Why do you need to tie a piece of string around the solid while lowering it into a measuring cylinder?
I presume that you are trying to find the volume of an irregular solid. It is usual to tie a piece of thin cotton around the solid prior to lowering it into the measuring cylinder. This is so that you can control the decent of the object, i.e. it is not dropped into the cylinder causing the water to splash out, thus not giving an accuarate value for volume of the solid.

What happens if you lower the frequency of a wave on a string?
Lowering the frequency of a wave on a string will result in a longer wavelength and a lower pitch sound.
What are tools you use while measuring a puddle?
You can use a ruler or measuring tape to measure the diameter of the puddle. A string can also be used by laying it along the edge of the puddle and then measuring the length of the string. Additionally, a depth gauge can help you measure the depth of the puddle accurately.
How can one determine the tension in a string?
To determine the tension in a string, you can use the formula T F L, where T is the tension, F is the force applied to the string, and L is the length of the string. By measuring the force and length, you can calculate the tension in the string.
How to calculate string tension in a musical instrument?
To calculate string tension in a musical instrument, you can use the formula T F L, where T is the tension in the string, F is the force applied to the string, and L is the length of the string between the points where the force is applied. By measuring the force and length of the string, you can calculate the tension.
How does changing the length of the string change the vibration?
The longer the string - the slower the vibration (and lower the note produced). If you shorten the string - it vibrates faster, producing a higher-pitched note,
How do you get the circumference of a cylinder with a string?
Wrap the string around the cylinder, mark where the end of the string touched itself, remove the string, and measure from the end of the string to the mark.
A cylinder 90 cm high has a circumference of 20 cm A string makes exactly 6 complete turns round the cylinder while its two ends touch the cylinder's top and bottom how long is the string in cm?
For the string to wrap around the cylinder and yet do so by "coiling" around the outside of the cylinder from bottom to top, it will need to be 150cm long.
What measuring tool do you need to measure the distance around a basketball?
A piece of string and a ruler or tape measure.
How do you find head circumference?
You can place a string around the head, and then measure the string. Or measure directly with a measuring tape, if you have one that is flexible enough (basically, a measuring tape made up of cloth or something similar).
How do you find the perimeter of a jigsaw puzzle using string?
You can find the perimeter of any planar (flat) object using string by wrapping the string around the outside of the object, noting the point on the string where you return to the starting point, and then measuring the length of that portion of the string.
How do you measure bust without a measuring tape?
If you have a ruler and a piece of string, you could use the string to find the distance around the bust (or whatever you wanted to measure), mark the point at where the string starts to overlap, then measure the string using the ruler.
What is a convenient tool for measuring the circumference of a pipe?
A convenient tool for measuring the circumference of a pipe is a flexible measuring tape, which can easily wrap around the pipe's surface. Alternatively, a piece of string can be wrapped around the pipe, and then the length of the string can be measured with a ruler. For more precise measurements, a caliper can also be used to measure the diameter, which can then be used to calculate the circumference using the formula (C = \pi \times d).
What happens if you lower the frequency of a wave on a string?
Lowering the frequency of a wave on a string will result in a longer wavelength and a lower pitch sound.

What is the circumference of a cup?
A cup is usually a roughly cylindrical hollow container. The circumference of a cup would be the length of a piece of string wrapped around the cylinder.
A cylinder 72 cm high has a circumference of 24 cm A string makes exactly 4 complete turns round the cylinder while its two ends touch the cylinder's top and bottom How long is the string in cm?
If you open the cylinder it becomes a rectangle. Because the string encircles the cylinder four times while it moves up the cylinder's height, it then moves around 24cm x 4 = 96cm of "horizontal" (level with the base of the cylinder or the rectangle that is formed) distance and 72cm of the "vertical" (up the cylinder) distance. These distances form a right-angled triangle. By using Pythagoras' theorem, a2 + b2 = h2, where 'h' is the hypotenuse of the triangle and the length of the string, we can calculate the actual length of the string as thus: h2 = a2 + b2 = 722 + 962 = 5184 + 9216 = 14400 h = the square root of 14400 = 120cm. ---- Another method uses the same idea, but forms four identical triangles; one for each turn of the string around the cylinder. When the cylinder is unrolled into a rectangle as before, each triangle has a horizontal distance of 24cm and a vertical distance of 72cm/4 = 18cm. Using Pythagoras' theorem again, we can calculate the length of the hypotenuse of one of these triangles, which works out as 30cm. We have four such triangles, so multiplying that by 4 gives an answer of 120cm, just as before.

To determine the tension in a string, you can use the formula T F L, where T is the tension, F is the force applied to the string, and L is the length of the string. By measuring the force and length, you can calculate the tension in the string.
