Answer:

$a=0.4\ m/s^2$

Explanation:

1. Given that,

Initial speed of a bicycle, u = 4 m/s

The final speed of a bicycle, v = 6 m/s

Time, t = 6 s

We need to find the acceleration of the bicycle. We know that, acceleration is equal to the change in speed divided by time taken. So,

$a=\dfrac{v-u}{t}\\\\a=\dfrac{6-4}{5}\\\\a=0.4\ m/s^2$

So, the acceleration of the bicycle is equal to $0.4\ m/s^2$ .

1. What happens when like charges are brought closer to each other?<br><br><br>

deff fn [24]

Like charges repel each other; unlike charges attract. Thus, two negative charges repel one another, while a positive charge attracts a negative charge. The attraction or repulsion acts along the line between the two charges. The size of the force varies inversely as the square of the distance between the two charges.
