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.

Hope this helps.
Explanation:
The problem is in balancing the reaction equation;
Li + AlCl₃ → LiCl + Al
In balancing chemical equations, we must keep the law of conservation of matter in mind.
The law shows that the number of atoms on both sides of the reaction must be the same.
To balance the given equation, we set up simple, solvable algebraic mathematical expressions:
aLi + bAlCl₃ → cLiCl + dAl
Coefficients a, b,c and d
Conserving:
Li: a = c
Al: b = d
Cl: 3b = c
let b = 1;
d = 1
c = 3
a = 3
3Li + AlCl₃ → 3LiCl + Al

Answer:
Acceleration, rate at which velocity changes with time, in terms of both speed and direction. A point or an object moving in a straight line is accelerated if it speeds up or slows down. Motion on a circle is accelerated even if the speed is constant, because the direction is continually changing.
Time graph plots acceleration values on the y-axis, and time values on the x-axis. In this graph, the acceleration remains constant at 2.0 m/s/s for 10 seconds. Acceleration is defined as a change in an object's velocity, so if an object is accelerating at 2 m/s/s, then every 1 second, the object will gain 2 m/s.
