A 76 kg surfer travels through the barrel of a wave at 11 m/s. What is his kinetic energy (KE) in Joules?

A30 kg weight lies on top of a massless piston of area a = 0.01 m2 the exterior air is at a (constant) p =1 atm and t = 27 c. the interior gas is 0.4 moles of (ideal) n2 and it has initial temperature 27.00 degrees c. 1. what is the initial pressure in the interior? a. 29.4 kpa b. 130.7 kpa c. 101.3 kpa the next three questions concern what happens when an amount of heat q is slowly added to the interior, raising the piston by 1 mm and raising the interior temperature to 27.40 c

Give an example in which the electrical energy changes to light energy

The built in flash in a compact camera is usally capable of giving correct exsposure for distance up to how many meters?
