Answer:9.34 A/s
Explanation:
Given
radius of solenoid 
Emf induced 
no of turns per meter n=450
we know Induced EMF is given by
Magnetic Field is given by
thus 
Area of cross-section
where
solving integration we get
where r=distance from axis
R=radius of Solenoid
Answer:
70713
Explanation:
Because you need to multiply the amount of water lost (2430) by the time (29.1) which will equal 70713J/g needed to counter the loss.
Hope this helps:)
Answer:
No getting rid of fossil fuel is not at all possible.
Explanation:
Dream of 100% renewable energy is possible through electrification and use of energy from sun, water and wind. Since, the high production cost of power plant for extracting energy from these sources in itself is a big challenge and hence decarbonized energy in current scenario is not realistic.
the position that has least kinetic energy is option D
