What fraction of a clockwise revolution does the hour hand of a clock turn through when it goes from 4 to 10 and 5 to 2?
3/4 revolution is covered when the hour hand goes from 1 to 10 in the clockwise direction.
What fraction of a clockwise revolution does the hour hand of a clock turn through when it goes from 12 to 3 *?
Therefore the fraction covered by the clockwise movement of the hour hand from 12 to 9 is 34. Note: 1. Every fraction has a numerator that equals the number of parts we have and a denominator equaling the total number of parts in a whole.
What fraction of a clockwise revolution does the hour hand of a clock turn through when it goes from 7 to 9?
(b) the situation 4 to 7 on the clock, the hour hand turns through 1/4 of a revolution, clockwise. (c) the situation from 7 to 10 on the clock, the hour hand turns 1/4 of a revolution, clockwise. (d) the situation from 12 to 9 on the clock, the hour hand turns 3/4 of a revolution, clockwise.
How many revolutions will a clock hand make if it moves from 3 to 6?
The hour hand of clock revolves by 360 degree or 4 right angles in 1 complete round. (a) The hour hand of a clock revolves by 90 degree of 1 right angle when it goes from 3 to 6.
How many right angles are formed when hour hand of a clock moves from 2 to 8?
2 right angles
The hour hand of a clock revolves by 180 degree of 2 right angles when it goes from 2 to 8. Hence, two right-angles.
What angle measure does the hour hand of a clock turn through when it goes from 12 to 9?
Answer: The hour hand of a clock turns through an angle of 270 degrees when it goes from 12 to 9.
How many right angles does the hour hand of a clock turn when it moves from 6 to 12?
three right angles
So, hour hand turned by three right angles. (f) Here, the hour hand move from 12 to 6. It starts from 12 and covers digits 1, 2, 3, 4, 5 and 6.
How many revolutions does the hour hand make in a day?
In one hour the hour hand makes 1/12 revolution while the second hand makes 60 revolutions. So, in 24 hours, the hour hand makes (24*1/12 = 2) revolutions and the second hand goes round (24*60=1440) times.
What fraction of a revolution have you turned through if you stand facing north and turn clockwise to face West?
If one is facing north , and turns clockwise to face west he will have turned through 3/4 fraction. There are four directions , One will turn from north to east and completes 1/4 th fraction.
What does the angle made by the hour hand of the clock looks like 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.
How many right angles are formed when hour hand of a clock moves from 1 to 10?
one right angle
(d) 10 to1 The hour hand of a clock revolves by 90 degree of 1 right angle when it goes from 10 to 1. Hence, one right angle.
What angle measure does the hour hand of a clock?
