Did you guys know that saying ''R" is disrespectful and offensive? Ill explain: Because “R” is used to mock people on the autism spectrum, supposedly mimicking a noise that someone on the spectrum might make

Write short note on the following ; collision theory, rotation angle and angular velocity, centripetal acceleration, coriolis force, and newton's law of gravitation.

An electron and a proton have the same kinetic energy upon entering a region of constant magnetic field and their velocity vectors are perpendicular to the magnetic field. suppose the magnetic field is strong enough to allow the particles to circle in the field. note: you'll need to look up the masses for an electron and proton. 1) what is the ratio of the radii of their circular paths rp/re?

What is relative velocity? in which condition is relative velocity known by adding the velocity of the first body and that of the second body
