Hot water, as in very hot water, goes to steam with an enormous change in volume and pressure. This is capable of driving turbine blades, which in turn rotate enormous copper (eg) wired coils in enormous magnetic fields. This in turn produces electricity via electromagnetic induction and Fleming's right hand (I think it is) DYNAMO rule. That goes down miles and mile of v heavy conducting wire/cable as electricity.
Yes. Momentum is a vector, so several non-zero momenta can add up to zero. Consider for a simple example a mass of 10kg moving to the right at 5m/s, and another mass of 10kg moving to the left at 5m/s. These momenta each have a magnitude equal to 50 kg m/s but have opposite sign and so the total system's momentum is zero.
Answer:
19500kg
Explanation:
If you divide 195000N by 10
Answer:
1.974 g
Explanation:
Electrochemical equivalent of copper, z = 0.000329 g/C
I = 10 A
t = 10 minutes = 10 x 60 = 600 seconds
By the use of Farady's law of electrolysis
m = z I t
m = 0.000329 x 10 x 600
m = 1.974 g
