Knowing that the density of cow's milk must be between these two values: 1,023 g / mL and 1,034 g / mL, so that if the milk is watered down, its density is less than 1,023 g / mL,
describe how you would investigate whether or not a milk is watery

A6,600 kg train car moving at +2.0 m/s bumps into and locks together with one of mass 5,400kg moving at -3.0m/s. what is their final velocity? +0.50 m/s -1.0 m/s +2.5 m/s -0.25 m/s

Agroup of students were investigating the force of gravity. they began by dropping a foam ball from a height of 3 meters into a bucket of sand. the ball hit the sand in 0.306 seconds. they dropped additional balls of approximately the same diameter, but of different masses. here is the data they collected. based on this experiment and the collected data, what would their conclusion be?

Ais a machine that makes work easier when a single force is applied. a simple machine b compound machine c endangered machine d complex machine
