The slow process of turning of liquids to vapor form is called Evaporation.
The factors which effect the rate of evaporation are:
1. Wind assists evaporation.
2. Heat assists evaporation.
3. Increase in surface area exposed assists evaporation.
4. Dryness assists evaporation.
5. Rate of evaporation depends upon the nature of the liquid.
6. Vapor pressure: if pressure is applied on the surface of a liquid, evaporation is hindered
Answer:
a lens that causes parallel light rays to separate from each other
3.9949X10^9 is the answer
The strength of the magnetic field is
Explanation:
According to Faraday's Law, the magnitude of the induced emf in the coil is equal to the rate of changeof the flux linkage through the coil:
(1)
where
N = 505 is the number of turns in the coil
is the change in magnetic flux through the coil
is the time interval
The coil is rotated from a position perpendicular to the Earth's magnetic field to a position parallel to it, so the final flux is zero, and the magnitude of the flux change is simply equal to the initial flux:
where
B is the strength of the magnetic field
A is the area of the coil
is the angle between the normal to the coil and the field
The area of the coil can be written as
where
is its radius
Substituting everything into eq.(1) and solving for B, we find:
