Since the factory will be producing 100,000 kilograms of cement, using the relation 1000 kg of cement = 900 kg of CO2, then the factory will be emitting 90,000 kg of CO2 at the same time. To counteract the emission, a tree can remove 6 kg of CO2 per day. Dividing 90,000 kg by 6 kg to know the number of trees, we need 15000 trees to counter the emission. Since 1 acre of land holds 200 trees, we need 75 acres of land to hold the 15000 trees.
Answer:
Joel has the faster speed.

Answer
Given,
Sirius A surface temperature,T = 9400 K
Sirius A luminosity,L = 26 L₀
L₀ is the luminosity of sun.
Radius of sun = 695700000 m
Temperature on sun surface = 5780 K
Luminous intensity is given by:-
