A rope horizontally pulls a massive object lying on a surface with friction with a constant velocity. What describes the force on the rope?

What is the coefficient of kinetic friction μk between the block and the tabletop?

This is the number of complete movements of a wave per second.

Pressure is a measure of force per unit area or p=f/ap=f/a. a student is checking the amount of pressure their car exerts upon the road. the car weighs 22 tons ( us short ton ). the student finds the dimensions of each tire's footprint on the road is 12.5 cm x 16.5 cm. in pounds per square inch (psi), what is the total pressure the car exerts upon the road?
