Answer:
Option C
Explanation:
The graph shows endothermic reaction because the reactants are lower in energy and the products are higher is energy. Endothermic reactions absorb energy having products with higher energy.
Johannes Kepler contributed to the study of planets : He provided mathematical support for the heliocentric model.
<h3>What is Kepler's first law of planetary motion?</h3>
Kepler's first law of planetary motion states that the planets revolve around the Sun in orbits elliptical in shape with the Sun at its one of the focus.
As the planets rotate around the Sun, the relative distance between the Sun and planets increases and decreases.
The heliocentric model in which the Earth and planets revolve around the Sun at the center of the universe. Johannes gave the mathematical calculations of this model.
Thus, last option is correct.

Acceleration a = 3 ms²
time t = 4 s ,
initial velocity vi = 0 ( not given )
Distance = s= ?
distance =s= by using equation = s= vit + 1/2 at²
= 0*4 + 1/2 * 3*(4²)
= 24m.
It's simple. You just need to apply formular onto problem.
