An object is attached to a vertical ideal massless spring and bobs up and down between the two extreme points a and b. when the kinetic energy of the object is a minimum, the object is located

An air-standard stirling cycle operates with a maximum pressure of 600 psia and a minimum pressure of 10 psia. the maximum volume of the air is 10 times the minimum volume. the temperature during the heat rejection process is 100°f. calculate the specific heat added to and rejected by this cycle, as well as the net specific work produced by the cycle. use constant specific heats at room temperature. the properties of air at room temperature are r

Determine the amount of work done when a crane lifts a 100-n block form 2m above the ground to 6m above the ground

The radius of a sphere is increasing at a rate of 9 cm/ sec. find the radius of the sphere when the volume and the radius of the sphere are increasing at the same numerical rate.
