Answer: a) 18670 W b) 25 hp

Explanation:

a)

Average power,

P = W/t

W= 0.5 MVf^2 - 0.5 MVo^2

Therefore P =( (0.5 x 112 x 34.5^2 ) - (0.5 x 112 x 0 ) ) / 3.57

P = 1.87 x 10^4 W

b)

Power in units of horsepower is

P = 1.87 x 10^4 / 745.7 = 25hp

Nataliya [291]

If the point charge is placed at point E_W is equal to E_X.

<h3>Electric field inside a conducting cubic shell</h3>

The electric field inside a conducting cubic shell is zero. When a point charge is placed outside the shell, the electric field outside the shell is greater than the electric field inside the shell which is zero.

We can deduce the following;

  • Electric field inside the shell is zero, thus E_W = E_X =0
  • Electric field outside the shell is greater than electric field inside the shell

Thus, the only correct statement is, If the point charge is placed at point E_W is equal to E_X.

What factors determine the magnitude of the electric force between two particles ?
svp [43]
The electric force between the two particles are calculated through the equation,
 
                          F = kQ₁Q₂ / d²

where F is the force, k is a constant called Coulomb's law constant, Q₁ and Q₂ are the charges, and d is the distance. This equation is called the Coulomb's law. 

It can be seen from the equation above that the electric forces between the objects are majorly affected by the substance's charges and distance. 

The answer to this item is therefore letter A.
