If the resistance of an electrical circuit is 15ohms and the voltage is 9 volts, what is the current

Suppose a comet has an orbital period of 309.1 years around the sun. what is it’s average distance from the sun?

Often called simply "velocity," this is the velocity of an object at a particular moment in time.

The space between two 15-in.-long concentric cylinders is filled with glycerin (viscosity = 8.5 × 10-3 lb·s/ft2). the inner cylinder has a radius of 1 in. and the gap width between cylinders is 0.1 in. determine (a) the torque and (b) the power required to rotate the inner cylinder at 180 rev/min. the outer cylinder is fixed. assume the velocity distribution in the gap to be linear.
