Conduction and convection both require some material substance
to move heat from one place to another, and there's none of that
between the sun and Earth.
The only way for thermal energy to move from place to place with
nothing in between is by the process of radiation, and that's how
it gets here from the sun.
It seems that you have missed the necessary options for us to answer this question so I had to look for it. Anyway, here is the answer. The one that occurs first in the generation of an action potential is that t<span>he membrane depolarizes. Hope this answers your question. Have a great day!</span>
Answer:
120 Newton
Explanation:
Given the following data;
Mass = 12 kg
Angle = 4°
We know that acceleration due to gravity is equal to 10 m/s
To find the minimum force to stop the block from sliding;
Force = mgCos(d)
Where;
m is the mass of an object.
g is the acceleration due to gravity.
d is the angle of inclination (theta).
Substituting into the formula we have;
F = 12*10*Cos(4°)
F = 120 * 0.9976
F = 119.71 ≈ 120 Newton
Answer:
The minimum thickness is 
Explanation:
generally the equation for thin film interference is mathematically represented as

Where t the thickness
m is any integer
n is the refractive index of the film
is the wavelength of light
Since we are looking for the thickness we make t the subject of the formula

m= 0 cause the thickness is minimum at m=0
Substituting values
