## What is the angular displacement of the minute hand on a clock after 30 minutes have passed?

Since the minute hand would make one rotation in 60 minutes, it would make **1/2 rotation** in 30 minutes.

## What is angular displacement of minute hand of a clock in 40 sec?

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

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

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**.

## What is the angular displacement of the minute hand of a clock after one full day?

2π⋅112=**π6rad** so the minute’s hand shall see an angular displacement of π6 radians.

## 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, ω**m:ωh=12:1**.

## What is the angular displacement of the second hand of a wall clock in one second?

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 position in radians of the minute hand of a clock at 3 30?

The angular position in radians of the minute hand of a clock at 3:30 is **4.** **71 rad**.

## What direction is angular acceleration?

Angular acceleration, also called rotational acceleration, is a quantitative expression of the change in angular velocity that a spinning object undergoes per unit time. … The direction of the angular acceleration vector is **perpendicular to the plane in which the rotation takes place**.

## Why is circular motion acceleration?

Because velocity is a vector quantity (that is, it has both a magnitude, the speed, and a direction), when a body travels on a circular path, **its direction constantly changes and thus its velocity changes**, producing an acceleration. The acceleration is directed radially toward the centre of the circle.

## How much is the angular velocity in radians per hour of a geostationary satellite?

For example, a geostationary satellitecompletes one orbit per day above the equator, or 360 degrees per 24 hours, and has angular velocity ω = 360 / 24 = 15 degrees per hour, or **2π / 24 ≈ 0.26 radians per hour**.
