Answer:
A
Explanation:
The particles of the medium don't travel along with the wave. and I also just did this question
Answer:
The momentum of the falling apple is transferred to the Earth.
Explanation:
Answer
given,
mass of an object = 5 Kg
mass of the other object = 5.98 x 10²⁴ Kg
radius of earth = 6371 Km = 6.371 x 10⁶ m
comparison between gravitational force between two object and weight of the object.
gravitational force between two objects
F = 49.134 N
weight of the object on the earth surface
F = m g
F = 5 x 9.81
F = 49.05 N
From the above two calculation we can conclude that gravitational force is approximately equal to weight of the body.
