Answer:
the answer is A. air is cooler than the ground.
Explanation:
Answer:
Biomass-Total of mass of organisms in a given area/volume
Biofuel-A fuel directly from living matter.
It would be 12W because: 6v is half of 12v so half of 24w would be 12w
Electric field due to a point charge is given by formula

now due to negative charge also the magnitude of electric field will be same
only difference is the direction of field due to negative charge is radially inwards
now we can say that net field due to these two charges is given as



now it is given that distance r is very large than "d" so we can say

<em>so above is the electric field due to dipole</em>
