The second ball traveled a greater distance when compared to the first ball because the second ball spent more time in motion.
The given parameters;
- time of fall of the first ball, t = 1 s
- time of fall of the second ball, t = 3 s
The distance traveled by each ball is calculated using the second equation of motion as shown below.
The distance traveled by the first ball is calculated as follows;
The distance traveled by the second ball is calculated as follows;
Thus, the second ball traveled a greater distance because it spent more time in motion.

Explanation:
Generally the force of attraction between this two irons is mathematically represented as
Here k is known as the proportionality constant with value
substituting -2 for i.e the charge on oxygen , +1 for i.e the charge on Lithium and for r
So
Generally the force of repulsion will be the magnitude but different direction to the force o attraction
So Force of repulsionn is
Answer:
Rate of change of area will be
Explanation:
We have given rate of change of radius
Radius of the circular plate r = 52 cm
Area is given by
So
Puting the value of r and
So rate of change of area will be
