For part of our orbit the northern half of Earth is tilted toward the Sun. This is summer in the northern hemisphere; there are longer periods of daylight, the Sun is higher in the sky, and the Sun's rays strike the surface more directly, giving us warmer temperatures
The formula for speed is distance traveled divided by time
here force between two particles is given by Coulomb's law where two particles will either repel or attract each other
this force of attraction or repulsion is given by the equation

here we know that
= two point charges
r = distance between two charges
so now we will substitute all values in it

so above is the force between two point charges
Answer:
Slow
Explanation:
As we know that the time period of simple pendulum is given by

Where, l be the effective length of the pendulum and g be the acceleration due to gravity
As the length of the pendulum increase, then the tie period of the pendulum will also increase.
It means the clock run slow.
Answer:
0.25 m/s
Explanation:
Average velocity = change in displacement / change in time
v = (1.5 m − 2.5 m) / (6 s − 2 s)
v = -0.25 m/s
The average speed is 0.25 m/s.
