Complete Question:

On a circular race track with a radius of 3.23 km, a certain road car set a speed record of 372 km/h. What was the car's centripetal acceleration?

Centripetal acceleration = 3.306 m/s²

Explanation:

Given the following data;

Radius, r = 3.23 km to meters = 3.23 * 1000 = 3230 m

Velocity = 372 km/h to meters per seconds = 372*1000/3600 = 103.33 m/s

To find the centripetal acceleration;

Centripetal acceleration = velocity²/radius

Centripetal acceleration = 103.33²/3230

Centripetal acceleration = 10677.09/3230

Centripetal acceleration = 3.306 m/s²

- measure reactants precisely. ( first choice)

- stir to the reaction take place. ( second choice)

- wait patiently until the reaction completes. ( fourth choice)

- make sure to recover as much copper as possible. ( last choice)

when cloud cover increases then the suns ray's which provides the earth with light and warmth gets covered due to the due to the suns ray's being blocked, the temperature in that region

therefore to conclude i would like to say that,

=more the cloud cover, the lesser the
