An electric kitchen range has a total wall area of 1.40 m2 and is insulted with a layer of fiber glass that has a temperature of 175 oC and its outside surface is 35 oC. The fiber glass has a thermal conductivity of 0.040 Wm-1K-1. Calculate the rate of flow of heat through the insulation, assuming the fibre as a flat slab of area of 1.40 m2.​

Using the work energy theorem. what is the velocity of a 850kg car after starting at rest when 13,000j of work is done to it.

Astudent is performing an experiment comparing sound and light waves. the student gathers the following data. what conclusion does the student most likely make based on this data? light waves always travel the same speed; however, the speed of sound is determined by the medium that it travels through. all sound waves always have the same energy, so the temperature of the medium does not affect wave speed. light needs to vibrate particles, so it travels fastest in tightly packed solids, while sound does not need a medium, so it travels fastest in a gas. tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.

Aperson standing in a canoe exerts a force of 700 n to throw an anchor over the side. find the acceleration of the canoe if the total mass of the canoe and the person is 100 kg?
