Chapter 1: Q18DQ (page 390)

A piece of iron is glued to the top of a block of wood. When the block is placed in a bucket of water with the iron on top, the block floats. The block is now turned over so that the iron is submerged beneath the wood. Does the block float or sink? Does the water level in the bucket rise, drop, or stay the same? Explain

Short Answer

Expert verified

The block will float. The level of water in the bucket will remain the same.

Step by step solution

01

Analysis of Archimedes’ principle

Archimedes' principle explains why a fluid's weight is equal to the specific force acting on it when displaced by aparticular object. It happens as a result of the buoyant force that acts on it.

02

Explanation of cause of floating

The block will still float when the iron piece is submerged. It will displace a greater volume of water than before when it sinks, and the block displaces the same amount of water as before that is equal to the block鈥檚 weight.

Thus, a floating-type object like a block displaces enough water to keep the water level constant while floating.

A car travels in the +x-direction on a straight and level road. For the first 4.00 s of its motion, the average velocity of the car is Vav-x=6.25m/s. How far does the car travel in 4.00 s?

Calculate the earth鈥檚 gravity force on a 75-kg astronaut who is repairing the Hubble Space Telescope 600 km above the earth鈥檚 surface, and then compare this value with his weight at the earth鈥檚 surface. In view of your result, explain why it is said that astronauts are weightless when they orbit the earth in a satellite such as a space shuttle. Is it because the gravitational pull of the earth is negligibly small?
