A force of 4 N is attracting two steel balls of a magnitude of each charge of 7.1 x 10-6 C. What is the initial distance between the steel balls in meters? What is the initial distance between the steel balls in cm? Since the steel balls are attracting each other, what are their charges?

What is the measurement of how fast an object moves relative to a reference point?

Nitrogen (n2) undergoes an internally reversible process from 6 bar, 247°c during which pν1.2 = constant. the initial volume is 0.1 m3 and the work for the process is 121.14 kj. assuming ideal gas behavior, and neglecting kinetic and potential energy effects, determine heat transfer, in kj, and the entropy change, in kj/s. show the process on a t-s diagram.

If jason ii needs 15 kw of power at 300 volts to operate, what amperage of current must flow through the cable?
