What is the 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 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 the angular displacement of the minute hand of a clock after 5 minutes?
2π⋅112=π6rad so the minute’s hand shall see an angular displacement of π6 radians.
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 10 minutes?
Thus, the total angular displacement of the minute hand of the clock is 60 degrees.
How much angular distance will be covered by the minute hand of a correct clock in a period of 2 hour 20 minutes?
20 minute =1/3 of an hour=1/3×360=120 degrees.
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 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, ωm:ωh=12:1.
What is the dimensional formula of angular velocity?
Therefore, the angular velocity is dimensionally represented as [M L T–1].
How many degrees does the minute hand move every second?
How many degrees does the minute hand move per second? Therefore the minute hand’s rate is 360 degrees per 20 seconds or 18 degrees per second.
What is the angular frequency of the second hand?
The second hand goes through 2π radians in 1 min, or 2π radian/60 seconds, so ω = π/30 rad. s-1 = 0.03 rad.
How many times the hands of clock meet each other from 11 to 3?
The time between 11 o’clock to 3 o’clock is 4 hours. Therefore the hands of the clock will meet 4 times.
