Answer:
Work is done in moving a charge of 2 coulomb across two points having a potential difference of 12 volt is 24 joule .
Explanation:
The wavelength of a wave (λ) is given by λ

where c is the wave speed and f is the frequency
- At pole the gravitation is more than that of equator .
And according to newtons second law
Force=Mass×Acceleration
And

- Hence force varies directly with acceleration hence weight will be more .
Answer:
3. increases with an increase in temperature.
Explanation:
The air more water vapor at higher temperatures because at higher temperatures the air expands and the inter-molecular space increases so the room for water molecules increases.
Warm air keeps the water molecules warm and prevents them from condensing.
The air can hold the moisture only upto its saturation quantity after which the precipitation occurs in the form of rain, snow, hail, sleet etc.
