Answer:
The platform move before coming to rest again 0.045 m far
Explanation:
Given
Ball is in motion
M (Platform mass + 2 people mass)
V (recoil velocity of the platform)
m (ball mass)
v (velocity ball)
MV + mv = 0
Distance of the platform movement is
t (time that the ball is in the air)
x = Vt
t = 
Knowing the platform and the ball are moving while the ball is in the air
x = 
Also knowing that

This way,
x =
= 
The minus sign means the displacement of the platform is in opposite direction to the displacement of the ball.
Answer:
When a sound source moves faster than the speed of sound, a shock wave is produced as the sound waves interfere. A sonic boom is the intense sound that occurs as the shock wave moves along the ground.
More importantly, all of the energy gets concentrated into a very small distance this is called a shock wave. In this case, the observer does not hear the approaching source at all until the shock wave hits with all of the energy in the wave. For sound waves, this can cause a very loud noise, called a sonic boom.
Sonic booms produced by aircraft flying supersonic at altitudes of less than 100 feet, creating between 20 and 144 pounds overpressure, have been experienced by humans without injury. Damage to eardrums can be expected when overpres- sures reach 720 pounds

Answer:
Temperature on Jupiter and Saturn are too high for methane to condense.
Explanation:
However, methane can condense on Uranus and Neptune because they are farther from the sun and hence colder.
