Answer:
Power= 6.84×10⁸ W
Explanation:
Given Data
Niagara falls at rate of=1.4×10⁶ kg/s
falls=49.8 m
To find
Power Generated
Solution
Regarding this problem
GPE (gravitational potential energy) declines each second is given from that you will find much the kinetic energy of the falling water is increasing each second.
So power can be found by follow
Power= dE/dt = d/dt (mgh)
Power= gh dm/dt
Power= 1.4×10⁶ kg/s × 9.81 m/s² × 49.8 m
Power= 6.84×10⁸ W
Answer:
No force is generated
Explanation:
Solution:-
- The reason that current carrying parallel wires exert forces between them is that the magnetic field of the one is perpendicular to the velocity of the electrons in the other one (current = moving electrons).
- The magnetic force Fm is given by the cross product of velocity vector (v) and strength of magnetic field (B):
Fm = q* ( v x B ).
- In perpendicular (current carrying) wires, the magnetic field of one wire is in parallel with the velocity of the electrons in the other one, and, thus, no force is generated.
Fm = q * // ( v x B )
= q * ( 0 ) = 0
- The cross product of parallel vectors is zero.
