Abowling ball weighing 71.2 n is attached to the ceiling by a 3.60 m rope. the ball is pulled to one side and released; it then swings back and forth like a pendulum. as the rope swings through its lowest point, the speed of the bowling ball is measured at 3.90 m/s.

a. at that instant, find the magnitude of the acceleration of the bowling ball.
b. at that instant, find the direction of the acceleration of the bowling ball.
upward/downward/in the direction of motion
c. at that instant, find the tension in the rope.

Abeam of electrons with of wavelength of 7.5 x 10-6 m is incident on a pair of narrow rectangular slits separated by 0.75 mm. the resulting interference pattern is projected onto a screen 10.0 m from the slits. what is the separation of the interference maxima in the resulting interference pattern?

The two required components for a generator are

Click the game tab at the bottom of the simulation and select level 1. (there is no seesaw balance for this part of the activity.) balance the first equation, and click check to see if you got it right. if you can’t balance it in the first try, you can try again. work through the five equations for level 1. click continue to go on to level 2, and later level 3. each level is more difficult than the one before. keep trying until all the equations are balanced. in one or two sentences, describe how you did in the balancing game. in a few more sentences, explain one strategy you learned for balancing more complex equations.
