## Where will the hour hand of a clock stop if it start?

If the hour hand of a clock starts from **7** and turns through 2 straight angles, then it will stop at 7.

## Where the hour hand of a clock stop if it starts from 6 and makes 3/4 of a revolution?

(d) starts at 5 and makes 3/4 of a revolution, clockwise? rotate by 180 degree and hence, it will stop at 6. rotate by 180 degree and hence, it will stop at **8**.

## What is the angle made by the hour hand of the clock when it moves from 5 to 7?

Since a circle consists of 360 degrees from the center, each number is space 112⋅360=30 degrees from each other. Thus, for the hour hand to move from 5 to 7, it moves a total of (7−5)⋅30=**2⋅30=60 degrees**.

## Where will the hand of a clock stop if it starts from 6 and turns through 1 right angle?

SOLUTION: i) if the hour hand starts from 6 and turns through one right angle it will reach **9**.

## Where will the hand of a clock stop if kavya starts from 5 and makes?

Answer: Answer: In one complete revolution the clock hand **returns back to the same position**. So, if it starts at 12 then it would again stop at 12, if it starts at 2 it would again stop at 2 and if it starts at 5 it would again stop at 5.

## What is the measure of 3 by 4 of a revolution?

The measure of 3/4 of revolution is **270°**.

## How many right angles does 3 6 have?

The hour hand of a clock revolves by 360° or 4 right angles in one complete round. (a) The hour hand of clock revolves by 90° or **one right angle** when it goes from 3 to 6. (b) The hour hand of clock revolves by 180° or 2 right angles when it goes from 2 to 8.

## How many right angles are in one hour?

If you switch to a rotating coordinate system in which the hour hand stands still, then the minute hand makes only 11 revolutions, and so it is at right angles with the hour hand **22 times**. In a 24 hour day you get 2×22=44.
