Suppose now you set up the experiment so that the plate is NOT ejecting electrons. Predict which of the following changes to the experiment could make the plate start ejecting electrons. (Select all that apply-Options are the same as in the previous problem) Then test your prediction. 10.(1 Point) What causes the electrons to be ejected from the left plate in this simulation? A. The force exerted on the electrons by the battery B. The beam of light shining on the plate C. Both A and B D. Neither A nor B.

Apossible explanation for a set of facts that can be tested by further investigation is called

During spring semester at mit, residents of the parallel buildings of the east campus dorms battle one another with large catapults that are made with surgical hose mounted on a window frame. a balloon filled with dyed water is placed in a pouch attached to the hose, which is then stretched through the width of the room. assume that the stretching of the hose obeys hooke's law with a spring constant of 89.0 n/m. if the hose is stretched by 5.80 m and then released, how much work does the force from the hose do on the balloon in the pouch by the time the hose reaches its relaxed length? unitst 3 number-1497 the tolerance is +/-5% open show work click if you would like to show work for this question:
