Answer: It has a range of visible and invisible forms of radiation.
Explanation:
Electromagnetic wave is defined as the wave which is associated with both electrical and magnetic component associated with them. They can travel in vacuum as well and travel with the speed of light i.e 
The electromagnetic radiations consist of radio waves, microwaves, infrared ,Visible , ultraviolet, X rays and gamma rays arranged in order of increasing frequency and decreasing wavelengths.
Only visible light is visible to naked eyes.
The relationship between wavelength and frequency of the wave follows the equation:
where,
= frequency of the wave
c = speed of light
= wavelength of the wave
From the above relation, it is visible that wavelength and frequency follow inverse relation. For increase in wavelength, the value of frequency decreases and vice-versa.
<h2>Answer: increases </h2><h2 />
Explanation:
The expression for an Ideal Gas is:
Where:
is the pressure of the gas
is the volume of the gas
the number of moles of gas
is the gas constant
is the absolute temperature of the gas
As we can see, there is a <u>direct proportional relation between the temperature and the pressure</u>, which means that if the temperature increases the pressure of the gas increases as well.
However, it is important to note this is fulfilled if and only<u> if the volume of the container where the ideal gas is, remains constant.</u>
Answer:
Option E
Explanation:
Red Dwarfs are abundant throughout the universe. They are stable and considered to be candidates for exoplanets capable of sustaining life.
White Dwarfs are stars in the last phase of their evolution. A red giant of under 10 solar masses that has used its critical elements will shed its outer layers, stats to collapse under its own gravity and shrink to a white dwarf. They longer experience nuclear fusion.
The two bodies we are most interested in are Giants and Supergiants but it is important to look at others.
Neutron Stars are collapsed giants that had an original mass many times that of the Sun and explode as a supernova leaving a neutron star. These stars are compressed so much that they are composed entirely of neutrons, parts of the atom without electrical charge. This is the equivalent of the size of the Sun in the same area as a city or the human population on Earth fitting inside an area the size of a sugar cube.
Answer:
Vf = 21.5 [m/s]
Explanation:
To solve this problem we must use the following kinematics equation:
where:
Vf = final velocity [m/s]
Vi = initial velocity = 0
a = aceleration = 4.3 [m/s^2]
t = time = 5 [s]
Now replacing:
Vf = 0 + (4.3*5)
Vf = 21.5 [m/s]
