Answer:

The answer is Negative charges repel other negative charges and attract positive charges.

Explanation:

Taking into account the law of charges, which expresses that charges of the same sign tend to repel, while charges of different signs attract; that is to say that the electrostatic force between charges of the same sign is repulsive, while said force on charges of different signs is of attraction. Therefore, it is understood that negative charges repel other negative charges and attract positive charges.

A car is moving in the positive direction along a straight highway and accelerates at a constant rate while going from point A t

rusak2 [61]

Answer:

The time where the avergae speed equals the instaneous speed is T/2

Explanation:

The velocity of the car is:

v(t) = v0 + at

Where v0 is the initial speed and a is the constant acceleration.

Let's find the average speed. This is given integrating the velocity from 0 to T and dividing by T:

$v_{ave} = \frac{1}{T}\int\limits^T_0 {v(t)} \, dt$

v_ave = v0+a(T/2)

We can esaily note that when t=T/2

v(T/2)=v_ave

Now we want to know where the car should be, the osition of the car is:

$x(t) = x_A + v_0 t + \frac{1}{2}at^2$

Where x_A is the position of point A. Therefore, the car will be at:

x(T/2) = x_A + v_0 (T/2) + (1/8)aT^2
