A6.0 c charge is placed at the origin and a second charge is placed on the x-axis at x 0.3m. if the resulting electric force on the second charge is 5.4 n in the positive x-direction, what is the value of its charge?

The motor m applies a time-varying force of f (200 t) n, where t is in seconds. box b with mass 200 kg starts from rest, and the coefficients of kinetic and static friction are 0.2 and us 0.3 the acceleration due to gravity is g 9.8 m/s2 b 300 a) find the time ' when the box starts to move. b) calculate the speed of the crate at 3 s c) calculate the power delivered by the motor at t 3 s

70 give a real life example showing how sensory neurons work with the motor neurons

As the distance from a magnet increases, what happens to the magnet force?
