Q1. A small statue in the shape of a falcon is painted black and has a weight of 24.1 N. The owner of the statue claims it is made of solid gold. What time the statue is completely submerged in a container brimful of water, the weight of the water that spills over the top and into a bucket is 1.25 N. Find the density of metal. Is the density consistent with the claim that the falcon is solid gold?
Q2. A 55.0 kg girl weighs herself by standing on a scale in an elevator.
a)What is the force exerted by the scale when the elevator is descending at the constant speed of 10 m/s?
b)What is the force exerted by the scale if an elevator is accelerating downward with an acceleration of 2.7 m/s2
c)If the elevator's descending speed is measured at 10 m/s at a given point, but its speed is decreasing by 2.7 m/s2, what is a force exerted by the scale?
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..
