A) The weight of the orange is 2.4N and B) It takes 1.542s for the orange's momentum to change by 6. 1 kg·m/s.
What is weight?Weight is the measure of the force of gravity on an object. It is a measure of the amount of matter present in an object and is measured in units such as kilograms, pounds, or ounces. Weight is the same no matter where an object is located, as gravity is a universal force. Weight is different than mass, which is the amount of matter in an object regardless of gravity. Mass is measured in kilograms, grams, or other metric units. Weight can be calculated by multiplying an object's mass by the acceleration due to gravity.
(a)
The rate of change of the momentum of any object is equal to the force acting on the object.
The orange is free falling so the force acting on the orange will be equal to to weight of the orange.
Then, the weight of the orange is 2.4N.

two parallel conducting plates are separated by 12.0 cm, and one of them is taken to be at zero volts. (a) what is the magnitude of the electric field strength between them, if the potential 6.0 cm from the zero volt plate is 450 v?
The magnitude of the electric field strength between the two parallel conducting plates is 75 V/cm.
What is magnitude?
The magnitude of a quantity refers to the size or amount of that quantity, regardless of its direction. For example, the magnitude of velocity is the speed at which an object is moving, regardless of the direction it is moving in. Similarly, the magnitude of electric field is the strength of the field, regardless of the direction of the field.
To calculate the electric field strength between the two parallel conducting plates, we can use the formula:
E = V / d
where E is the electric field strength, V is the potential difference, and d is the distance between the plates.
Given that the potential 6.0 cm from the zero volt plate is 450 V, we can use this information to calculate the electric field strength between the plates:
E = 450 V / 6.0 cm = 75 V/cm
So the magnitude of the electric field strength between the two parallel conducting plates is 75 V/cm.

The velocity of the truck after the collision is 5.6 kmph.
What is velocity?The rate at which an object's position changes when observed from a specific point of view and when measured against a specific unit of time is known as its velocity.
The velocity of the truck after the collision can be calculated using the conservation of momentum principle. The principle states that the total momentum of an isolated system remains constant if no external forces act on it.
Momentum is calculated as mass * velocity (p = m * v)
Before the collision, the momentum of the car is m1 * v1 = 400 kg * 72 kmph = 28800 kgkmph
and the momentum of the truck is m2 * v2 = 4000 kg * 9 kmph = 36000 kgkmph
After the collision, the momentum of the car is m1 * v'1 = 400 kg * 18 kmph = 7200 kg*kmph
Now we use the principle of conservation of momentum to find the velocity of the truck after collision.
momentum before collision = momentum after collision
m1 * v1 + m2 * v2 = m1 * v'1 + m2 * v'2
28800 + 36000 = 7200 + m2 * v'2
64800 = 7200 + m2 * v'2
v'2 = (64800 - 7200) / 4000 = 5.6 kmph
Therefore, the velocity of the truck after the collision is 5.6 kmph.

Neglect gravity and assume that the mass also rotates with an angular speed of 3.00 radians/s as shown. (Figure 1) When solving this problem use an inertial coordinate system, as drawn here. (Figure 2)
Assume that, at a certain angular speed ω2, the radius R becomes twice L. Find ω2.
Express your answer in radians per second.
The equation that relates the angular speed ω2 to the spring constant k, the mass M, and the unscratched length L is given by:
ω2 = sqrt(k/M)*2L
What is spring constant ?
The spring constant, also known as the rate or stiffness of the spring, is a measure of the force required to compress or extend a spring by a certain distance. It is defined as the change in force per unit change in length of the spring. The spring constant is usually denoted by the letter k and has units of force per unit length (such as N/m or lbf/in). A spring with a large spring constant will require more force to compress or extend it than one with a smaller spring constant.
Therefore, the angular speed ω2 at which the radius R becomes twice L can be calculated as follows:
ω2 = sqrt(99 N/m / 1.00 kg) * 2 * 0.140 m

As stated above, if a body is moving faster than it is going, then there must be a force acting in the same direction as the sled. Only then can the sled experience constant acceleration and descend at a constant pace.

The mass of the skateboard by conservation of momentum will be 2.84 kg.
In physics, what is momentum?Momentum can be defined as the force behind a body's motion.
Momentum is measured by "mass velocity" since it depends on both the speed and the direction of the body's motion. Since velocity is a vector and mass is a scalar, momentum is a vector quantity.
skateboard mass is 2.84 kg.
m1 = student mass = 45.5 kg
m2= skateboard Mass
u = student Velocity = 4.25 m/s
v = student and skateboard velocity = 4 m/s
As momentum is conserved we have
m1*u=m1*v+m2*v
m2=(m1u-m1v)/v
m2=(45.5*4.25-45.5*4)/4
m2=2.84 kg

A bat emits a series of high-frequency sound pulses as it approaches a moth. The pulses are approximately 70.0 ms apart and each is about 3.0 ms long. How far away can the moth be detected by the bat, so that the echo from one chirp returns before the next chirp is emitted?
Answer:
The moth can be detected by the bat when it is about 21 meters away.
Explanation:
This is because the sound waves travel at about 340 meters per second, so it takes about 70 milliseconds for the sound waves to travel from the bat to the moth and back again.
how thick is the oil? suppose that the density of oil is 900 kg/m3.
The oil is 1 meter thick if the density of oil is 900 kg/m³ and it is kept in a cube shape container of 1 m³ volume.
The density of a substance is defined as the mass contained by the unit volume of the substance. In other words, density is the ratio of the mass and volume of a substance.
Density(d) = Mass(m)/volume(V)
Its SI unit is kg/m³.
If the density of oil is 900 kg/m³. And the volume of cube shaped container is 1 m³. V = 1 × 1 × 1 m³
So the depth would be 1 m³.
