Answer:
The correct option is;
Light energy, which shines on the area around the fire
Explanation:
From the given figure the flame is visible, as the translucent region which shows that the heat from the fire causes flammable organic (carbon containing) vapors to rise and as the vapors get ignited to burn, the heated carbon atoms including the other atoms present in the burning vapor emit light energy due to their incandescent (emitting light when heated) nature, in the same manner an incandescent electric bulb produces light.
Light energy is the visible form of electromagnetic radiation that consists of packets of electromagnetic energy called photons which are emitted by the atoms of a heated incandescent material.
Explanation:
The kinetic energy is basically the energy possesses by virtue of a body's motion
1. The truck moving to the quarry
let the mass be x
and the velocity is given as 20m/s
we know that the kinetic energy is given as
KE=1/2mv^2
KE=1/2(x)*20^2
KE=1/2(x)400
KE=200x
2. The truck leaving to the quarry
let the mass be 2x
and the velocity is given as 20m/s
we know that the kinetic energy is given as
KE=1/2mv^2
KE=1/2(2x)*20^2
KE=1/2(2x)400
KE=400x
From the analysis the kinetic energy is a function of mass, doubling the mass doubles the kinetic energy

Force vectors, use Pythagoras to get resultant force: sqrt ((30^2 + (40^2)) = 50m/s
