Are there supposed to be multiple choices for this question?
In this question a lot of information's are provided. Among the information's provided one information and that is the time of 4 seconds is not required for calculating the answer. Only the other information's are required.
Mass of the block that is sliding = 5.00 kg
Distance for which the block slides = 10 meters/second
Then we already know that
Momentum = Mass * Distance travelled
= (5 * 10) Kg m/s
= 50 kg m/s
So the magnitude of the blocks momentum is 50 kg m/s. The correct option among all the given options is option "b".
Given what we know, we can confirm that when a light wave is refracted, it changes direction.
<h3>What is refraction?</h3>
Refraction is a term used to explain and describe the change in direction of a light wave as it passes through a medium. This change in direction is caused by the change in speed of the light wave entering a new medium.
Therefore, we can confirm that when a light wave is refracted, it changes direction.

Here's my pick at this:
Entropy (or some form of disorder) will always increase in time.
Thus if you look at snapshots of a system and see that it's entropy is increasing you can tell the flow (or arrow) of time!

Answer:
B) 2 times what it now is
Explanation:
The acceleration due to gravity at the surface of the Earth is given by
where
G is the gravitational constant
M is the mass of the Earth
R is the Earth's radius
In this problem, the mass of the Earth is doubled:
M' = 2M
while the radius remains the same:
R' = R
so the new acceleration due to gravity would be
so, the acceleration due to gravity would become twice the current value.
Note also that the value of g does not depend on the mass of the objects involved.
