Aflywheel with a very low friction bearing takes 1.6 h to stopafter the motor power
is turned off. the flywheel was originally rotating at 41 rpm. whatwas the initial rotation rate in radians per second? answer in units of rad/s. how many revolutions does the flywheel make before it stops? answer in units of rev.

(I). The initial rotation rate is 4.29 rad/s.

(II). The revolutions is 3932.

Explanation:

Given that,

Time = 1.6 h

Angular velocity = 41 rpm

(I). We need to calculate the initial rotation rate in rad/s

(II). We need to calculate the revolutions

Using formula of revolutions

Hence, (I). The initial rotation rate is 4.293 rad/s.

(II). The revolutions is 3932.

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.

explanation:

i think the answer would be b
