Common questions

What is the speed of the tip of second hand of a clock if its length is 10 cm?

What is the speed of the tip of second hand of a clock if its length is 10 cm?

The speed of the tip of the hand is ……… . v=rω=r(2πT)=10×2π60=π3cm/s.

What is the length of the second hand on a clock?

The length of a second’s hand of a clock is 4 cm.

What is the speed of the tip of the second hand?

Answer Expert Verified. Seconds HAND of watch completes 1 revolution in 60 sec ( 1min). = 1.57 x 10 ^-3 m/s. Therefore , speed of the tip of second’s hand of a watch of length 1.5 cm is 1.57 x 10 ^-3 m/s.

What is the average speed and velocity of the tip of the second hand of a clock of radius 10 cm?

Therefore, Speed of the tip of 10 cm long second hand of a clock is 1.0466 cm/second .

Is the second hand the radius of a clock?

When you said, seconds hand has a length of 10 cm, that means the seconds hand rotates along the circle with a radius of 10cm. So, in 15 seconds, it travels quarter of the circle or 90 degrees.

What is the length of the hour hand?

In this case, the radius is the length of the hour hand, which is stated to be 3 ft.

What is the speed of tip of minutes hand of clock whose length is 7 cm *?

Calculate the speed of tip of minutes hand of a clock, whose length is 7cm. Here, l=r=7cm×10-2m. speed, v=st=2πrT=2×227×7×10-260×60=119×10-4=1.22×10-4m/s.

What is the speed of tip of second hand of the watch of length 1 cm?

30π​cm/s.

What is the relationship between velocity and angular velocity?

READ:   Is feedback a verbal communication?

The greater the rotation angle in a given amount of time, the greater the angular velocity. Angular velocity ω is analogous to linear velocity v. We can write the relationship between linear velocity and angular velocity in two different ways: v=rω or ω=v/r.

What is the diameter of a clock?

Option Two: FRAMED CLOCKS DIAMETER OF UNFRAMED Wall Clocks: 12 inch clocks are 12 inches diameter, 18 are 18 inches diameter, 24 clocks are 24 inches diameter etc! Make sure to get a battery that is over 1.3v for the large wall clocks. The larger hands take a lot of energy so a better battery will last longer.

What is the distance of the second hand on a clock?

Distance is the actual distance traveled through the path taken. And Displacement is the distance in the shortest path. The second hand on a clock is 8 cm long. What is the distance the tip of the second hand travels in 10 minutes?

What is the speed of the tip of 10 cm long second hand?

READ:   How do I get around Xbox one communication ban?

Here distance will be the circumference of the circle that second-hand makes in one complete revolution. Therefore, Distance = 2 * pi * r (circumference) Now, the time it takes to complete one full revolution by second hand = 60 seconds Therefore, Speed of the tip of 10 cm long second hand of a clock is 1.0466 cm/second .

How many degrees does a second hand travel in 15 seconds?

When you said, seconds hand has a length of 10 cm, that means the seconds hand rotates along the circle with a radius of 10cm. So, in 15 seconds, it travels quarter of the circle or 90 degrees.

How many revolutions does the second hand make in one minute?

The second hand makes 10 revolutions, one for each minute. The circumference of the circle made by the tip of the second hand is 2πr (if you’d paid attention in class, you’d know this) where r (for radius) is the length of the second hand. The arithmetic is left as an exercise for the questioner.
