Answer:
808.25 seconds
Explanation:
From the relation,
If t = time
v = velocity
l = length
The current density, J, of a charge is given by:
Where number of charge carriers per unit volume n = 8.49 * 10²⁸
Charge of the electron, q = 1.6 * 10⁻¹⁹
Cross sectional area of the wire, A = 0.21 cm² = 0.000021 m²
Equating (1) and (2)
Since t = l/v.......(3)
Put the formula for v into equation (3)
t = 808.25 seconds
Answer:
It doesn't allow plants and crops to grow also some animals take them to be food so they die which wipes out the population of animals and plants
