The light from the sun is reflected by the moon, we see the part of the moon that the sun shines on.The change in the phases are created from the rotation of the moon around earth.We see a full moon when the sun is opposite of the moon. The side the sun shines on the moon is what we see.
There is no displacement. The frog is back where it began.
Answer: The recoil speed is - 8.9604.
m/s.
Explanation: According to the Third Law of Newton, every action has an oppsite and equal reaction, and the Second Law of Newton, Force=mass·acceleration. Acceleration is a variation in velocity by any given time, so Force = mass·velocity·time.
Combining the two laws, there is : m1·v1 = - m2·v2. This is the Law of Conservation of Momentum.
Substituting and calculating:
v2 = - (
) · v1
v2 = -
· 5.24.
v2 = - 8.9604.
The recoil speed of the thorium nucleus is - 8.9604.
m/s.
Hello! Your answer would be D. Interference
This is because interference causes vibration!!!
The total work done is equal to 134 J.
<h3>Work</h3>
The work formula is characterized as the multiplication of the force performed and the distance in which the movement was performed, so that:

Thus, it is enough to calculate the value of the work in each movement and add to find the total work, so that:


So, the total work done is equal to 134 J.
