What is speed of tip of seconds hand of clock if its length is 10cm?
The speed of the tip of the hand is ……… . v=rω=r(2πT)=10×2π60=π3cm/s.
What is the angular displacement of second hand in 10 seconds?
A second hand makes a complete revolution (360 degrees) in 60 seconds, so it displaces 6 degrees for every second (360/60 = 6). So in 10 seconds, it will make a displacement of 60 degrees (6 x 10= 60 degrees).
What is the angle described by hour hand in 10 minutes?
10 minutes is 1/6 of an hour so the hour hand has also moved 1/6 of the distance between the 3 and the 4, which adds 5° (1/6 of 30°). The total measure of the angle, therefore, is 35°.
What is the area swept by the minute hand in 10 minutes?
The area swept by the minute hand in 10 minutes is 104. 76 cm².
What is the speed of the tip of the hand?
1 Expert Answer It takes the tip 60 seconds to go all the way around the circle, so the tip moves 32π cm in 60 seconds, for a speed of 32π/60 = 8π/15 cm/sec. This is approximately equal to 1.68 cm/sec.
How do you find the angular displacement of a clock?
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. Angular displacement is generally calculated in radians, but it can also be expressed in degrees or revolutions per second.
What is angular displacement in radian of a second hand of a clock in 15 seconds?
=2π60×15=π2rad.
What is the length of the minute hand of a clock?
The arithmetic is left as an exercise for the questioner. The minute hand of a clock is 12 cm long and the hour hand is 10 cm long. What is the distance between the tips of the hands at 9:30 PM?
How do you find the distance between the clock hands?
Find the distance between the clock hands when the time is . The hour hand is mm and the minute hand is mm (you do not have to measure tip to tip). The first thing you will have to do is determine the degrees that the hour hand is away from the minute hand.
How many degrees does a second hand travel in 15 seconds?
When you said, seconds hand has a length of 10 cm, that means the seconds hand rotates along the circle with a radius of 10cm. So, in 15 seconds, it travels quarter of the circle or 90 degrees.
How far does the hour hand travel in minutes?
What the minute hand travels in an hour, the hour hand travels in five minutes, so halfway through five minutes is added to 15 minutes puts the hour hand at 17.5 minutes. To find the distance we subtract 17.5 from 30: Therefore A’s hands have a 12.5 minutes distance.
