The contribution to the nature of light-
Thomas Young - wave nature of light (double-slit experiment)
Max Planck - E = hv
Albert Einstein - a quantum theory of light
Thomas Young proposed the most important double-slit experiment which shows that light acts like a wave and shows the pattern of interferences.
Max Planck proposed that light is proportional to frequency. He gave the equation, E = hv, where E is the energy of light, h is Planck's constant, and v is the frequency.
Albert Einstein proposed the quantum theory of light. He determined that light exists in discrete quanta of energy called photons.

Explanation:
First, we will calculate fuel consumption is as follows.

= 4526 g/s
Now, we will calculate the power as follows.
Power = Fuel consumption rate × -enthalpy of combustion
= 
=
kW
Thus, we can conclude that maximum power (in units of kilowatts) that can be produced by this spacecraft is
kW.
