What is the angular speed of the minute hand of a clock if the minute hand is 5 cm long?
The angular velocity is 1.74 × 10–3 rad/s.
What is the ratio of centripetal acceleration of the tip of the minute and hour hand of a clock if the minute hand is 1.5 times longer than the hour hand?
The ratio of the Centripetal acceleration of the tip of the minute and hour hand of a clock is 216:1. Hope this answer is helpful.
What is the ratio of linear speed for the tip of the hour hand?
The circumference of that circle is 2*Pi*R or 2*3.14159*18 = 113.10cm. So the velocity of the tip of the hour hand is 113.10cm/12hours or 9.42cm/hour.
What is the ratio of angular speed of an hour hand and minute hand of the clock 2 1 3?
The hour hand of a clock covers 30 deg in 60 min or 0.5 deg/min. The ratio of the angular speed of the minute to the hour hand = 6/0. 5=12:1. Was this answer helpful?
What is the ratio of angular velocity of minute hand and hour hand of a clock?
6/0
What is 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 ratio of the angular speeds for the tips of hour and minute hands of a clock if the minute hand is 2.5 times longer than the hour hand?
The ratio of the angular speed of the minute to the hour hand =0.
What is the angular displacement of the minute hand of a clock in 600 seconds?
60 degrees
What is the angular displacement of the hour hand in 30 minutes?
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 minute hand?
Complete answer: Thus, the total angular displacement of the minute hand of the clock is 60 degrees.
Does angular momentum have direction?
Angular velocity and angular momentum are vector quantities and have both magnitude and direction. The direction of angular velocity and angular momentum are perpendicular to the plane of rotation.
Why does angular momentum have a direction?
Because angular momentum is related to angular velocity by L = Iω, the direction of L is the same as the direction of ω. Notice in the figure that both point along the axis of rotation.
What is angular momentum principle?
Principle of conservation of angular momentum states that, If no external torque acts on a system, the total angular momentum of the system remains constant. If I be the moment of inertia of a body about a given axis of rotation and w be its angular velocity, then I w = constant.
