Abaseball leaves the bat with a speed of 40 m/s at an angle of 35 degrees. a 12m tall fence is placed 130 m from the point the ball was struck. assuming the batter hit the ball 1m above ground level, does the ball go over the fence? if not, how does the ball hit the fence? if yes, how far beyond the fence does the ball land?

Power can be defined as a. the distance over which work was done. b. how much work can be done in a given time. c. all the work in an given area. d. the energy required to do work.

Acylinder with a movable piston contains 11.7 moles of a monatomic ideal gas at a pressure of 1.32×10^5 pa. the gas is initially at a temperature of 300 k. an electric heater adds 43200 j of energy into the gas while the piston moves in such a way that the pressure remains constant. cp=20.79 j k^−1 mol^−1 for a monatomic ideal gas, and that the number of gas molecules is equal to avogadro's number (6.022×10^23) times the number of moles of the gas. (a) what is the temperature of the gas after the energy is added? (b) what is the change in volume of the gas? (c) how much work is done by the gas during this process?

What is a subatomic particle with a negative charge and very little mass?
