# What is the angular speed of minute hand of a smoothly running watch?

Contents

## What is the angular speed of a second hand on a watch think it goes how many revolutions in how many seconds?

There are 2π radians in one complete rotation, and that takes the second hand 60 seconds to complete. 2π /60 = pi/30 radians per second# which is about 0.105 radians per second.

## What is the angular speed of the minute hand of a clock if the minute hand is 5 cm long?

Given: R = 5 cm = 5 × 10−2 m T = 1h = 3600 s For the minute hand of the clock i. The angular velocity is 1.74 × 10–3 rad/s. ii. The linear velocity of the tip is 8.7 × 10–5 m/s.

## Which angular velocity is greater a second hand minute hand and hour hand of a clock?

Solution : The hour hand of a watch takes 12h to complate one rotation i.e. T1=12 hour. And the earth takes 24 hours to rotate once around its axis, i.e. T2=24 hour. i.e., angular speed of hour hand is greater than the angular speed of earth around its axis.

## What is RPM in speed?

CARS.COM — RPM stands for revolutions per minute, and it’s used as a measure of how fast any machine is operating at a given time. In cars, rpm measures how many times the engine’s crankshaft makes one full rotation every minute, and along with it, how many times each piston goes up and down in its cylinder.

## Is the angular acceleration of the second minute and hour hands the same?

Part (g) Is the angular acceleration of the second, minute, and hour hands the same? Pick the most accurate response: 1) Yes. The angular acceleration of each hand is zero.

## What is the final angular velocity of the carousel?

When one person is standing on the carousel at a distance of 1.50 m from the center, the carousel has an angular velocity of 0.600 rad/s. However, as this person moves inward to a point located 0.750 m from the center, the angular velocity increases to 0.800 rad/s.

## What is the angular velocity of minute hand of a clock * 2 points?

Hence, the angular velocity of the minute hand on a clock is π1800rad/s.

## What is the angular separation of minute hand?

Explanation: The distance between each notch on the clock is 6 degrees because there are 360 degrees on the clock, and there are 60 notches total. The minute hand is at notch #20, and so it is 120 degrees from the top.

## What is the ratio of angular speed of minute hand and hour hand of a watch?

The hour hand of a clock covers 30 degrees in 60 minutes. So, the correct answer is option C, ωm:ωh=12:1.
