The answer is a newton second law
The gravitational force would get stronger because the farther the two masses are separated the more gravitational force will be used to pull them together the closer they are the less gravitational pull is used to pull them together
The movement of a fluid during convection is a circular/oval motion since the fluid at the top sinks and the fluid at the bottom rises.
Hope this helps :)
Yes it is possible. Spectrum of emitted light depends upon the chemical composition of the source. and the way of its excitation. a clear example to us is that of sun.
Explanation:
Average acceleration is change in velocity over time.
a = Δv / Δt
a = (22.0 m/s − (-25.0 m/s)) / 0.00350 s
a = 13,400 m/s²
