Name two objects that have a low density.

It takes about four minutes to bake a potato in a 1000 W microwave oven. How much energy is used? Answer:.07kWh

Estimate and determine the order of magnitude of the circumference of the Earth in miles and the speed of a sailboat in miles per hour. The Earth's circumference is 10^4 mile and the the speed of a sailboat is 10^1 mile/hour.

The intensity of sunlight hitting the surface of the earth on a cloudy day is about 0.50 kw/m2 assuming your pupil can close down to a diameter of 2.

A toy car goes over a small ramp at a horizontal velocity of 1.21 m/s and decelerates at 0.131 m/s2 while in the air. The total time elapsed was 0.342 seconds. What was the horizontal distance traveled?

8. Why are objects that fall near Earth's surface rarely in free fall? Gravity does not act on objects near Earth's surface. Air exerts forces on falling objects near Earth's surface. The objects do not reach terminal velocity.
