On paper, make a careful scale drawing of the two rhenium nuclei just after fission, and label the drawing with the distances that you just calculated. if the two rhenium nuclei are nearly touching, this would be consistent with our model of fission, in which the th-230 nucleus fissions into two pieces that are initially nearly at rest. how big is the gap between the surfaces of the two nuclei? (if you have done the calculations correctly, you will indeed find that the gap is a rather small fraction of the center-to-center distance, which means that our simple model for the fission process is a pretty good model.)

Aball tossed vertically upward from the ground next to a building passes the bottom of a window 1.8 s after being tossed and passes the top of the window 0.20 s later. the window is 2.0 m high from top to bottom. what was the ball's initial velocity? the unit vector j^ is directed upward. how far is the bottom of the window from the launch position? how high does the ball rise above the launch position?

The intensity of a polarized electromagnetic wave is 12 w/m^2. part a) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=0∘ with the plane of polarization? part b) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=30∘ with the plane of polarization? part c) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=45∘ with the plane of polarization? part d) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=60∘ with the plane of polarization? part e) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=90∘ with the plane of polarization?
