Answer:
It will go 96 times around the track.
Explanation:
Given that,
Distance covered by the race car, d = 765 km
Radius of the circular sprint track, r = 1.263 km
Let n times did it go around the track. It is given by :
C is the circumference of the circular path, 
Approximately, n = 96
So, it will go 96 times around the track. Hence, this is the required solution.
The frequency of the waves are 0,5
This is because the frequency of the wave is calculated by dividing the speed by the wavelength.
A Electric Discharge is the release and transmission of electricity.

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
