1. If the radius of a star increases by a factor of 7 the surface area of the star increases how many times?
2. If the radius of a solid object increases 5 times, the volume of the object will increase how many times?
3. A battery has an internal voltage (EMF) of 12 and an internal resistance of 5 ohms. If the terminal voltage of the battery is 9.5 volts, calculate the current through the battery (in milliamps).
4. If 1.2 amp flows through a 40 ohm resistor, the voltage across the resistor is:
5. A battery has a terminal voltage of 8 volts when a current of 500 milliamps flows through it. The internal resistance of the battery is 5 ohms. Calculate E, the internal voltage (EMF), of the battery.
6. Calculate the voltage (in volts) of a solar cell that generates a current of 69 milliamps and has a resistance of 6 ohms.
7. A pendulum has a length of 1.6 meter and a mass of 200 grams. Calculate the period (in seconds) of the pendulum.
8. A battery is labeled with a voltage of 9 volts. When the battery is connected to a resistor, the current is 1.2 amp and a digital voltmeter placed across the battery measures 7.8 volts. What is the internal resistance of the battery?
9. If the temperature of an object is multiplied by 6 , the amount of power radiated is multiplied by what number?

Determine approximate number of radioactive counts
: The detector has a surface area of 0.012m^2. An average human has a surface are of approximately 3.3m^2. Use these facts to determine the approximate number of radioactive counts an average human will recieve in a day.

Create an isometric drawing from scratch
: You must also submit a detailed written report of how the drawing was created. This will account for 20% of the grade. Dimensions will be 20% and the drawing itself will account for 60% of the grade for the final project.
