Answer:

lightning

Explanation:

correct answer is Lightning because it is the naturally occurring electrostatic discharge, during 2 electrically charge field in atmosphere and on the ground temporarily equalize themselves and they instantly release energy.
As it is released cloud so we called it lightning but a spark is generated when the electric field strength is sufficient to ionize the molecules of air, creating a small conduction path through the air.
This is usually a cascade process, because free electrons accelerate in the electric field and ionize more molecules by colliding.

3. Suppose that you have an electrically charged stick. If you divide the stick in half, each half will have half the original c

FrozenT [24]

Answer:

No, you can't keep on dividing the charge forever.

Explanation:

No, you can't keep on dividing the charge in that manner forever because the total charge of the stick is an integer multiples of individual units known as an elementary charge, which is the electron (e) charge (e = 1.602x10⁻¹⁹C).

Therefore the limit of the division of the original charge will be the electron charge since it is the smallest charge that can exist freely.

Two long, parallel wires are separated by a distance of 3.20 cm. The force per unit length that each wire exerts on the other is

AURORKA [14]

Answer:

(a)The current in the second wire = 9.43 A

(b) The two current are in the opposite direction.

Explanation:

The force per unit length (F/l) on a current carrying conductor = μ₀I₁I₂/2πr

Making I₂ The subject of the equation,

I₂ = [2πr(F/l)]/μ₀I₁.................... Equation 1

Where I₁ = Current in the first wire, I₂ = current in the second wire, μ₀ = permeability of vacuum, r = distance of separation between the two wires.

Given: F/l = 3.30 × 10⁻⁵ N/m, I₁ = 0.56 A, r = 3.20 cm = 0.032 m.

Constant: μ₀= 4π × 10⁻⁷ Am⁻¹.

Substituting these values into equation 1

I₂ = (2π × 0.032 × 3.30 × 10⁻⁵ )/(4π × 10⁻⁷×0.56)

I₂ = (0.032 × 3.3 × 100)/1.12

I₂ = 10.56/1.12

I₂ = 9.43 A

Therefore the current in the second wire = 9.43 A

(b) The two current are in the opposite direction, because the force on each wire repel each other.

A professional quarterback throws a 0.40 kg football. what is the force of weight?

Katyanochek1 [597]

Answer:

3.92N

Explanation:

Force= mass×accelerarion due gravity

But mass= 0.40kg

acceleration due to gravity = 9.8 m/s^2

Force = 0.40×9.8

Force=3.92N

A car travels at an average speed of 60 km / h for 15 minutes. How far does the car travel in 15 minutes?

salantis [7]

Answer:

15km

Explanation:

Given parameters:

Average speed = 60km/hr

Time taken = 15min

Unknown:

Distance = ?

Solution:

The distance traveled can de derived using the expression below;

Distance = Average speed x time taken

Now let us convert the time to hr;

60min = 1hr

15min = $\frac{15}{60}$ = 0.25hr

Distance = 60km/hr x 0.25hr = 15km
