The older students should be able to complete the puzzle in a shorter amount of time than the younger students
The answer is D) second/meter
Explain why the output voltage from a transformer<span> is </span>zero if<span> a </span>direct current<span> flow through the </span>primary coil<span>. Only an alternating </span>current<span> induces the </span>voltage<span> in the</span>transformer<span>. ... Alternating </span>current<span> is used because </span>transformers<span> can increase or decrease </span>voltage<span>.</span>
Answer:
The potential energy can be given as
E = mgh. m is mass, g = acceleration due to gravity = 9.8m/s, h is the heigh, given as 100.0m
E = m x 9.8 x 100 = (980m)J
E = (980m)/10^9GJ = (0.000000980m)GJ to 3 significant figures
Explanation:
Hydroelectric dams exploit storage of gravitational potential energy. A mass, m, raised a height, h against gravity, g = 9.8 m/s², is given a potential energy E = mgh. The result will be in Joules if the input is expressed in meters, kilograms, and seconds (MKS, or SI units).
