Identify the forces acting on the cars and explain why the cars do not slide down the hill

A 0.153 kg glider is moving to the right on a frictionless, horizontal air track with a speed of 0.700 m/s. It has a head-on collision with a 0.308 kg glider that is moving to the left with a speed of 2.16 m/s. Suppose the collision is elastic.

The magnetic quantum number of an electron (m) designates the: electron's main energy level electron's direction of spin orientation in space of the orbital (electron cloud) overall shape of the orbital (electron cloud)

A force of 70n is applied to a 7kg block that was at rest. the surface is flat and frictionless. how far did the block travel in 10s

Which best blocks X-ray particles and can therefore be observed more closely through the use of this technology?

A light ray travels inside a horizontal plate of glass, striking its upper surface at an angle of incidence of 50°. This ray is totally internally reflected at the glass-air boundary. A liquid is then poured on top of the glass.
