In a two column proof does the second column contain a series of deductions?
The second (right-hand) column contains reasons or explanations of the statements given in the first (left-hand) column.
How many degrees in total does the second hand turn in 5 minutes?
well, 360 degrees in a minute. So 360 * 5 = 1800 degrees
What degree of angle is the clock at 1 o'clock?
At exactly 1 o'clock, the hour hand will be at an angle of 30 degrees, and the minute and second hands will be at an angle of 0 degrees.
How many hand shakes would take place if 20 people shake hands once?
First person shakes hands 19 times, second person 18 etc, a total of 190.
Looking at a standard wall clock at the time 630 what is the anglein nearest degrees created by the minute hand and the hour hand?
The hour hand would be at 195 degrees and the minute hand at 180 degrees.
What motion is a second hand watch moves through a complete circle every minute?
That motion is called angular motion. The angular speed of the second hand is 2pi radians per minute.
What is the angular speed of the second hand?
6 degrees/second
The second hand on a watch moves through a complete circle every minute The motion of the second hand on a watch is best described as?
Angular motion.
What is the angular speed of the minute hand in radian per second?
Angular speed = 2*pi radians per 60 seconds = pi/30 radians per second.
What is angular speed of second hand mint hand and hour hand calculated angular velocity?
Second hand . . . 360 degrees per minuteMinute hand . . . 360 degrees per hourHour hand . . . 360 degrees per 12 hours = 30 degrees per hour
What is the angular velocity in radians per second of the second hand of a clock?
The angular velocity of the second hand of a clock is pi/30 radians per second.
How do you find the angular velocity of second hand of a watch?
Angular velocity has units of (angle per time), usually stated in radians per second. (1 whole revolution = 2 pi radians) Assuming the watch is operating properly, the second hand turns once per minute. 1 rev/minute = (2 pi) / (60 seconds) = pi/30radians per second. This is usually good enough for most physicists, but if they demand a number, it's easy to work it out: pi = 3.14159 (rounded) Angular velocity = pi/30 = 0.10472 radians per second. Or if you really want the physicist to take notice, tell him "104.72 milliradians per second".
What is the linear speed of the tip of the second hand of a watch with a length of 15 mm?
The second hand moves 1/60th of a full rotation per second, this is equivalent to 2π/60 radians per second this is known as the objects angular velocity. the equation linking linear velocity and angular velocity is v=rω where v=linear velocity, ω=angular velocity and r=radius and so we must substitute our values in. v=(15/1000)(π/30)=0.00157 m/s which is 1.57mm/s. notice instead of just putting 15 for the radius, i did 15/1000 in order to change it from millimetres to metres, this gave me the linear velocity in m/s.
What is the angular speed of a mint-hand after 5 mint?
Angular speed is angle covered by time taken ... in 60 min the angle covered by minute hand is 360. in 5 min it will be 360/60x 5 it will be 30 degrees or pie/6 time taken is 5 minutes Angular velocity --- pie/6x5 pie/30
Which of the clock arm rotates are constat speed or constant velocity?
Ignoring the fact that some clocks "jump", for example once a second, each of the three arms moves at constant angular velocity. The speed, in this case, is constant; the velocity is not since the direction changes. On the other hand, sometimes people use a vector to describe an angular velocity. Angular momentums add nicely with vector representation.
What are the magnitude of the angular velocity and the angular accelaration of the second hand of a clock?
-- The angular velocity isone revolution/minute = 360 degrees/minute = 6 degrees/second .(2 pi) radians/minute = pi/30 radians per second . -- If the clock is working properly ... not starting, stopping, speeding up, orslowing down ... then the angular acceleration of any of its hands is zero.
What is the third hand on a clock or watch called?
There are 3 hands. The second hand, the minute hand and the hour hand.
