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 angular displacement in radius of a second hand of a clock in 10 second?
Hence, angular displacement in radian of a second hand of a clock in 10 second is 3πrad.
What is the angular displacement of the second hand of a wall clock in one second?
1 Answer. Its angular velocity is π30 radians per second (about 0.105 radians/s.
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.
What is the angular displacement in radian of a second hand of a clock in 15 seconds?
The angular displacement of a second of a clock in 15 s in SI unit is. =2π60×15=π2rad.
What angle is made by hour hand in 36 sec?
Now imagining that situation (with the second hand not moving at all), the hour hand makes one revolution every 10 seconds. Therefore the hour hand’s rate is 360 degrees per 10 seconds or 36 degrees per second.
How many degrees does the angular displacement of the hour hand of a clock change each hour?
A method to solve such problems is to consider the rate of change of the angle in degrees per minute. The hour hand of a normal 12-hour analogue clock turns 360° in 12 hours (720 minutes) or 0.5° per minute. The minute hand rotates through 360° in 60 minutes or 6° per minute.
What angle is 7 o clock?
The smaller angle between them is 45 degrees. 45 is not divisible by 10. At 7’o clock, the minute hand is at 12 and the hour hand is at 7 i.e. the minute hand is 210 degrees behind the hour hand (going clockwise).
What type of angle is 8 o clock?
At 8 o’clock angle between the two hands is 120 degree. To form an angle of 180, 60 degree more is covered with their relative speed.
What angle is 11 o clock?
Therefore to get the total angle, you must add the 30 degrees from the 10 to 11 plus the 5/6 distance from 11 to 12, and you get 30 degrees + (5/6 * 30) = 30 + 25 = 55 degrees. So the final answer is 55 degrees.
How many 120 degree angles does it take to make a full turn?
Answer: 12 turns. 360 degrees is a full turn, so if you multiply 30 degreed by 12, you go around in a circle.
Can a triangle have 2 90 degree angles?
Can a Triangle have Two Right Angles? Explain. No, a triangle can never have 2 right angles. A triangle has exactly 3 sides and the sum of interior angles sum up to 180°.
Can a triangle have a 0 degree angle?
An angle in a triangle can measure 0 degree. Although a 0 degree angle would make for a very flat triangle, or it could be very thin and pointy, if the top angle is the 0 degree one. A right angle triangle has one angle of 90 degree and other two angle make a combination of 90 degree so as to get a sum of 180 degree.
Can you have a triangle with all the three angles less than 60 degree?
No, a triangle cannot have all angles less than 60°, because if all angles will be less than 60°, then their sum will not be equal to 180°. Hence, it will not be a triangle.
