The unit for a stopwatch is usually in seconds, although sometimes it can be in minutes or hours depending on the model.
A stopwatch is typically a handheld device used for measuring time intervals, while a stop clock refers to a wall-mounted or stationary clock that can be stopped and started to measure time. Both devices can be used to accurately time events, but the design and portability differ between the two.
To calculate the least count of a clock, divide the smallest measurement unit of the clock by the total number of divisions on the scale. For example, if the smallest measurement unit is 0.1 seconds and there are 10 divisions on the scale, the least count would be 0.1 seconds divided by 10, which equals 0.01 seconds.
The unit of damping coefficient is Ns/m, which represents the force required to bring a unit velocity proportional to the damping coefficient to a stop in a unit distance.
To stop your Grandfather clock from running fast, you may need to adjust its pendulum length. Try lengthening the pendulum rod to slow down the clock's timing. It's recommended to make small adjustments at a time and monitor the clock's accuracy over a few days. If needed, seek professional help from a clockmaker or horologist.
To turn off the chimes on a grandfather clock, you typically need to stop the clock from chiming at the specific times by adjusting the chime selector lever. This lever is usually located inside the clock case near the movement mechanism. Move the lever to the silent position to mute the chimes. Consulting the clock's manual or contacting a professional for assistance may be necessary if you are unsure about how to turn off the chimes.
