A2.10 kg textbook rests on a frictionless, horizontal surface. a cord attached to the book passes over a pulley whose diameter is 0.170 m, to a hanging book with mass 3.00 kg. the system is released from rest, and the books are observed to move 1.20 m in 0.900 s.
(a) what is the tension in each part of the cord?
(b) what is the moment of inertia of the pulley about its rotation axis?

Will give brainliest! which statement best describes the similarities between fundamental forces? electromagnetic and strong nuclear forces influence the interaction between charged particles within an atom. gravitational and magnetic forces are both types of charges that occur in nature. nuclear and magnetic forces are both related to mass and weight. strong nuclear force is most like electrical force because they are both related to distance.

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.
