Question 3 (1 point) Two objects have equal negative charge and repel each other with a force Fwhen separated by a distance x. Suppose the object on the left gets 4x its original charge, the charge on the right is left alone, and the distance is between them is changed to The force between the two objects is now ---Use Columb's Law F=Kq1*92/r2 ​

Distinguish between linear momentum and angular momentum

(8%) problem 12. a bowling ball of mass mb 3 kg 's rolled down the lane with a velocity ofy-2/ m s lt strikes a single remaining pin mp 0.93 kg head on. after the collision the bowling ball has a velocity (in the same direction) of v2 1.1 m/s. = ▲ 33% part (a) write an expression for the velocity of pin in the horizontal direction after the impact, im ,, 33% part (b) what is the pins speed in ms? 33% part (c) assuming the coefficient of friction s μ,-0.1. how far in meters could the pin slide before stopping if it doesn't topple?
