Answer:
Approximately (assuming that the car is moving on level ground, and that there is no friction to hinder the motion of the car.)
Explanation:
Formula for the kinetic energy, , of an object of travelling at velocity :
.
Let and denote the velocity of this car before and after the acceleration.
Kinetic energy of this car before the acceleration:
.
Kinetic energy of this car after the acceleration:
.
Assume that this car was travelling on level ground. Also assume that there is no friction to hinder the motion of this car. The work of the engine of this car would be equal to the amount of that the car has gained:
.
No, water is the thing that gets pollutant, then again due to all the pollution in water it can cause to hurt others with the pollution
Answer:
7.401 * 10^(-15) N
Explanation:
30 electrons will have a charge:
30 * -1.6022 * 10^(-19) C
= - 4.806 * 10^(-18) C
The relationship between electric field and electric force is:
E = F/q
This means that force, F, is
|F| = |E|*|q|
|F| = |1540| * |-4.806 * 10^(-18)|
|F| = |-7401.24 * 10^(-18)|
|F| = 7.401 * 10^(-15) N
