Physics
A ball with mass m = 0.210 kg and kinetic energy K1 = 2.97 J collides elastically with a second ball of the same mass that is initially at rest. After the collision, the first ball moves away at an angle of = 30.6° with respect to the hori- zontal, as shown in the figure. ...

chemistry
Consider the following reaction: 2H2S (g) + 3O2 (g) --> 2SO2 (g) + 2H2O (g) If O2 was the excess reagent, 1.3 moles of H2S were consumed, and 18.7 g of wat were collected after the reaction has gone to completion, what is the percent yield of the equation?

A 570.0 g ball moves in a vertical circle on a 103.0 cm-long string. If the speed at the top is 4.30 m/s, then the speed at the bottom will be 10.65 m/s. (you'll learn how to show this Chapter 10.) What is the gravitational force (in N) acting on the ball? What is the ...
