If a typical smelt weighs 225 g, what is the total mass of pcbs in a smelt in the great lakes? If a typical smelt weighs 225 g,
what is the total mass of pcbs in a smelt in the great lakes? 2.34 × 10-4 g 225 g 234 g 2.16 × 108 g
1 answer:
Answer;
= 2.34 x 10^-4 g pcbs
Explanation;
-A typical smelt has 1.04 ppm of PCB is great lakes.
Therefore;
The amount of PCB in a smelt in great leak can be calculated by multiplying the mass of smelt by the pcbs present in a smelt
= 225 g * ( 1.04/100000)
= 2.34 x10^-4 g pcbs

Answer:
517.5Ns
Explanation:
F=(MV - MU)/t
where MV - MU is the change in momentum,
therefore, MV - MU = Ft
= 345 X 1.
= 517.5Ns
Scientists could investigate this idea by making cathode ray tubes out of different materials to see if the ray was the same.
