Comparing the clouds of earth and venus, we find that: a. venus has much more carbon dioxide, so dry ice clouds dominate. b. like ours, they rotate around venus slower than venus rotates on its axis. c. both are made chiefly of water vapor. d. venus is too hot for clouds to form, so we see only a barren world telescopically. e. ours lie in the troposphere, within 10 kilometer of our surface, but venus has a higher troposphere, with its clouds about 40 kilometers high.

What is the speed of an object at a given moment?

16. a brave but inadequate rugby player is being pushed backward by an opposing player who is exerting a force of 800 n on him. the mass of the losing player plus equipment is 90.0 kg, and he is accelerating at 1.20m/s2 size 12{1 "." "20"" m/s" rsup { size 8{2} } } {} backward. (a) what is the force of friction between the losing player’s feet and the grass? (b) what force does the winning player exert on the ground to move forward if his mass plus equipment is 110 kg? (c) draw a sketch of the situation showing the system of interest used to solve each part. for this situation, draw a free-body diagram and write the net force equation.
