D) The speed of a wave slows as it travels at different speed in different media.
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".
Answer:
a.
b.
Explanation:
We are given that
a.We have to find the angle
b. We have to find the speed 
According to law of conservation of momentum
32 degrees Fahrenheit
And
0 degrees Celsius
