From the point of view of the northern hemisphere:

The sun starts out the year at the Spring equinox, March 21,
Right Ascension 0, Declination 0.

3 months later, Summer solstice, June 21
RA = 6 hours, Dec. = +23.5°

3 months later, Fall equinox, September 21,
RA = 12 hours, Dec. = 0

3 months later, Winter solstice, December 21,
RA = 18 hours, Dec. = -23.5°

The resistance between 2 points in an electrical circuit is 1.1 Ω. What additional resistance

valentinak56 [21]

Answer:

the new resister is 11 ohms.

Explanation:

Set it up like this.

1/x + 1/1.1 = 1 Subtract 1/1.1 from both sides

1/x = 1 - 1/1.1

1 - 1/1.1 = 1/11

1/x = 1/11 Cross multiply

11 = x

If 1/11 bothers you, you could do it it another way.

1 - 1/1.1 = (1.1 - 1 ) / 1.1 = 0.1 / 1.1 Multiply top and bottom by 10

0.1*10/(1.1 * 10 ) = 1 / 11

Gelneren [198K]

The process by which the heat energy is transmitted between the atoms or molecules is known as conduction.

Explanation:

Conduction is the transfer of heat through the material that are caused by temperature gradient with the material ends in heat flux. The heat transfer done by movement and mixing of a fluid is known as convection.

If a fluid is taken and it is kept as stationary. If there is a temperature gradient across that fluid, there would be transfer of heat that occurs in the fluid. It is negligible when compared to convective heat transfer.

Because of the heat transfer from solid to solid, density of liquid changes and start to move in upward direction due to low density. This type of motion is known as convection currents.
