Aman pushes a 60.8 kg crate across a rough surface with an applied force of 125 n and at a constant speed.

what is the magnitude of the force normal acting on the box?

convex lenses are thicker at the middle. rays of light that pass through the lens are brought closer together (they converge). a convex lens is a converging lens. when parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus.

heat the gas and measure the pressure

the ima (higher than 1m) will be greater than the ima with the height of 1m.
