Answers
Answer:
1) Liquid solution: Oceans
2) Gaseous Solution: Air
3) Compound: Water
4) Colloid: Cloud
5) Element: Oxygen
Explanation:
Solutions are those mixtures which have uniform composition. The size of solute is around 1 Angstrom hence, the particles of solutes can not be seen and the interactions make the overall solution transparent.
Compounds are those substances which are formed chemically by the reaction of two different elements like,
O₂ + 2 H₂ → 2 H₂O
Colloids are also mixtures but these are intermediate between true solutions and suspensions. Also, the solute size is greater than that of solute size in solutions and is about 10 Angstrom. Examples include Clouds, Fog, Moist, Aerosol sprays e.t.c.
Elements are those substances which either are made up of single atoms like noble gases or are molecules made up of same elements like O₂, H₂, Cl₂, N₂ e.t.c.

or we can just add up the energy budget.
-- Gravitational potential energy = (mass) (grav accel) (height above something)
-- 29 m above the net, his potential energy is (81 x 9.8 x 29) = 23,020 joules
-- All the way down, air resistance exerts 100 N of force against him.
The energy burned up by air resistance is the work done = 100 x 29 = 2,900 joules.
-- The energy he has left when he hits the net is (23,020 - 2,900) = 20,120 joules.
-- When he hits the net, all of his energy is kinetic energy . . . (1/2) (m) (v²)
(1/2) (m) (v²) = 20,120
(40.5) (v²) = 20,120
v² = 20,120 / 40.5
v = square root of (20,120 / 40.5) = 22.3 meters per second (about 50 mph)

The wavelength of the visible range of the electromagnetic spectrum lies between .
Further Explanation:
The Electromagnetic spectrum is the complete range of the electromagnetic radiation which expresses all the radiation starting from the Gamma rays to the radio waves. The electromagnetic spectrum is the detailed spectrum that explains all the electromagnetic radiations.
The electromagnetic radiations are the transverse waves which do not require any medium for their propagation. The electromagnetic waves can easily travel through space. All the electromagnetic radiations travel at the speed of light.
The different radiations in the electromagnetic spectrum are as follows:
- Gamma rays
- X-rays
- Ultraviolet rays
- Infrared rays
- Micro waves
- Radio waves
The wavelength and the frequency ranges for the different electromagnetic radiations is as shown in figure attached.
Therefore, the wavelength of the visible range of the light in the electromagnetic spectrum is .

Keywords:
Electromagnetic spectrum, visible light, EM waves, wavelength, 700nm, 400 nm, 7000 A, frequency, gamma rays, transverse waves.
Explanation:
Visible light is a very part of electromagnetic spectrum. We can see the visible region of the electromagnetic spectrum.
The frequency and the wavelength has an inverse relationship.
For example, the red light has large wavelength and low frequency. Violet has a short wavelength and higher frequency.
The frequency range of visible region is from 400 nm to 700 nm.
