Answer:
a
The total distance is 
b
The displacement is

Explanation:
From the question we are told that
Distance traveled by the ball for first player
to the right
Distance traveled by the ball for second player
to the left
The total distance traveled by the ball is mathematically represented as

Substituting values


The displacement is mathematically represented as
This is because displacement deal with direction and from the question we are told that right is positive and left is negative
Substituting values


A
It loses motion through the forms of heat, light, sound and electricity charge
Answer:
The correct option is;
c. Temperature and color
Explanation:
Based on Wien's Law which can be presented mathematically as follows;

The wavelength of the peak of the blackbody curve tells the temperature and color.
An example is the Sun that has a temperature of 5800 K, hence the peak wavelength is given by
= 500 nano-meter from which the color can be deduced as 500 nano-meter is the wavelength of yellow light.
