Gravitational Force

The land breeze is a coastal breeze at night blowing from the land to the ocean. It is caused by the difference in the rates of cooling of the land and of the ocean. Once again, the bigger the difference in temperature between the two, the stronger the wind.

So, resistance of Wire 2 is R/4 as radius is half of wire 1, so area would be 4 times of wire 1.

Now for resistance in series. R= R1 + R2.

Therefore, Final R= R + R/4 = 5R/4

Pressure = (Net Force) / (Applied area) = Newton / square meters

Measuring units of pressure are:

. Pascal
. Bar
. Torr
. Pounds per square inch (psi)
. Standard atmosphere (atm).

A galvanic cell is also known as voltaic cell provides electrical energy from the chemical energy.

Energy can be transferred from one system to the other. The rate at which energy is transferred from one system to other system is called POWER. Energy transferred in one second is called a watt.

Pace Count is a way to measure to Ground Distance.

Pace Count is nothing but regular single natural step of about 30 inches long.
