An object is undergoing uniform circular motion. which of the following changes would increase the period of the motion? i. increase the radius of the circular motion. ii. decrease the radius of the circular motion. iii. increase the speed of the object. iv. decrease the speed of the object.

What are the similarities & differences between a thermistor and a light dependent resistor in physics?

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.

Give an example of a collision in real life. use the law of conservation of energy to describe the transfer of momentum. be sure and discuss the momentum before and after the collision occurs.
