The Coulomb's force acting between two charges is
where
is the Coulomb's constant, q1 and q2 the two charges, and r the distance between them.
Using
, we can find the distance between the two charges when the force is F=19.2 N:
Tectonic plates under the ground ,either go on top of each other or crash.
Answer:
179 degree
Explanation:
Solid copper will lose heat to warm up and melt ice . Since all the ice has not melted so final temperature of mixture will be zero.
heat gained by ice to reach temperature of zero degree
= mass of ice x specific heat of ice x rise of temp
= 2 x 2093 x 16 = 66976 J
Heat gained to melt 1.1. kg of ice
mass x latent heat of ice
1.1 x 334000
= 367400
total heat
= 367400 + 66976
=434376
Heat lost by copper
= 6.3 x 385 x T
where 385 is specific heat of copper and T is initial temperature
heat lost = heat gained
6.3 x 385 T = 434376
T = 434376 / (6.3 x 385)
= 179 degree .

Answer:
d = 
Explanation:
This comes from diffrection pattern equation used to locate fringe pattern, i will explain every variable in it here.
n = order of fringe = 0 1 2 3 .. and negative integars as well.
d is sacing between slits.
Theta = angle at which light-Ray is directed towards fringe.
It appears that the distance between consectice fringes would same as the distance between two slits 'd'.
therefore calculating that distance should give us the distance between two fringe patters.
Note we don't use transversal seperation distance here.
