Se realiza un trabajo rotacional de 832 J sobre una rueda cuyo radio es de 0.6m, al aplicarle una fuerza cuya magnitud es de 84 N, durante 0.4 s. Calcula: a) La magnitud del desplazamiento angular, b) La potencia rotacional.

How does an observation about an object differ from an inference about that object

Auniform crate c with mass mc is being transported to the left by a forklift with a constant speed v1. what is the magnitude of the angular momentum of the crate about point a, that is, the point of contact between the front tire of the forklift and the ground

The protons in a nucleus are approximately 2 ✕ 10^−15 m apart. consider the case where the protons are a distance d = 1.93 ✕ 10^−15 m apart. calculate the magnitude of the electric force (in n) between two protons at this distance.
