1. Two identical clocks are synchronized. One is then put in orbitdirected eastward around the Earth while the other remains on theEarth. Which clock runs slower? When the moving clock returns tothe Earth, are the two still synchronized?

2. Photons of light have zero mass. How is it possible that they have momentum?

3. If you hold water in a paper cup over a flame, you can bring thewater to a boil without burning the cup. How is this possible?

4. give an examle where no heat is transferred to or form asystem but the temperature of the systyem change.

why is it worng to think of heat as a form of stored energy.
