Answer:
Maximum speed of the car is 17.37 m/s.
Explanation:
Given that,
Radius of the circular track, r = 79 m
The coefficient of friction, 
To find,
The maximum speed of car.
Solution,
Let v is the maximum speed of the car at which it can safely travel. It can be calculated by balancing the centripetal force and the gravitational force acting on it as :


v = 17.37 m/s
So, the maximum speed of the car is 17.37 m/s.
The blue color of the sky is the
result of scattering. The answer is letter B. it is specifically called the
Rayleigh scattering. This blue color is the result of the incoming rays of the Sun
into the earth’s atmosphere. It has he lowest wavelength which as we all see is
the blue spectrum of light.
