Weathering breaks down, erosion moves.
<span>Energy of Photon emitted by heated lithium atom E = 2.961 Ă— 10â’19 J
We need energy for only one mole of photons n = 1
Total photons in one mole = 6.022x10^23 photons / mole
Total Energy = n x h x E => 1 x 6.022x10^23 x 2.961 Ă— 10^â’19
Total Energy = 1.783x10^5 J</span>
Answer:350.92 KJ/kg
Explanation:
Given the process is reversible adiabatic i.e it is isentropic
From steam table
For isentropic process
at
Therefore Work output of the turbine per unit mass of steam is =
=3317.03-2966.11
=350.92 KJ/kg
Convection currents are responsible for circulating hot and cold air in the atmosphere and causing local weather systems. The correct option among all the options that are given in the question is the third option or option "C". I hope that this is the answer that has actually come to your desired help.
Answer:
5 m.
Explanation:
From newton's law of universal gravitation
F = Gmm'/r² ....................... Equation 1
Where F = Force between the giant lead spheres, r = distance between the spheres, mm' = product of their mass, G = universal constant.
Making mm' the subject of the equation
mm' = Fr²/G........................... Equation 2
Given: F = 0.010 N, r = 20 m
Substitute into equation 2
mm' = 0.010×20²/G
mm' = 4/G.
When the gravitational force between them is 0.16 N,
4/G = 0.16r²/G
Making r² the subject of the equation,
r² = 4/0.16
r² = 25
r = √25
r = 5 m.
Thus the distance is = 5 m.
