On the surface of planet x, a body with a mass of 10 kilograms weighs 40. newtons. the magnitude of the acceleration due to gravity on the surface of planet x is

The acceleration due to gravity of the body is 4 ms-2.

We define the weight of an object as the product of the mass of the object and acceleration due to gravity. The value of the acceleration due to gravity varies from place to place in the universe.

From the information presented in the question;

W = mg

m =  10 kilograms

W = 40 newtons

g = W/m

g = 40 newtons/10 kilograms

g = 4 ms-2

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
