Answer: 15 m/s2
Explanation: I hope this helps or right because I learned this a few months ago
The hypothesis is that around four and a half billion years ago, a mars-sized planetary object collided with the forming earth, merging the two masses at the expense of a massive amount of ejecta. This particulate ejecta, influenced by the local gravity, attracted together and formed the moon, locked tidally to the earth.
Answer:
The relationship of the speed of sound, its frequency, and wavelength is the same as for all waves: vw = fλ, where vw is the speed of sound, f is its frequency, and λ is its wavelength. ... The frequency is the same as that of the source and is the number of waves that pass a point per unit time.

False.
The mass of a softball is approximately 200 g (0.2 kg), while the knees are located approximately at 30 cm (0.3 m) from the ground. It means that the gravitational potential energy of the ball when it is dropped is
This corresponds to the total mechanical energy of the ball at the moment it is dropped, because there is no kinetic energy (the ball starts from rest). Then the ball is dropped, and just before it hits the ground, all this energy is converted into kinetic energy: but energy cannot be created, so its final kinetic energy cannot be greater than 0.6 J.
Answer:
It will take. the same distance up as before, but take a longer time
