A child playing in a swimming pool realizes that it is easy to push a small inflated ball under the surface of the water whereas a large ball requires a lot of force. The child happens to have a styrofoam ball (the shape of the ball will not distort when it is forced under the surface), which he forces under the surface of the water. If the child needs to supply 554 N to totally submerge the ball, calculate the diameter d of the ball. The density of water is p1.000 x 10¹ kg/m', the density of styrofoam is Ploum 95.0 kg/m³, and the acceleration due to gravity is g = 9.81 m/s². W

A rubber duck floats in a bathtub. Imagine moving the duck by a small amount in different directions such as up and down or side to side. Is the floating duck in stable, unstable, or neutral equilibrium?
A fish rests on the bottom of a bucket of water while the bucket is being weighed on a scale. When the fish begins to swim around, does the scale reading change? Explain your answer.
A crass host pours the remnants of several bottles of wine into a jug after a party. He then inserts a cork with a 2.00-cm diameter into the bottle, placing it in direct contact with the wine. He is amazed when he pounds the cork into place and the bottom of the jug (with a 14.0-cm diameter) breaks away. Calculate the extra force exerted against the bottom if he pounded the cork with a 120-N force.
A girl has a large, docile dog she wishes to weigh on a small bathroom scale. She reasons that she can determine her dogs weight with the following method. First she puts the dogs two front feet on the scale and records the scale reading. Then she places only the dog's two back feet on the scale and records the reading. She thinks that the sum of the readings will he the dogs weight. Is she correct? Explain your answer.
Marbles dropped into a partially filled bathtub sink to the bottom. Part of their weight is supported by buoyant force, yet the downward force on the bottom of the tub increases by exactly the weight of the marbles. Explain why.
The outward force on one end of an air tank was calculated in Example 11.2. How is this force balanced? (The tank does not accelerate, so the force must be balanced.)
Two expressions were used for the drag force experienced by a moving object in a liquid. One depended upon the speed, while the other was proportional to the square of the speed. In which types of motion would each of these expressions be more applicable than the other one?
When a glass bottle full of vinegar warms up, both the vinegar and the glass expand, but the vinegar expands significantly more with temperature than does the glass. The bottle will break if it is filled up to its very tight cap. Explain why and how a pocket of air above the vinegar prevents the bottle from breaking.
The “lead” in pencils is a graphite composition with a Young’s modulus of approximately 1.0109N/m2 . Calculate the change in length of the lead in an automatic pencil if you tap it straight into the pencil with a force of 4.0N . The lead is 0.50mm in diameter and 60mm long.
Is it easier for a large person to float in a lake than a small person? Explain.
When you push a pices of chalk across a chalkboard. It sometimes screeches because it rapidly altemates between slipping and sticking to the board. Describe this process in more detail, in particular, explaining how it is related to the face that kinetic is less than static friction. (The same slip-grap process occurs when tires screech on pavament.)
