How is thermal energy from the sun distributed on Earth ?
Mrac [35]
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.

PLEASE HELP!! URGENTT!
oksano4ka [1.4K]

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

A researcher measures the thickness of a layer of benzene (nn = 1.50) floating on water by shining monochromatic light onto the
baherus [9]

Answer:

The minimum thickness is t= 8.75*10^{-8} m

Explanation:

generally the equation for thin film interference is mathematically represented as

            2nt = (m + \frac{1}{2} )  \lambda

Where t the  thickness  

           m is any  integer

            n is the refractive index of the film

            \lambda is the wavelength of light

Since we are looking for the thickness we make t the subject of the  formula

          t = \frac{(m+ \frac{1}{2} ) \lambda}{2n}

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

   Substituting values

                    t = \frac{(0 +\frac{1}{2}) 8525*10^{-9} }{2 *1.5}

                       t= 8.75*10^{-8} m
