A balloon filled with helium has a small hole on the right side of the balloon. How would Pascal explain why the entire balloon shrinks in volume rather than only the right side, near the hole, shrinking in volume?

The roller coaster from problem #1 then tops a second hill at 15.0 m/s, how high is the second hill? 91.5 m 79.2 m 80.0 m 68.5 m

Avalue that describes how heavy an object is and is related to the force of gravity is

In all trials, the magnitude of the final velocity for g1 + g2 was less than the magnitude of any initial velocity. as mass increased, what happened to the velocity? the velocity decreased. the velocity increased. the velocity of g1 + g2 could not be measured. the velocity was not affected by the mass increase.
