Two point charges having charge values of 9.2 E -6 C and 3.5 E -6 C, respectively, are separated by 3 E -2 m. What is the absolute value of the mutual force between them

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

Name two kinds of practical electric pumps.

Acar's position in relation to time is plotted on the graph. what is the car's average velocity for segment c? a) -4 m/s b) -0.25 m/s c) 0.25 m/s d) 4 m/s
