Apiston-cylinder system contains of 3 kg of saturated mixture of water at 160 kpa. initially, water is in liquid phase. heat is now transferred to the water and the piston, which is at the stop, start moving when the pressure reaches 500 kpa. heat transfer continues until the total volume increases by %20. determine, a. the initial and final temperature, b. the mass of liquid when the piston first starts moving, and c. the work done during this proce

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 710 n/m. it is initially at rest on an inclined plane that is at an angle of θ = 23° with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is μk = 0.19. in the initial position, where the spring is compressed by a distance of d = 0.16 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. a) what is the block's initial mechanical energy? b) if the spring pushes the block up the incline, what distance, l, in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.

The most important difference between a wedge and an inclined plane is a. their size b. their shape c. how they are used d. what they are made of

When a light bulb shines, it gives off light energy and energy. a. heat b. potential c. chemical d. electrical
