A charge of 5.4 C experiences a force of 25.0 in an electric field. What is the strength of electric field at that point ? If th
Airida [17]

The strength of the electric field at that point and the force would this charge experiences at that point will be 4.587 N/C and  12.38 N.

<h3></h3><h3>What is the electric field strength?</h3>

The electric field strength is defined as the ratio of electric force to charge.

Given data;

q₁ = 5.4 C

F₁ is the electric force in case1

E is the electric field =?

F₂ is the electric force in case 2

q₂ is the charge 2

The strength of the electric field at that point is;

F₁=Eq₁

E₁=F/q₁

E₁=25.0 N / 5.4 C

E₁=4.587 N/C

The force would this charge experience at that point when the charge is 2.7 C;

F₂=Eq₂

F₂=4.587 N/C × 2.7 C

F₂ = 12.38 N

Hence the strength of the electric field at that point and the force would this charge experiences at that point will be 4.587 N/C and  12.38 N.

You've probably seen how the surface of a tire can partially melt and leave a mark on the road when a car's brakes are applied r
yan [13]

Answer:

tire marks are due to the increase in thermal energy

Explanation:

When a tire is spinning at a given speed when the brakes are applied hard, the friction between the tire's particulate and the ground surface is high enough that some tire particles are transferred to the ground.

This is reflected in the heat transfer from the tire to the ground.

Consequently, tire marks are due to the increase in thermal energy and the change in the friction force of the tire.

How fast would a(n) 75 kg man need to run in order to have the same kinetic energy as an 8.0 g bullet fired at 390 m/s
nata0808 [166]

Answer:

Explanation:

½(75)v² = ½(0.008)390²

        v² = (0.008)390²/75

        v² = 16.224

         v = 4.027...

         v = 4.0 m/s

An echo repeats two syllables.If the velocity of sound is 330 m/s , then the distance of the reflecting surface is-
Andreas93 [3]
<span>Well, the main point you should remember is that we only can hear  20hz that leads to T=0.05sec which means that the distance leads us to velocity x time.
When calculating, you get 330 * 0.05=16.5 .
The number which you got from the previous step has to me multiplied 4 times (4 minutes) and you will get the answer you need - </span><span>a) 66.0 m.
Do hope it will help you! Regards!</span>
