A soccer ball rests on the field at the location x = 5.0 m. Two players run along the same straight line toward the ball. Their equations of motion are as follows: x1 = –8.2 m + (4.5 m/s )t
x2 = –7.3 m + (3.6 m/s )t

What is the location of the players when one passes the other?

Which of the following correctly describes the early view of catastrophism?

Which is the best for showing percentages of different types of cars sold(gas hybrid , electric , other ) in the united states ?

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?
