a stone is dropped from the top of a cliff. the splash it makes when striking the water below is heard 5.0 s later. How high is the cliff?
48.7 m
When a stone is dropped from a cliff, the stone accelerates downwards due to gravity. We investigate the displacement-time using Newton's Second Law-based kinematic equations. When the stone hits the water surface, sound waves travel the same vertical displacement as the stone to reach the ear of the observer. The motion of sound is a constant-speed motion.
Write an equation for the time it takes for the stone to hit water, PLUS the time for the sound of the splash to come bace. You know the total time; solve for the height, H. Use a suitable speed of sound, such as 340 m/s; you would need to assume a temperature for a more accurate value of the sound speed.
5(seconds) = H/340 + sqrt (2H/g)
[5- (H/340)]^2 = H/4.9
10-(2H/340) = H/4.9
10-0.0058H = H/4.9
H +0.0058H = 10 X 4.9

Center of mass of an object:
The centroid of a mass distribution in space (also called the equilibrium point) is the unique point where the weighted relative positions of the distribution masses sum to zero. This is the point where force can be applied to produce linear acceleration without angular acceleration. Mechanics calculations are often simplified when formulated in terms of the center of gravity. This is a virtual point at which the entire mass of the object can be assumed concentrated in order to visualize its motion. In other words, the center of mass is the particle equivalent of a particular object for which Newton's laws of motion apply.

0.12kg of mass, must be added to the object to change the period to 1.8 s.
What is the period?
The period is the amount of time needed for a simple pendulum to swing back and forth (backwards). Seconds (s) are the SI unit of time. A simple pendulum completes one cycle when it swings back and forth.
What is mass?
The amount of matter in a particle or object is represented by its mass, a dimensionless quantity. In the International System, the kilogram serves as the primary unit of mass.
Calculations:
Given
mass suspended from string M = 0.46kg
Oscillating time T = 1.6sec
To find (M') Mass added to change oscillating time to T' = 1.8sec
we know that:
T = 2π/ω
ω = √ (K/M)
T = 2π √ (K/M)
T = 2π × √ (M/K)
1.6 = 2 × 3.14 × √ (0.46) /K
1.6/6.28 = √ (0.46) /K
0.254 = √ (0.46) /K
Sq. In both sides
(0.254) ² = {√ (0.46) /K}²
0.645 = 0.46 /K
K= 7.13N/m
Now, for time T'
T' = 2π × √ (M'/K)
1.8 = 2 × 3.14 × √(M' /7.13)
1.8/6.28 = √(M' /7.13)
0.286 = √(M' /7.13)
Sq. In both sides
(0.286)²= √(M' /7.13)²
0.0817 = M' /7.13
M'= 0.0817 × 7.13
M' = 0.58kg
To find the added mass
=M' - M
=(0.58 - 0.46) kg

How to calculate the friction force when a body travels through the loop (like in a roaller-coaster) at some point between the top and the bottom?????
Answer:
I think Fgrav=mg
Explanation:
The magnitude of the force acting on the roller coaster car (or passenger) can be calculated using the formula FGRAV=m.g, where the acceleration due to gravity is represented by g (where g=9.8 m/s2).
The magnitude of the normal force depends on three factors—
the speed of the car, the radius of the loop, and the mass of the rider.in which of the following directions would the pressure exerted by a liquid increase? check all that apply. in which of the following directions would the pressure exerted by a liquid increase?check all that apply. going up from the bottom of the container toward the surface. going from the surface towards the bottom of the container. going from the left to right side of the container but maintaining the same depth below the surface.
It fluctuates with depth, which makes it complex. Imagine that the container is just a cylinder and that the pressure is the result of a spring pressing on it from the top.
Why is pressure so crucial?The concept of pressure is crucial to fluid mechanics and is utilized in the ideal gas law to characterize a gas's energy, among many other physical applications.
What causes us to feel pressure?When you stress about not meeting your standards or those of other people, you feel pressure. Additionally, you could experience it when circumstances are beyond your control and you lack the time or resources to do the tasks that are expected of you.

General Questions: In a collision between a huge SUV and a small hybrid car, the SUV exerts a larger force on the hybrid than the hybrid exerts on the SUV. A True O B. False C. It depends on whether the collision is a head-on collision or a rear-end collision. D. It depends on which car moves faster
'In a collision between a huge SUV and a small hybrid car, the SUV exerts a larger force on the hybrid than the hybrid exerts on the SUV' is false.
Every action has an equal and opposite response, according to Newton's third law of motion.
The above law says that, forces on both the vehicles are equal and opposite.
So, the force exerted by a huge SUV and a small hybrid car are the same. And SUV does not exert a larger force as it is huge.
Impact on both the vehicles is also same as the impulse is nothing but the force multiplied by the time of contact. The time of contact is same for both vehicles.
Thus, the above statement is false.

If the speed of every atom in a monatomic ideal gas were doubled, by what factor would the Kelvin temperature of the gas be multiplied?
a) 4
b)2
c)1
d) 1/2
e) 1/4
If the given speed of any atom in a monatomic state of an ideal gas were doubled, then by using four factor we would multiplied the Kelvin present temperature of the gas. Option (a) is correct.
We recollect a monatomic best fueloline having debris of mass m that don't engage and whose middle of mass stays at rest. For a monatomic best fueloline (which include helium, neon, or argon), the most effective contribution to the strength comes from translational kinetic strength. The common translational kinetic strength of a unmarried atom relies upon most effective at the fueloline temperature and is given through the equation: Kavg = 3/2 kt.
These are helium, neon, argon, krypton, xenon, and radon. Noble gases have a complete outer valence shell making them as an alternative non-reactive species. Many gases which include nitrogen, oxygen, hydrogen, noble gases, a few heavier gases like carbon dioxide and combinations which include air, may be dealt with as best gases inside affordable tolerances over a significant parameter variety round widespread temperature and pressure.
We know that,
K.E = (1/2) m*[tex]V^{2}[/tex]
