Which of the following is most precise measurement of the diameter of a wire 1.00 mm 1.0 mm 1.00 1.0 cm?
Answer: The measurement 4.00 mm is most precise because it is measured with an instrument of minimum least count.
What is cm scale?
A centimeter is a metric unit for the measurement of length of objects and small distances. It is written using the symbol cm. It can also be defined as the unit of length in the International System of Units (SI), the current form of the metric system. It is equivalent to 1/100 meters.
How is length measured?
The standard unit of length based on the metric system is a meter (m). According to the length that needs to be measured, we can convert a meter into various units like millimeters (mm), centimeter (cm), and kilometer (km). A kilometer (km), meter (m), and centimeter (cm) are the commonly used units of length.
How many inches is 1 cm in inches?
0.39370079 inches
1 centimetre is equal to 0.39370079 inches, which is the conversion factor from centimeters to inches.
How thick is 1 cm in inches?
Centimeters to inches conversion table
| Centimeters (cm) | Inches (“) (decimal) | Inches (“) (fraction) |
|---|---|---|
| 1 cm | 0.3937 in | 25/64 in |
| 2 cm | 0.7874 in | 25/32 in |
| 3 cm | 1.1811 in | 1 3/16 in |
| 4 cm | 1.5748 in | 1 37/64 in |
Which of the following length measurement is most precise?
The most accurate measure is 0.005 mm. This is because the value has been measured up to three decimal places unlike the other two values.
Which measurement is most precise?
Therefore, 4.00 mm is the most precise measurement.
Is 1 cm half an inch?
Yes. Since an inch equals about 2½ centimeters, a half-inch would equal about 1¼ centimeters. Since 1 inch equals 2.54 cm, a half-inch equals 2.54 / 2 = 1.27 cm.
What is a CM example?
Here are some things that can be measured in centimeters: The waist size of a pair of trousers. Length of the fish caught. The radius of a car’s tires. The distance between a person’s eyes.
What is length size?
Length is a measure of distance. In the International System of Quantities, length is a quantity with dimension distance. In most systems of measurement a base unit for length is chosen, from which all other units are derived.
How do you find the length of a rod at 110°C?
Ans: the length at 110 o C will be 60.09 cm A rod is found to be 0.04 cm longer at 30 oC than it is at 10 oC. Calculate its length at 0 oC if coefficient of linear expansion = α = 2 x 10-5 /oC.
How do you calculate the length of an object at 0 oC?
Calculate its length at 0 oC if coefficient of linear expansion = α = 2 x 10-5 /oC. Given: Difference in lengths = l2 – l 1 = 0.04 cm, Initial temperature = t 1 = 10 o C, final temperature = t 2 = 30 o C, coefficient of linear expansion = α = 2 x 10 -5 / o C.
What would be the length of a metal bar at 110oc?
A metal bar measures 60 cm at 10 oC. What would be its length at 110 oC, α = 1.5 x 10-5 /oC. Given: Initial temperature = t 1 = 10 o C, final temperature = t 2 = 110 o C, initial length = l1 = 60 cm, coefficient of linear expansion = α = 1.5 x 10 -5 / o C.
What is the length of a brass rod and iron rod?
A brass rod and an iron rod are 4 m and 4.01 m respectively at 20 oC. At what temperature the two rods have the same length. α for brass is 18.92 x 10-6 /oC and α for iron is 11.92 x 10-6 /oC.
