cm left of the converging lens
(b) Where will the image be if the diverging lens is 34 cm from the converging lens?
cm right of the diverging lens
If it takes 3 golf balls to equal the mass of one tennis ball, what weight of tennis balls do you require equalling the number of golf balls in one kilogram of golf balls.
An alpha particle (m = 6.7 ´ 10-27 kg, q = +3.2 ´ 10-19 C) has a speed of 20 km/s at point A and moves to point B where it momentarily stops. Only electric forces act on the particle throughout this motion. Find out an electric potential difference V..
