There all diffrent shapes and sizes so its kind of hard to answer you question
Answer:
Hey Queen Messy here!
I believe it is true.
Weight is the way we usually describe what the scales tell us, but our weight is actually something different.
"When you get on the scale and it tells you that you weigh 50 kilograms, that isn't your weight. That's actually your mass", says Dr Nicole Bell from the University of Melbourne.
"In everyday speech weight and mass are used interchangeably, but weight is a figure arrived at by multiplying mass by gravitational acceleration".
Physicists use Newton's 2nd law (F = ma) to describe the forces acting upon an object moving through space, where force is equal to mass times acceleration.
"In the case of weight, we can describe the force as W = mg", says Bell. "That is weight is equal to mass times gravitational acceleration.
Weight is not measured in kilograms, but in Newtons.
Explanation:
Deacreasing the mass of one objects.
Increasing the mass of one of the objects.
Deacreasing the distance between the objects. (hope this helps)
Answer:
Yes
Explanation:
p = momentum of photon
E = energy of photon
c = velocity of light
Units of p = kg m /s
Units of E = kg m^2 / s^2
Units of E / p = {kg m^2 / s^2} / {kg m /s} = m/s
It is the unit of speed, so by the division of energy to the momentum, we get the speed. yes it is correct.
