While a kettle boils, 0.018kg of water changes to steam
calculate the amount of energy required for this change
specific latent heat of vaporisation of water = 2.3 x 1j/kg

After a big snowfall, you take your favorite rocket-powered sled out to a wide field. the field is 195 m across, and you know that your sled accelerates at a rate of 3.65 m/s2 when the rocket is on. how much time will it take the sled to cross the field starting from rest, assuming the rocket is on the whole time?

Use the information presented in the graph to answer the questions. which segments show acceleration? which segment indicates that the object is slowing down? what is the velocity of segment b? what is the acceleration of segment b?

The least penetrating form of radiation is
