Answer: force from sun to mars = , force from mars to sun =
Explanation: The force of attraction or repulsion between 2 object ( in this case the sun and mars ) in space is given by newton's law of gravitation which is given mathematically below as
where
G = gravitational constant, = mass of mars, = mass of sun
the mars also exerts the same magnitude of force above on the sun but in the opposite direction, thus the force mars exerts on the sun is
Answer:
0.04
Explanation:
Fraction of power converted to sound = 80% = 0.08
Fraction incident upon each eardrum onstage = 0.08/2 = 0.04

Answer:
137.2J
Explanation:
Ep= mgh
Given,
and we know, g = 9.81 N/kg
Ep= 2 × 9.81 × 7
Ep= 137.2J
