The angular velocity of the hour hand of a clock = 30 deg/60 min = 30 deg/hr = 0.5 deg/min = 0.008333 deg/sec. Angular velocity is ratio of angle moved to time taken. In one rotational angle moved will be 2π radian and time will be equal to time period T.

## What is the angular velocity of the hour of a clock?

Answer: the answer is π/21600 rad /s.

## What is the angular velocity of hour hand and minute hand of a clock?

So, the correct answer is option C, ${omega _m}:{omega _h} = 12:1$. Note: It is important to note that $360$ degrees make a complete circle. Here, the minute hand covers the whole complete circle in $60$ minutes but the hour hand covers just $30$ degrees in $60$ minutes.

## How do you calculate angular velocity?

Angular velocity is the rate of change of the position angle of an object with respect to time, so w = theta / t, where w = angular velocity, theta = position angle, and t = time.

## What is the angular displacement of minute hand in 20 minutes?

What is the angular displacement of the minute hand of a clock in 20 minutes? (Ans. 27°, 120°)

## What is the time between 9 and 10?

To be together between 9 and 10 o’clock, the minute hand has to gain 45 minute spaces. 55 minute spaces gained in 60 minutes. The hands are together at 49 (1/11) minutes past 9. Hence, the correct answer is 49 (1/11) minutes past 9.

## What is angular velocity example?

It is less common than linear velocity since it only concerns objects that are moving along a circular path. For example, a roulette ball on a roulette wheel, a race car on a circular path, and a Ferris wheel are all examples of angular velocity.

## How do you find the angular velocity of Class 11?

Angular velocity & its relation with linear velocity

- Average angular velocity = ΔΘ/Δt.
- Instantaneous angular velocity, ω = dΘ / dt.
- v = w r , where v – linear velocity of particle moving in a circle of radius r.
- All parts of a moving body have the same angular velocity in pure rotation motion.

## How do you calculate velocity?

To figure out velocity, you divide the distance by the time it takes to travel that same distance, then you add your direction to it. For example, if you traveled 50 miles in 1 hour going west, then your velocity would be 50 miles/1 hour westwards, or 50 mph westwards.

## How do you find the angular displacement of the minute hand?

The formula is as follows: θ=lr , where angular displacement is given by the length of the arc divided by the radius of the circle.

## What is the angular displacement of the minute hand in 40 minutes?

Answer: Thus, the total angular displacement of the minute hand of the clock is 60 degrees.

## What is the angular displacement of minute hand?

It is simple: In 60 minutes, the minute hands makes a full revolution of 360 degrees. So in 20 minutes it revolves one third, or 120 degrees. It is simple: In 60 minutes, the minute hands makes a full revolution of 360 degrees. So in 20 minutes it revolves one third, or 120 degrees.
