Answer:
0.45 miles
Explanation:
since, car will be running on the edge of track, distance covered in one lap by car will be equal to circumference of track.\
we will use value of pi as 22/7
Circumference for any circular shape is given by
Hence, in one lap distance will be covered
in 7 laps distance will be covered.
but is given that 7 laps should be equal to 10 miles
so 10 miles will be equal to
Thus, diameter of track will be 0.45 miles to meet the requirement.

Answer:
The number of fission are equal to 1.947 x 10¹⁶
Explanation:
Energy of one fission=208*1.6*10⁻¹³ Joule.
Power of the bulb=120 Watts.
Time t in seconds = 1.5h=5400 seconds
Total energy E=Power* time=120*5400=64.8 x 10⁴ Joule.
Number of fissions N= total energy / energy for one fission
=(64.8 x 10⁴)/(208x1.6x10⁻¹³)
=1.947 x 10¹⁶
