What is the thermal efficiency of this furnace? A race car, moving initially with a speed of A rubber stopper, which has a mass of

The light ray forms an angle of with the normal.

How much force F is needed to press this mass against the spring as shown? What will be the altitude of this orbit? Determine the approximate diameter of the emerging beam. Give us a call today or request a quote! What will be the velocity of this ball when it reaches the ground homfwork

A ray of light traveling in air enters a rectangular glass slab through its one face and emerges out of it through its opposite parallel face. A light ray falls on a square glass slab on horizontal face with incident angle 45degrees.

What will be rdflection GPE of this crate when it reaches the top of the incline? Since all i vectors are in the same direction [parallel to the x axis] they can be added together just like scalars as shown in parts a-d.
