Question

Problem Eleven. A hollow sphere with rotational inertia 1 = (2/3)MR2 is moving with speed v down an incline of angle 0 toward a spring with spring constant k. After traveling a distance d down the incline with no slipping, the sphere makes contact with the spring and compresses it a distance x before it comes momentarily to rest. Find the distance d in terms of the other quantities given. (21) 19.) (A) d=- 2Mg sin kx²-Mv² +x (B) d= 2Mg sin kx²+Mv² +x kx²-Mv² (C) d=- -x (D) d= 2Mg sin 2Mg cos kx²-Mv² 2Mg sin -x (E) d= kx²-Mv²

1. A light bulb operates at a temperature of 4,300 K and has an emissivity of 0.600 and a surface area of 5.50 mm². How long would the light bulb have to shine on a 2.00 g piece of ice that is at -30.0°C in order to turn the ice into steam at 120°C? Assume all the energy radiated by the light bulb is absorbed by the ice while it becomes liquid and eventually steam. Give an answer in seconds. The following are specific heats for ice, water, and steam. Cice = 2,090 ***C kg kg."C Cwater = 4,186 C Csteam = 2,010 C kg"C The following are latent heats for water.
