Does the partially elastic collision transfer (more, less, or the same) momentum to the catcher than the completely inelastic collision? Explain.
Answer:
momentum is a vector, KE is scalar. Bodies moving in opposite directions have offsetting momentum, but the KE does not offset.

an elevator suspended by a vertical cable is moving downward but slowing down. the tension in the cable must be:
Answer:
F = M a is the vector equation involved
F = T - M g are the forces acting on the elevator (scalar equation)
T - M g = M a
T = M (a + g) remember this a scalar
If a is slowing down then it must have a positive acceleration upwards
Therefor the tension in the cable must be greater than zero
When the tension increases to M g, a has increased to zero
For a to be zero, no acceleration, T = M g
A grandfather clock keeps time using a pendulum. Which will be true of the clock if the pendulum is shortened? Question 10 options:
It will run slow.
It will run fast.
It will keep the same time.
It will depend on the bob’s mass.
Answer: The period of the pendulum is shorter if the pendulum itself is shortened.
Explanation: i did "It will depend on the bob’s mass". and got it wrong so it's not that one haha

if you throw a football straight up with a velocity of 20m/s, what is its velocity when you catch it ?
Answer:
20 m/s
Explanation:
When we throw a football straight up it comes back with the same velocity.
which state of matter has the greatest amount of kinetic energy?
Answer:
A pure substance in the gaseous state contains more energy than in the liquid state, which in turn contains more energy than in the solid state. Particles has the highest kinetic energy when they are in the gaseous state.

a body dropped from a height reaches a velocity of 13m/s just before touching the ground. What is the initial height of the ball and the time of height
Hi there!
We can use the following (derived) equation to solve for the final velocity given height:
vf = √2gh
We can rearrange to solve for height:
vf² = 2gh
vf²/2g = h
Plug in the given values (g = 9.81 m/s²)
(13)²/2(9.81) = 8.614 m
We can calculate time using the equation:
vf = vi + at, where:
vi = initial velocity (since dropped from rest, = 0 m/s)
a = acceleration (in this instance, due to gravity)
Plug in values:
13 = at
13/a = t
13/9.81 = 1.325 sec

This graph shows how the potential energy of a reaction system changes
over time. Which statement is true for this system?
B
Potential energy
С
Reaction progress
O A. The potential energy of the reactants is greater than the potential
energy of the products
OB. The height of the curve at point A represents the activation energy
O C. The height of the curve at point B represents the activation energy.
O D. The potential energy of the products is greater than the potential
energy of the reactants.
The potential energy of the reactants is greater than the potential energy of the products.
What is potential energy of reaction?Potential energy of a reaction is the stored energy that helps in breaking the bond of a compound during a chemical reaction.
The bonds present in the reactants in the reaction mixture split in the presence of the activation energy to release energy and form the product.
Thus,, option A. The potential energy of the reactants is greater than the potential energy of the products.

Which of the following best describes why longitudinal waves cannot travel in space?
Answer:
A longitudinal wave travels by displacement of material objects.
Air (for instance) particles transmit waves by their oscillation
Space has no material particles to transmit these waves.

Can someone please give me the answers to this? ... please ...
Answer:
See below:
Explanation:
Motion is what makes something move, there are different types and different ways to make motion, motion also comes with forces.
To figure out the motion type, we can simply see the wording of the sentence:
1) Air Resistance is the motion of air, it would be pushing up to stop the fall a bit.
2) We can neglect the resistance by being straight so we have to deal with less of it.
3) This motion is not in motion as nothing happened/happening.
4) This is friction as the friction of the ground and turning the car is slowing it down.
5) The motion is going in any direction as it depends on the start of the asteroid and its starting angle.
6) If its not moving; there is no motion.
7) We can neglect it by going on a 0 degree slope.
8) We simply have to do nothing as its already a law and will happen naturally.
9) The motion is basic motion with some friction due to its scenario.
