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?
