UkoKoshka [18]3 years ago
4 0

Answer : Capacitors

Explanation : Capacitors are normally  placed on transmission or distribution lines when to reduce inductive reactance.

This is because it enhances electromechanical and voltage stability , limit voltage dips at network nodes and reduces the power loss.

So, we can say that inductive reactance normally replace by the capacitors.

You place a +1.00 mC charged object in an electric field of 900 N/C that points due East. Determine the magnitude and direction
Kay [80]

Answer:

0.9 N, east

Explanation:

charge, q = 1 mC = 0.001 C

Electric filed, E = 900 N/C due east

Force, F = q E

F = 0.001 x 900

F = 0.9 N

The direction of force is same as the direction of electric field as the charge is positive in nature. So, the direction of force is also east.

Pilings are driven into the ground at a building site by dropping a 2250 kg object onto them. What change in gravitational poten
den301095 [7]

Answer: 324.135 kJ

Explanation:

Given

Mass of dropping is m=2250\ kg

The initial height of dropping is h_1=16\ m

The final height of dropping h_2=1.3\ m

Gravitational potential energy is the function of height i.e.

\Rightarrow \text{G.E.}=mgh

Change in Gravitational Energy is

\Rightarrow \Delta \text{G.E.}=mg(h_1-h_2)=2250\times 9.8\times (16-1.3)\\\\\Rightarrow \Delta \text{G.E.}=3,24,135\ J\approx 324.135\ kJ

If it took 125 seconds to complete 5 wave cycles, what is the period of the wave?
finlep [7]

The period of the wave is 25 s

<u>Explanation:</u>

To find the period of the wave, we have the formula

T= seconds/ no of cycle

T= 125/5

T= 25 s

The period of the wave is 25 s
