Answer:
lift per meter of span = 702 N/m
Explanation:
See attached pictures.
The input force will be less than the output force
Resistors 'C' and 'D' are in series. There's only one possible route for current to flow through them.
Every electron that flows through one of them has to flow through the other one.
The current (amount of charge per second) must be the same in 'C' and 'D', no matter how many ohms of resistance either one may have. <em>(answer-choice B)</em>
The type of ions that electrons collide with to cause resistance in a circuit is B. Metallic
Answer:
5.3 cm
Explanation:
Let the charges on the spheres be q and Q.
r = 9.20 cm
F = k Q q / (9.20)^2 ..... (1)
Let the new distance be r' and force F'
F' = 3 F
F' = k Q q / r'^2
3 F = k Q q / r'^2 ...... (2)
Divide equation (1) by (2)
F / 3 F = r'^2 / 84.64
1 / 3 = r'^2 / 84.64
r' = 5.3 cm
