In a polar coordinate system, the velocity vector can be written as . The term theta with dot on top is called angular velocity transverse velocity radial velocity angular acceleration

Free runners jump long distances and land on the ground or a wall. how do they apply newton’s second law to lessen the force of impact?

Nitrogen (n2) undergoes an internally reversible process from 6 bar, 247°c during which pν1.2 = constant. the initial volume is 0.1 m3 and the work for the process is 121.14 kj. assuming ideal gas behavior, and neglecting kinetic and potential energy effects, determine heat transfer, in kj, and the entropy change, in kj/s. show the process on a t-s diagram.

How do you know how many valence electrons an atom has?
