What is a 1:10 scale Batmobile?

A beaker of water rests on a scale. You slowly lower a piece of metal into the water, using a string attached to the metal, but you do not allow the metal to touch the walls or bottom of the beaker.
(a) What happens to the reading on the scale when you do this?
(b) How does the scale "know" that the metal is in the water since the metal never touches either the beaker or the scale? (It might help to draw a figure.)

John is 60 years old. He plans to retire in 2 years. He now has $400,000 in a savings account that yields 2.1% interest compounded monthly. He has calculated that his final working year's salary will be$88,000. He has been told by his financial advisor that he should have 60-70% of his final year's annual income available for use each year when he retires. Assume that John is planning on using 65% of his current salary in each of his first 5 years of retirement. What should that annual amount be?

A $100 \mathrm{~W}$ halogen incandescent lightbulb may have a resistance of about $12 \Omega$ when cold $\left(20^{\circ} \mathrm{C}\right)$. What is its resistance when "on", at $2900 \mathrm{~K}$ ? Assume an average temperature coefficient of resistivity $\alpha=0.0045\left(\mathrm{C}^{\circ}\right)^{-1}$.
