The subscript effect draws a small character below the bottom of the text. On the other hand, superscript draws a character above the top of the text. Underline is character formatting that draws a single line under the text. A strike through draws a horizontal line through the text. A sentence case formats as a sentence with the first word being capitalized and all remaining words beginning with a lowercase letter. <span />
A power plant that is virtually pollution free would be a power plant that does not consume gas, petrol, coal or any of the other resources that may cause pollution.
The virtually pollution-free plant will be mainly depending on natural renewable sources of energy
Examples:
1- geothermal plants (including dry steam plants, binary cycle plants and flash steam plants)
2- solar plant
3- wind turbines
4- water turbines
T = half life period of decay for atoms of element A = 20,000 years
N₀ = initial number of atoms of element A = 10,000 atoms
N = final number of atoms after time "t" = 2500 atoms
t = time of decay = ?
λ = decay constant = ?
decay constant is given as
λ = 0.693/T
λ = 0.693/20,000
λ = 0.00003465 years⁻¹
atoms after decay for time "t" is given as
N = N₀ 
inserting the values
2500 = (10000) 
t = 40,000 years
so correct choice is
B) 40,000 years
