Astring is wrapped tightly around a fixed pulley that has a moment of inertia of 0.0352 kgm2 and a radius of 12.5 cm. the string is pulled away with a constant force of 5 n. as the string unwinds the pulley begins to rotate. what is the speed of the string after it has unwound 1.25 m

Agas is contained in a vertical, frictionless piston–cylinder device. the piston has a mass of 3.2 kg and a cross-sectional area of 35 cm2. a compressed spring above the piston exerts a force of 190 n on the piston. if the atmospheric pressure is 95 kpa, determine the pressure inside the cylinder.

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