This is a matter of thought, so the father is probably more likely to slow down faster because the weighs more and gravity pulls him down to the friction of the ice more potently Thant the child. So, the father.
Coulombs is the correct answer.
The tail consists of gas and dust that can extend hundreds of millions of kilometers away from the coma. Most comets actually have 2 tails: a plasma tail made of ionizedgas, and a dust tail made of small solidparticles. Comet tails point away from the Sun.
Answer:
A) motion parallax
Explanation:
Motion parallax is a visual perception while we are in motion with respect to our surrounding in which the surroundings objects nearer to our eyes appear to move or pass at a faster pace than the objects farther to our eyes during the motion.
This can also be understood as the angular displacement of the objects while our motion. The objects nearer to our eyes have a rapid change in the angular position than the objects far away from us.
Kinetic energy = 1/2 mv²
so, you will have to do it for every single one of them if you want steps.
Kinetic Energy = For A, 202500J
For B, 90000J
For C, 168750J
For D, 75000J
From the above we an say that kinetic energy is highest in option A.
In case, there are no steps needed, just by the values we are able to understand the answer as in Option A, eventhough the mass is the same, higher the velocity or speed, higher the kinetic energy
