Answer:
Photons
Explanation:
I just know
Discrete packets of kinetic energy in light are called photons. Photons are fundamental particles of light and electromagnetic radiation. The correct answer is photons.
Photons are fundamental particles of light and electromagnetic radiation. They carry energy in discrete quantities, known as quanta or packets, and exhibit both wave-like and particle-like properties.
The energy of a photon is directly proportional to its frequency, and inversely proportional to its wavelength. When light interacts with matter, it can transfer its energy to the particles it interacts with, leading to various phenomena such as absorption, reflection, and emission.
Therefore, Discrete packets of kinetic energy in light are called photons.

When light reflects from a surface, there is a change in its intensity. Thus, the correct option is C.
What is Light intensity?Light intensity is also known as luminous intensity. It is the amount of light which is falling on a surface over any given square foot or square meter in size. Light intensity can be measured in terms of lumens per square foot (foot candles) or lumens per square meter (lux).
Light intensity is affected by various factors such as surface on which the light rays strike, the medium, reflection, and the refraction of light.
When a ray of light reflects from a surface, there is a change in the intensity of light and also the speed of light in that medium.
Therefore, the correct option is C.

A. They have longer wavelengths and less dangers.
B. They have lower frequencies and more energy.
C. They have shorter wavelengths and less dangers.
D. They have higher frequencies and more energy.
Answer:
A. Longer wavelengths and less dangers
Explanation:
Radio waves are at the lowest end of the EM spectrum, they have the longest wavelength of any other EM waves, the lowest energy and, accordingly, the lowest frequency;
Their low energy and frequency means they pose little risk of harm or danger as they don't get absorbed by human being.

don't answer if u don't know
spammers = reported
Speed= 60 m/s

Answer:
100 m/s

A community plans to build a facility to convert solar radiation to electrical power. The community requires 1.00 MW of power, and the system to be installed has an efficiency of 30.0% (that is, 30.0% of the solar energy incident on the surface is converted to useful energy that can power the community). Assuming sunlight has a constant intensity of 1 000 W/m2, what must be the effective area of a perfectly absorbing surface used in such an installation?
We will find that the effective area that must be used to get the desired power is 3,333.33 m^2
The information we have is:
power needed = 1.00 MW = 1,000,000 watts
Energy of the Sun = 1,000 W/m^2
We know that the system has an efficiency of 30%, then per meter square, the energy converted is:
E = 0.3*1,000 W/m^2 = 300 W/m^2
Now we need to find the area (in meters squared) such that:
A*E = 1,000,000 watts
A*(300 W/m^2) = 1,000,000 watts
A = (1,000,000 watts)/(300 W/m^2) = 3,333.33 m^2
So the effective area that must be used is A = 3,333.33 m^2

How to calculate average velocity with a change in acceleration is not constant.
Regardless of acceleration, average velocity can always be calculated from its definition:
average velocity = (change in position) / (change in time)
It's only when acceleration is constant that the average velocity can be computed using initial and final velocities. Under this condition,
average velocity = (initial velocity + final velocity) / 2
