What is angular displacement of second hand of a clock 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 angular displacement of the minute hand of a clock in 1 hour?
Explanation: It takes an hour ( 60 minutes) for the minute’s hand to turn a full circle or achieve an angular rotation of 2πrad . There are 605=12 periods of five minutes in an hour. Meaning that the five-minute rotation accounts for 112 of 2π , the rotation of the minute’s hand in an hour.
What is the ratio of angular speed of minute hand and second hand of a clock?
The ratio of angular speed of minute hand and second hands in a watch is 12:1.
What is the angular displacement of the second hand of a wall clock in one second?
2π /60 = pi/30 radians per second# which is about 0.105 radians per second.
What is the value of displacement of the second hand of an analog clock in one minute?
The displacement would be zero because after exactly one minute the second hand tip is in the same position it was in one minute earlier.
What is the angular displacement of second hand in 15 seconds?
=2π60×15=π2rad.
What is the angular displacement of the minute’s hand in an hour?
There are 60 5 = 12 periods of five minutes in an hour. Meaning that the five-minute rotation accounts for 1 12 of 2π, the rotation of the minute’s hand in an hour. 2π ⋅ 1 12 = π 6 lrad so the minute’s hand shall see an angular displacement of π 6 radians.
How long does it take for the minute’s hand to rotate?
It takes an hour ( 60 minutes) for the minute’s hand to turn a full circle or achieve an angular rotation of 2πlrad. There are 60 5 = 12 periods of five minutes in an hour.
What is angular displacement?
Angular displacement is the angle measured in radians and is defined as the shortest angle between the initial and the final points for a given object undergoing circular motion about a fixed point. Angular Displacement is a vector quantity. It has both direction and magnitude.
What is Neena’s angular displacement when she runs around the track?
Therefore, 1) Neena goes around a circular track that has a diameter of 7 m. If she runs around the entire track for a distance of 50 m, what is her angular displacement? According to question, Neena’s linear displacement, s = 50 m. As we know that, d = 2r, so r =7/2= 3.5 m
