Question

a wheel of a cycle is rotating at 10 revolution per second.after 10 second,it is rotating with a speed of 10 revolution per second.calculate the angle through which this wheel turned in 20second?​

Answer 1

Answer:

1 second

Explanation:

calculate a revolution in 10 second and then multiple in 10 second and then multiple in the same revolution and the same revolution of the world

Answer 2

Answer:

10 seconds

i.e. 10x10=100 revolutions

now 11 to 20 seconds

10x20=200 revolutions

now total angle turned =

(100+200)x360

=1080000
