Explain how speed and acceleration are involved in a space shuttle launch. Describe how to make a Density Column, what the different layers mean and how to determine the density of a metal screw.

thank you if you help <33

Spend time observing or thinking about events that involve matter and energy. which events can you explain? which events can’t you explain?

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.)
