and resists any force working on an object. However, when the force given to an object increase and the object start to move, static friction is no longer working in the system.
Kinetic friction is the friction force working on an object when an object is moving. Kinetic friction allows an object to slow down when the force is released.
Generally, static friction is greater than kinetic friction.

Explanation:
This is Newton's 2nd Law, F = ma. If the mass of an object does not change, a constant net force on the object produces constant acceleration, in the direction of the net force.
what is the acceleration of a falling object that has reached its terminal velocity? group of answer choices the acceleration is g^2. the acceleration is 0. the acceleration is -g. the acceleration is g.
The acceleration of the abject at terminal velocity is zero.
The terminal velocity of an object falling through a fluid is its maximum attainable velocity in the fluid. it is said to occur when the sum of the drag force and the buoyancy is equal to the downward force of gravity acting on the object. At terminal velocity, the object stops accelerating and moves at constant velocity.
When the object has reached its terminal velocity, the gravity which is a downward force is equal to the sum of the buoyancy of the object and the also it drags the force. This makes the acceleration to be zero at terminal velocity.
Therefore, an object at terminal velocity has zero net acceleration.

In the Doppler effect it Is important to distinguish between frequency and speed. speed and velocity: speed and acceleration: distance and displacement
In the Doppler effect, the important things to distinguish between are frequency and velocity (speed).]
Doppler effect is the frequency change of a wave in relation to an observer that is moving relative to the source of the wave. It happens because when the source of the waves is moving towards the observer, each wave crest is emitted in a closer position to the observer than the previous wave. That makes each wave takes less time to reach the observer compared to the previous wave, causing an increase in frequency.
Since the Doppler effect is all about frequency change and a moving object is involved in it, it's important to distinguish between wave frequency and the speed the object is moving in.

water falls without splashing at a rate of 0.260 l/s from a height of 3.80 m into a 0.760-kg bucket on a scale. if the bucket is originally empty, what does the scale read 3.50 s after water starts to accumulate in it?
When bucket is originally empty, then the scale reads after water starts to accumulate in it is T = 18.97 N.
What is net force?The net force is defined as the vector sum of forces acting on a particle or object. The net force is a single force that replaces the effect of the original forces on the motion of particle.
After 3.50 seconds, bucket contains 0.91 L of water, which has mass of 0.760 kg same as the bucket. The total mass m of the bucket and the water is 0.91 + 0.760 = 1.67 kg.
So, the gravitational force F,
As, F = mg = (1.67)(9.81) = 16.738N
There is an additional downward force resulting from the momentum of the water being poured and every second, there is 0.260 L = 0.260 kg of water hitting the bottom of the bucket.
Since water falls without splashing, this implies means we can neglect the height of the water that is already in the bucket, and just say that it has fallen full distance of x = 3.80 m.
After falling that distance, water will reach a velocity of sqrt(2gx) = 8.63 m/s
So, force W will be the change of momentum over time,
We know, W = mv/t
= (0.260 kg) (8.63 m/s) / 1 s

a car traveling along a highway needs a certain amount of force exerted on it to stop it in a certain distance. more stopping force is required when the car has question 40 options: less stopping distance. more momentum. more mass. all of these.
Based on the Second Law of Newton, a car traveling along a highway needs more amount of topping force exerted on it to stop when the car has less stopping distance, more momentum, and more mass (D).
Based on the Second Law of Newton, we know that the acceleration of an object is dependent to its resultant force and mass. The second law of Newton could be formulized as:
∑F = m.a
where:
F = the resultant force
m = the object's mass
a = the object acceleration
On the case, we know that a car is traveling along a highway. The car's stopping force will be dependent on the car's mass and its acceleration.
Let's dig deeper on acceleration part.
As we know, based on the linear motion concept, there are some equations to describe relationship between velocity, acceleration, distance, and time. Those equaations are:
v = u + at
s = ut + 1/2 at²
s = 1/2 (u+v)t
v² = u² + 2as
s = vt - 1/2 at²
where:
v = final velocity
u = tnitial velocity
a = acceleration
t = time
s = distance
If we subtitute one of acceleration equation to the second law of Newton, we will get:
F = m.a
v = u + at
a = (v-u)/t
F = m.(v-u)/t
F = mv - mu
t
Based on the momentum concept, we know that momentum is the result of multiplication between an object's mass and velocity. Hence the sopping force is also affected by the momentum of an object.
If we subtitute another acceleration equation, we will find another equation:
F = m.a
s = ut +1/2at²
a = 2(ut-s)
t²
F = m[2(ut-s)/t²]
This equation shows that the stopping force will also be affected by the distance of an object betweenn its initial position to its final position.

what does special relativity reveal about the speed of light relative to its source? what does special relativity reveal about the speed of light relative to its source? light moves faster if emitted by a source moving in the direction opposite the emission. light moves at the same speed independent of the motion of the source. light moves more slowly if emitted by a source moving in the direction opposite the emission. light moves more slowly if emitted by a source moving in the direction of emission. light moves faster if emitted by a source moving in the direction of emission.
The speed of light relative to its source is light moves at the same speed independent of the motion of the source. Option B.
The Special Theory of Relativity is based on Einstein's discovery that the speed of light does not change as the light source moves. It may seem logical to add the speed of the light source and the speed of the ray to determine the overall speed, but light doesn't work that way.
The speed of light is constant for everything. What Newton, and later Einstein, showed was that there was no underlying frame of reference. All movements are relative.

if the mass of a wheel is increased by a factor of 2 and the radius is increased by a factor of 1.5, by what factor is the moment of inertia increased? model the wheel as a solid disc.
The Moment of inertia is increased by the factor of 3.
Rotational inertia, or moment of inertia, is the rotational equivalent of mass; this is the quantity we want to measure to see how much energy is needed to accelerate the wheel. We can measure the weight of a wheel relatively easily, but it is not necessarily true that the lightest wheel will have the smallest moment of inertia or vice versa. If we have a rigid body rotating with an angular velocity Ω about a fixed axis , each particle in it will have a certain amount of kinetic energy. A particle of mass m with radius r from the axis of rotation moves in a circle with radius r with angular velocity Ω around this axis. So it has a linear velocity v = Ωr and its kinetic energy K is ½ mv2 = ½ mΩ2r2. The total kinetic energy is the sum of the kinetic energies of its particles, and each particle in a solid moves with the same angular velocity Ω (it moves the same number of angular degrees per unit time), but the radius r can be different for different particles. So the total kinetic energy isK = ½ (m1r12 + m2r22 + …)Ω2 = ½ (∑miri2)Ω2
The moment of inertia of the wheel is given as
I = MR2
if M' = 2M and R' = 1.5R

Yes, the eccentric contractions need less, the same, or even more fibers to produce the same force at the same degree of muscular force.
Explain the term eccentric contractions?When a force applied to a muscle exceeds the immediate force produced by muscle itself, an eccentric (lengthening) muscular contraction happens, forcing the muscle-tendon system to lengthen while contracting.
Eccentric contraction happens when tension is produced and the length of the muscle as a whole rises. A biceps curl's lowering phase, for instance, is an eccentric contraction.

The new oscillation frequency is 1.07 rad/sec when the pendulum is rehanged to the rod halfway between the old pivot point and the middle of the rod.
What is the Period of oscillation?
The period of oscillation is the shortest amount of time after which the motion of the particle repeats. The period of oscillation is the length of time it takes for a particle to complete its to-and-fro motion.
What is a pendulum?A body suspended from a fixed point so that it can move back and forth while being pulled by gravity is called a pendulum. A pendulum's whole back-and-forth oscillation has a consistent time interval.
Calculations:
Period of pendulum T = 2 × √I/mgd
Where,
I = moment of inertia
L = length of the pendulum
m = mass
d = distance or L/2
g = acceleration due to gravity.
When pivoted at one end = I = 1/3mL²
When pivoted at other end = f = 1/2π × √mgd/I
f= 1/2π × √(mgL/2)/(1/3 mL²)
f= 1/2π × √ (3g)/(2L) -------------------- (i)
Now when pivoted mid way
I' = mL²/12 + m (L/4)²
I' = mL²/12 + m L²/16
I' = 7mL²/48
Thus here d= L/4
f' = 1/2π × √(mgL/4)/(7/48mL²)
1/2π × √(12g/7L) ----------------------(ii)
Then, f'/I = {1/2π × √(12g/7L)}/{1/2π × √ (3g)/(2L)}
= √ 1.14
~ 1.07 rad/sec.
Hence, the new oscillation frequency is 1.07 rad/sec when the pendulum is rehanged to the rod halfway between the old pivot point and the middle of the rod.

The "pressure" that drives electricity is known as voltage. Higher voltages cause more electricity to flow to an electronic equipment. The voltage is measured in units called volts (V), and it is symbolized by this unit. The circuitry in electronic devices can be harmed by high voltages because they are made to function at specified voltages.
In contrast, a voltage that is too low can also lead to problems since it disables circuits and renders the devices that are constructed around them inoperable. In order to manage electronic devices properly and locate the root causes of troubles when they arise, one needs to have a basic understanding of voltage and how to resolve related problems.

a muon is traveling at 0.4c0.4c relative to a laboratory frame of reference. the speed of the muon is doubled to 0.8c0.8c. part a what happens to the momentum of the muon in the laboratory frame of reference?
When measured in a laboratory frame of reference, the momentum more than doubles to that of the muon.
A muon and an electron are two different particles.Compared to the electron, muons are 200 times heavier. They are intriguing because of their higher mass, but they are also unstable because of it. While muons only last for two microseconds, or two millionths of a second, before decaying, electrons persist for an infinite amount of time.
For what purposes do muons?Nuclear power reactors with damage can be seen inside using muon technology. In order to look into big, thick monuments like the Egyptian pyramids, scientists employ muons in their archeological research.

two objects attract each other with a gravitational force of magnitude 1.02 10-8 n when separated by 20.2 cm. if the total mass of the two objects is 5.06 kg, what is the mass of each?
The mass of each objects are 4.988 kg and 0.01202 kg.
First, its force-mediating boson is immaterial, just as a photon (the electromagnetic force's force-mediating boson) is immaterial. Massless bosons can carry force a long way. Both EM and gravitational forces follow an inverse square law (force is proportional to 1/r^2, where r is the distance between the centers of gravity). In contrast, the strong and weak nuclear forces have boson that carry matter, and their range is extremely short.Second, there is no "repulsive" mode of gravitational force. The electromagnetic force comes in both attractive and repulsive polarities, and since matter is generally charge neutral, the two cancel out almost perfectly at great distances. But gravity is only attractive, so it keeps adding up. As a result, it can reach far.Now the force weakens with increasing distance, meaning it needs more "action time" for any given change in the object's motion to occur. But on interplanetary and even interstellar scales, there is plenty of time for small changes per second to add up.M = -b/(2a) +-√((b/(2a))^2 -c/a)
M = 2.5 +-√(6.25 -0.05997)
M = 2.5 +-2.4879
M = 4.988 kg and 0.01202 kg
