Answer:
40X
Explanation:
M=F/f
M=800/20 ( the units cancel each other )
M=40X.
The mass would stay the same, but the weight would be only 16.5%.
Explanation:
Mass is the amount of "matter" in an object, which stays the same everywhere. Weight is the force acting on an object by gravity, which changes depending on nearby bodies. In this case, weight on the moon is 16.5% of that on Earth.
The answer is Stay In Place
As per Newton's II law we know that
here F = force applied
m = mass of object = 2 kg
a = acceleration = 2 m/s^2
now as per above formula we will have
so here applied force on the ball will be 4 N
Size and Mass of the Nucleus
Electrons have virtually no mass, but protons and neutrons have a lot of mass for their size. As a result, the nucleus has virtually all the mass of an atom. Given its great mass and tiny size, the nucleus is very dense.
