Yes, yea, yep, you don't make much sense.
Kinetic Energy = (1/2) mv^2.
m = 57.7 g = 57.7/1000 = 0.00577 kg.
v = 325 m/s.
E = 0.5 * 0.00577 * 325^ 2. Use your calculator.
E = 304.728125 J.
That's the kinetic energy.
Answer:
here
Explanation:
Copper is commonly used as an effective conductor in household appliances and in electrical equipment in general. Because of its low cost, most wires are copper-plated. You will often find electromagnet cores normally wrapped with copper wire
Answer:
D. 130 J
Explanation:
The coefficient of performance for a machine that is being used to cool, is given by:
Here is the heat removed from the cold reservoir, W is the work required, that is, the energy required to remove the heat from the interior of the house, is the cold temperature and is the hot temperature. Recall use absolutes temperatures(). Replacing and solving for W:
Answer:
-The battery-the power source
-Closed conducting loop
Explanation:
-To produce an electric current, the following requirements must be met:
-A battery-This is the energy source than will do work on the charge thus moving from a low energy location to high energy location.
-Closed Conducting Loop-The loop is usually made of copper wires due to their high electric conductivity.
