The length of a simple pendulum is determined by measuring the length of thread l by meter scale and radius of bob r by Vernier callipers. The effective length L is obtained by adding the two, i.e., L=l+r.
What is used to measure the diameter of a pendulum bob?
Procedure: Measure the diameter of the pendulum bob with a micrometer caliper.
What instrument can be used to measure the period of a pendulum?
Measure the swing period with a stopwatch. Or, in fact, several periods and do some division. The most accurate way to start and stop the watch is at the bottle of the swing, when it is moving fastest. Use a graticule or a mirrorscale.
What is the instrument used to measure the diameter?
Calipers are typically used to measure internal (or external) diameters, or other measurements where a flat ruler would be inadequate or wouldn’t fit. (Micrometers are also an option for thicknesses, depths, and sometimes outer diameters.)
Which instrument is used to measure the diameter of a spherical metal Bob?
A spherometer is an instrument used for the precise measurement of the radius of curvature of a sphere or a curved surface.
What instrument measures thickness?
A vernier caliper is a high-precision measurement tool that can be used in multiple types of measurements. It can measure thickness, diameter and even inside diameter for pipes.
What instrument is used to measure the internal diameter of a test tube?
=> Vernier callipers is most suitable to measure the internal diameter of test tube..
How do you measure the period of a pendulum?
The formula for the period T of a pendulum is T = 2π Square root of√L/g, where L is the length of the pendulum and g is the acceleration due to gravity.
How do you measure the period of a pendulum more accurately?
My physics textbook states that in measuring the time period of a pendulum it is advised to measure the time between consecutive passage though the mean position in the same direction. This results in better accuracy than measuring time between consecutive passage through an extreme position.
Is an instrument used to measure the diameter of wires?
The screw gauge is an instrument used for measuring accurately the diameter of a thin wire or the thickness of a sheet of metal.
Why are gauges used?
gauge, also spelled gage, in manufacturing and engineering, a device used to determine, either directly or indirectly, whether a dimension is larger or smaller than another dimension that is used as a reference standard.
Which tool is used for measuring the thickness of sheet metal?
sheet metal gauge tool
A sheet metal gauge tool is used to measure metal thickness, and show both the gauge number as well as the thickness of the metal in thousandths of an inch. Different gauge thickness applies to different metals.
Which of the following instrument is used to measure thickness of wire?
screw gauge
The screw gauge is an instrument used for measuring accurately the diameter of a thin wire , thickness of a sheet of metal or the sheet of paper.
Which instrument is used to measure the internal diameter of a pipe with a single measurement or single step?
Digital caliper-jaw micrometers are used to measure the inside dimensions of holes, tubes, pipes, or grooves, and have jaws that expand and contract. These micrometers are held at a parallel angle to the surface of a hole or bore to measure diameter with contact points on the jaws.
What is pendulum swing?
A pendulum is an object hung from a fixed point that swings back and forth under the action of gravity. In the example of the playground swing, the swing is supported by chains that are attached to fixed points at the top of the swing set.
What is the velocity of bob of simple pendulum?
The velocity of Bob is 1.4m/s
Kinetic energy of the bob at mean position = Potential energy of the bob at the highest position. Thus, the velocity of the bob is 1.4 m/s.
How do I measure my period?
Starting on the first day of your period, start counting. The day before your next period is the last day of your menstrual cycle. That’s when you stop counting. That’s how many days you had in your menstrual cycle that month.
How do you measure the diameter of a wire?
Make a small mark on the wire with a lead pencil (or any mark or ink that will transfer to paper). Roll the wire across a piece of paper so that the mark transfers at least twice. The distance between marks is the wires circumference with a ruler. Divide by pi (3.14) and this is the diameter.
