Explain why a balloon expands when taken to a higher elevation if the temperature remains constant?

Starting with an initial speed of 6.63 m/s at a height of 0.473 m, a 1.67-kg ball swings downward and strikes a 5.91-kg ball that is at rest, as the drawing shows. (a) Using the principle of conservation of mechanical energy, find the speed of the 1.

If an element has the atomic mass (a) of 80 and its atomic number (z) is 35, how many neutrons does it have?

A ball is thrown up into the air with an initial velocity of 64 ft/sec. The ball is 4 ft above the ground when it is released. Its height, in feet, at time t seconds is given by: h (t) = - 16t^2 + 64t + 4.
