Answer:
v=wavelength ×f
wavelength=v/f=455/655=0.694m
Answer:
In Nanometer- 580 nanaometers
In Meter - 5.8 x 10^-7
The force of attraction for the states of matter, which can be ignored for most part of calculation or observation, is the gases.
<u>Explanation:
</u>
Gases have incredibly less force of attraction. The inter molecular space between the gaseous molecules are so vast that the force of attraction between them is negligible.
And, for a matter of assumption for smooth calculation, factors which are negligibly less can be ignored. And, thus, for most part of science, the attractive force is ignored among the gaseous particles.
Given :
Our weight is 600 Newton on the earth.
To Find :
How far should you go from the center of the earth so that it will be 300 Newton.
Solution :
Acceleration due to gravity at depth d is given by :

At earth surface, mg = 600 N ...1)
At depth d, mg' = 300 N ...2)
Dividing 1) and 2), we get :

Therefore, we should go in the depth of distance half the radius of earth.
