1) When you apply a constant force to an object does the object move at a constant velocity or does its velocity increase? Explain why this occurs using your understanding of acceleration/force (gravity).

Agirl throws a ball. if the ball's acceleration is 12 m/sec/sec and its mass is 0.5 kg, how much force did the girl apply to the ball?

Which of the following statements are evidence that gases do not always behave ideally? check all that apply.? a. co2 gas becomes dry ice (solid co2) at 1 atm and –78.5 °c. b. when two gases are mixed, they follow dalton\'s law of partial pressures. c. at 4 k and 1 atm, helium is a liquid. d. it is impossible to compress a gas enough so that it takes up no volume.

You have 80 g of 60oc water and 80 g or 10oc water. what is the final temperature when the two are mixed? explain.
