Choose the correct alternative. A football player kicks a football from the ground level
with an initial speed of 23.0 m/s. The ball leaves the
ground making an angle of 30.0°with the ground. Find
the distance traveled by the ball before it hits the ground.

The pressure, volume, and temperature of a mole of an ideal gas are related by the equation pv = 8.31t, where p is measured in kilopascals, v in liters, and t in kelvins. use differentials to find the approximate change in the pressure if the volume increases from 14 l to 14.6 l and the temperature decreases from 375 k to 370 k. (round the answer to two decimal places.)

An incident ray through the focal point of a spherical mirror will: reflect through the center of curvature. reflect back through the focal point. reflect parallel to the principle axis. reflect the same direction as the incident ray.
