As 1 km = 1000 m = 1000,00 cm,
So, 1 cm = (1/1000,00) km
1 hour = 60 × 60 s = 3600 s
So, 1 s = (1 / 3600) hour
The light travels at a speed of 
.
In kilometer/hour,
Answer: Their u go i found it their was about 3 pages i did not no what pages u had to do.
Explanation:
Answer:
3.834 m/s
Explanation:
h = 0.750 m
vx = 5 m/s
Let the initial vertical velocity is vy.
Final vertical velocity is zero
use third equation of motion along y axis
v^2 = vy^2 - 2 x g x h
0 = vy^2 - 2 x 9.8 x 0.75
vy^2 = 14.7
vy = 3.834 m/s
Neutrons < Cosmic radiation < Gamma rays < beta particles < Alpha particles
Explanation:
Alpha particles are the most energetic of the nuclear radiations produced in nuclear reactions.
Neutrons are radiations with no charges on them. They are the lowest radiation in terms of energy.
Cosmic radiation are energetic radiations usually produced when solar radiation interacts with the atmosphere.
Gamma ray is a form of electromagnetic radiation with no mass and charge.
Beta particles are of two types. The negative and positive beta particles. Negative beta particles are called negatrons and they carry negative charges while positrons carry positive charges.
Alpha particles are similar to Helium atom,they are the most energetic of all the radiations.
