You and some friends are loading a moving truck. You get a heavy box to the top of the loading ramp which is angled at 15 degrees from the ground. The high end (top) of the ramp is 12.5 m above the ground. You accidently make the assumption that your friends had the box secure and stop pushing. The box begins to move down the ramp. How long does it take to reach the bottom of the ramp?

The key to stability is feedback between the reservoir and the fluxes into and/or out of the reservoir. assume that the rate of outflow from a reservoir depends on the size of the reservoir according to the following relationship: outflow rate= k x (size of reservoir), where k is a constant. a reservoir of water has a volume of 5000 liters, and the rate of outflow at steady state is 25 liters per minute. what is k? (give both the numerical value and its units.) what is the residence time? what is the relationship between k and the residence time?

In science and physics what is the standard unit of measure for speed?

What part of the ear is names after tools, such as the hammer and the anvil?
