Apulley of radius 10 cm turns at 6 revolutions per second. what is the linear velocity of the belt driving the pulley in meters per second? . possible answers: . a. 376.99 m/s. b. 1.67 m/s. c. 166.67 m/s. d. 3.77 m/s

We calculate as the linear velocity of the belt driving the pulley as follows:

angular velocity is related to linear velocity by the equation
 
v = wr

where v is the linear velocity, w is the angular velocity, and r is the radius.

v = 6 x 2π x 10
v = 376.99 m/s 

Therefore, the correct answer is option A.

Gamma rays transmit more energy than visible light rays because they possess a greater frequency

E = h x frequency

they are directly proportional
