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 same voltage will appear across all resistors in parallel.

<em>Hello, </em>
<h3><u>QUESTION)</u></h3>
According to the second Newton's Law,
<em>✔ We have : F = m x a ⇔ m = F/a </em>
The mass of the object is therefore 200 kg.
Answer: 7.41 m/s
Explanation: By using the law of of energy, kinetic energy of the brick as it falls equals the potential energy before falling.
Kinetic energy = mv²/2, potential energy = mgh
mv²/2 = mgh
v²/2 = gh
v² = 2gh
v = √2gh
Where g = 9.8 m/s², h = 2.80m
v = √2×9.8×2.8 = 7.41 m/s
b. the forces of attraction among them limit their motion.
