If one of the two electrons of a H2 molecule is removed, we get a hydrogen molecular ion. In the ground state of an, the two protons are separated by roughly 1.5 Å, and the electron is roughly 1 Å from each proton. Determine the potential energy of the system. Specify your choice of the zero of potential energy.
A circular metal loop whose radius is 6:0 cm carries a current of 5:0 A. It is horizontal, while the earth's field points North and 60? below the horizontal. (The earth's field has a magnitude of about 0:50 Gauss, which is 0:5 10?4 T.
A bale of hay sits on the bed of a trailer. The trailer is starting to accelerate forward, and the bale is slipping toward the back of trailer. What would a force diagram and a free-body diagram look like for the above situation.
Suppose the force acting on a tennis ball (mass 0.040 kg) points in the +x direction and is given by the graph of Fig. 7-30 as a function of time. a) Use a graphical method to estimate the total impulse given the ball.
