The energy from the light is transferred to the material, causing it to vibrate and absorb the light.
What is energy?
In physics, energy is the quantitative quality that is transmitted to the a body or a physical system, and is discernible in the work performed as well as in the form of light and heat. The law of conservation states that although energy can change its form, it cannot be created or destroyed. Energy is indeed a conserved quantity. The International System of Units' (SI's) joule is the measurement unit for energy (J). A moving object's kinetic energy, a solid object's elastic energy, chemical energy caused by chemical reactions, and the potential energy that an object stores (for instance because of its position inside a field) are examples of common forms of energy.
When light falls upon a material that has a natural frequency equal to the frequency of the light, the light will be absorbed by the material. This is due to resonance, which occurs when the frequency of the light matches the natural frequency of the material. The energy from the light is transferred to the material, causing it to vibrate and absorb the light.

Answer:
A
Explanation:
i feel it is correct
in the sense that it dwpends on the presence of 4different antigens
The cyclist accelerates for 4 seconds.
Explanation:
The motion of the cyclist is a motion at constant acceleration, so we can use suvat equations:
where
s = 64 m is the distance covered
u = 15 m/s is the initial velocity
t is the time
is the acceleration
Substituting into the equation,
Solving the equation for t,
Which gives two solution: one is negative, so we discarde it since it has no physical meaning; the other one is
t = 4 s
which is the answer we were looking for.
