What is the speed of the tip of second hand of a clock if its length is 10 cm?

What is the speed of the tip of second hand of a clock if its length is 10 cm?

The speed of the tip of the hand is ……… . v=rω=r(2πT)=10×2π60=π3cm/s.

What is the speed of a second hand clock?

The seconds hand of a clock completes one rotation in 1 minute i.e 60 seconds. Thus, option C is correct. The second hand therefore makes one revolution every minute – that is, 1 revolution per minute (rpm), which is 1/60 of a revolution per second, which is 6 degrees per second.

What is the angular speed of second hand of a clock?

Its angular velocity is π30 radians per second (about 0.105 radians/s.

What is the average speed and velocity of the tip of the second hand of a clock of radius 10 cm?

Therefore, Speed of the tip of 10 cm long second hand of a clock is 1.0466 cm/second .

What is the speed of the tip of the hand?

1 Expert Answer It takes the tip 60 seconds to go all the way around the circle, so the tip moves 32π cm in 60 seconds, for a speed of 32π/60 = 8π/15 cm/sec. This is approximately equal to 1.68 cm/sec.

What is the speed of the tip of second’s hand of a watch of length 1.5 cm?

Seconds HAND of watch completes 1 revolution in 60 sec ( 1min). = 1.57 x 10 ^-3 m/s. Therefore , speed of the tip of second’s hand of a watch of length 1.5 cm is 1.57 x 10 ^-3 m/s.

The Hour hand has an angular velocity of 1/1440 of an RPM. By the way an RPM is 2 Pi radians per minute.

What is the angular velocity of the minute and second hand of clock?

8πrad/s.

Is the second hand the radius of a clock?

When you said, seconds hand has a length of 10 cm, that means the seconds hand rotates along the circle with a radius of 10cm. So, in 15 seconds, it travels quarter of the circle or 90 degrees.

What is the speed of tip of minutes hand of clock whose length is 7 cm *?

Calculate the speed of tip of minutes hand of a clock, whose length is 7cm. Here, l=r=7cm×10-2m. speed, v=st=2πrT=2×227×7×10-260×60=119×10-4=1.22×10-4m/s.
