6 0

Heat is transferred from the sun-warmed surface of the earth to the cooler overlying troposphere via <u>conduction.</u>

<u />

<h3>Heat transfer from earth to atmosphere:</h3>

Conduction, convection, latent heating, and water phase transitions all help to carry heat from the Earth's surface, which has been warmed by the Sun, to the cooler troposphere above.

Latent heat flux is the worldwide transfer of latent heat energy via water and air currents. Here, we demonstrate how air circulation transports latent heat energy horizontally to cooler regions, where it condenses into rain or is deposited as snow, releasing the heat energy that was previously trapped there.

When air is heated from below by sunshine or by coming into contact with a warmer land or sea surface, convection occurs and the air below becomes less dense than the air above.

In a thundercloud there may be electric charges of 45.0 C near the top of the cloud and -45.0 C near the bottom of the cloud. Th

Gala2k [10]

Answer:

The electric force on the top charge is $F=3.44\times 10^6\ N$ .

Explanation:

Given that,

Electric charges in a thundercloud, $q_1=q_2=45\ C$

The distance between charges, d = 2.3 km = 2300 m

Let F is the electric force on the top charge. The electric force is given by the formula as :

$F=\dfrac{kq^2}{d^2}$

$F=\dfrac{9\times 10^9\times (45)^2}{(2300)^2}$

$F=3445179.58\ N$

$F=3.44\times 10^6\ N$

So, the electric force on the top charge is $F=3.44\times 10^6\ N$ . Hence, this is the required solution.

The outer surface of a spacecraft in space has an emissivity of 0.44 and a solar absorptivity of 0.3. If solar radiation is inci

max2010maxim [7]

Answer:

$T=326.928K$

Explanation:

From the question we are told that:

Emissivity $e=0.44$

Absorptivity $\alpha =0.3$

Rate of solar Radiation $R=0.3$

Generally the equation for Surface absorbed energy is mathematically given by

$E=\alpha R$

$E=0.3*950$

$E=285W/m^2$

Generally the equation for Emitted Radiation is mathematically given by

$\mu=e(\sigmaT^4)$

Where

T=Temperature

$\sigma=5.67*10^8Wm^{-2}K_{-4}$

Therefore

$\alpha*E=e \sigma T^4$

$0.3*(950)=0.44(5.67*10^-8)T^4$

$T=326.928K$

a diver is standing on the diving board. the diver has a mass of 85.0kg and has a gravitational potential emergy of 2.50x103 j s

amid [387]

Answer:

Explanation:

Gravitational potential energy of the diver is expressed mathematically as

P = mgh

m = mass of the diver (in kg)

g = acceleration due to gravity (in m/s²)

h = the height of the diver above the water surface.

Given m = 85.0kg, g = 9,8m/s² and P = 2.50x10³ Joules, wecan determine how high the diver is above the water surface bu substituting the given values into the formula;

h = P/mg

h = 2.50x10³/85*9.8

h = 2500/833

h ≈ 3.00m

The diver is 3.00m above the water surface.
