A stone tied to the end of a string 100 cm long is whirled in a horizo

1.	A stone tied to the end of a string 100 cm long is whirled in a horizontal circle at a constantspeed. If the stone makes 10 revolutions in 20 s, the angular velocity of the stone is rad/sIf the string is made 80 cm long, the angular velocity will(increase, decrease,remain the same)
Answer» Answer: 1800 rad/s Explanation: Perimeter of revolution of 100 cm STING = (2π 100) total angles for 10 revolution = 218010*100 = 360000 rad ANGULAR velocity= (360000/20)= 18000 rad/s If the string is made 80 cm LONG , the angular velocity will same because then revolution of the sting increases.

Answer»

Answer:

1800 rad/s

Explanation:

Perimeter of revolution of 100 cm STING

= (2*π *100)

total angles for 10 revolution

= 2*180*10*100 = 360000 rad

ANGULAR velocity= (360000/20)= 18000 rad/s

If the string is made 80 cm LONG , the angular velocity will same because then revolution of the sting increases.
