- The capacitor

The parallel square plates of a 4.5µF Teflon capacitor are 3.2 mm apart. What is the area of the plate? - The intensity

The light intensity on a screen is inversely proportional to the square of the distance between the screen and the light source. If a screen is illuminated by a light source 20 m away, the intensity is one-fifth of what is required. Where should the light - Tom can

Tom can run 3/4 of a mile in 1/8 of an hour. What is the unit rate in miles per hour? - Noel drives

Noel drives at an average speed of 52 miles per hour (mi/h) for 3 1/4 hours. How far has he traveled for 3 1/4 hours? - An airplane 3

An airplane descends at a rate of 2,700 feet per minute. Once the airplane starts its descent, what will be its elevation, in feet, after 3 1/5 minutes? - Feed rate

The feed rate of a drill is the distance it advances with each revolution. If a drill makes 320 rpm and drills a hole 2.625 inches deep in 1.8 minutes, what is the feed rate? - The temperature 47

The temperature in a garden at midnight was −3 degrees Celsius. By 6 AM, the temperature was −8 degrees Celsius. What is the difference in the temperature? - Water 71

Water was heated to 80°c then allowed to cool at a rate of 6°c per minute. After how long was the temperature 8°C? - Lightning strike

In a thunderstorm, the formula M=t/5.3 gives the approximate distance, M, in miles, from a lightning strike if it takes t second to hear the thunder after seeing the lightning. If you are 5.4 miles away from the lightning flash, how long will it take the - Balloon

If a ceiling balloon rises at 120 m (about 400 ft) each minute, what is the ceiling of an overcast deck of stratus clouds 1500 m (about 5000 ft) thick if the balloon disappears into the clouds in 5 minutes? Show your solution. - Konrad

Konrad coaches football. He cycles 3 km to the stadium at an average 12 km/h speed. How long does Konrad take to cycle to the stadium? - The temperature 45

The temperature in a field is 68°F at 4 PM. The temperature decreases by 4°F per hour. When will the temperature be 60°F? - One evening 2

One evening, the temperature in Miami was 28°C. During that same evening in Anchorage, it was 32°C cooler than it was in Miami. What was the temperature in Anchorage? - Heat energy

Energy is measured using the unit Joule (J). Temperature is measured using the unit degree Celsius °C). To increase the temperature of 1 liter of water by 1°C, 4200 J of heat energy is required. (a) Kelly wants to increase the temperature of 2 liters of w - Water level

Between 9 PM and 6:36 AM, the water level in a swimming pool decreased by 6/35. Assuming that the water level decreased at a constant rate, how much did the water level drop each hour? - The temperature 39

The temperature outside is currently 10 degrees, dropping at an average rate of 2 degrees per hour. If the temperature continues to drop at this rate, what will the temperature be in 7 hours? - Zendaya

Zendaya walked 6 miles in 5 hours. What was her walking rate in hours per mile? - A piece 8

A piece of metal has a mass of 2210 g. The volume of the metal is 260 cm³. What is the density? - This morning 2

This morning the temperature outside was -4 degrees. This afternoon the temperature was 21 degrees warmer. What was the temperature this afternoon? - The temperature 38

The temperature has been dropping 2 degrees every hour, and the temperature at 10:00 AM was -15 degrees Fahrenheit. At what time was the temperature 0 degrees Fahrenheit?
