Answer:
It's true
Explanation:
I took the quiz a few days ago and got it right!
Hope this helps:)
Answer:
Explanation:
efficiency = (energy output / energy input)
energy input = ivt where i is current = 6 A, v is volts = 140 and t time = 11 seconds
energy input = 6 × 140 × 11 = 9240 J
energy output = 0.64 × 9240 = 5913.6 J
510 pound-force = 2268.593 N
at height h, potential energy = mgh = 5913.6 J
2268.593 × h = 5913.6
h = 5913.6 / ( 2268.593) = 2.61 m
The impact behavior of plastic materials is strongly dependent upon the temperature. At high temperatures, materials are more ductile and have high impact toughness. At low temperatures, some plastics that would be ductile at room temperature become brittle.
The answer to your question should be 630, if you have a roof the size of 40 feet, by 35 feet.
If the roof is 40 inches, by 35 inches, you would have collected 4.36 inches of rain.
Explanation: To calculate this you are going to do this:
Length of the roof ______ feet * width of roof _______ feet * .6 gallons per square feet *.75 * ________ however many inches of rain
* means multiply
Answer:
Gravitational force (pulled downward by the Earth)
Normal force (pushed upward by the ground)
Applied force (pushed by the person)
Friction force (pulled opposite the direction of motion by the roughness of the ground)
