Mechanical and Chemical. (Weathering and erosion)
It means that if the mass of a mass is increased by some factor, and nothing else changes, then the weight of that mass increases by exactly the same factor.
Answer:
All of teh above except A
Explanation:
Geothermal energy.
Electromagnetic energy originates at the sun (think UV rays; they are part of the electromagnetic spectrum). Electrical energy technically can be anywhere, as long as there are positive and negative charges. Mechanical energy is like a generator or an engine; there is always something working to get things done/made.
I hope this answer and these explanations helped!
You probably do this as a DC circuit which is not quite correct, but it will get you an answer. The study is a great deal more complicated.
Problem One: Secondary Power.
W = E * I
E = 10 A
I = 24V
W = 24 * 10
W = 240 Watts.
Here's the thing you have to know. These transformers are 100% efficient (or are assumed so). So whatever wattage is in the secondary, it is the same as that in the primary.
Primary Power = Secondary Power
Secondary Power = 240 Watts
Primary Power = 240 Watts
W = E * I
E = 240 volts
W = 240 watts
I = W/E = 240 / 240
I = 1 Amp. Answer Part One
Part Two
Answered above. 240 watts.
Part Three
Answered above. 240 watts.
