Make a pinhole camera by putting a pinhole in your piece of cardboard. Hold a piece of paper one meter away from the cardboard. Your pin-hole camera will cast an image of the sun on your paper. Measure the diameter of the image cast on your paper. The ratio of the sun's actual diameter to its distance from the earth is the same as the ratio of the diameter of the sun's image to the distance between the cardboard and the image. In other words, the diameter of the sun (X) divided by the distance from the earth to the sun is equal to the diameter of your image divided by the distance from the pinhole to the image. Good luck.

It depends on what you mean by measure, but if you mean in regard to the "50 caliber" part, caliber is the diameter of the piece of lead.

Measuring the inertia of a penny can be done by equation or experiment. The experiment is as simple as placing the penny on a piece of cardboard on top of a cup. Flick the cardboard, which will move, and the penny just falls into the cup.

Mixed meter is when one piece of music has multiple meters or time signatures during the piece. A simple example: A song's verse is in 4/4, but the chorus is in 3/4 time. However, mixed meter more commonly means that the meter changes frequently (often every measure) during a piece. In these cases, the lower number in the time signature usually remains constant. For example, the meter might change every measure from 3/8 to 6/8 to 5/8 to 9/8 to 12/8, etc.

'Square meter' is a unit used to measure area or coverage, such as the floor of a room, or a piece of land. 'Cubic meter' is a unit used to measure volume or capacity, such as a bottle, or a barrel. These two units have different "dimensions", and are used to measure different types of quantities. Neither one can be converted into the other one.

A capacitance meter is a piece of electronic test equipment used to measure capacitors. Depending on the sophistication of the meter, it may simply display the capacitance or it may also measure a number of other parameters such as leakage, equivalent series resistance, and inductance.

First draw a circle using a compass. Now, use a piece of string to help measure the circumference of the circle. Now measure the diameter of the circle. To discover Pi divide the circumference by the diameter.

To calculate the price per square meter, divide the total price by the total number of square meters. For example, if a piece of cardboard with an area of 10 square meters cost 5 dollars, the price per square meter would be (10 m2)/($5), which comes out to be 50 cents per square meter.

Not sure what your level is; this may not be appropriate. You can make a pin-hole projector and actually project an image of the sun onto a piece of cardboard. If you do it right, you can get an image that is large enough so that sunspots may even be visible! You could also have classmates do an actual estimate of the diameter of the sun (or you could explain how you did it with your projector). If you carefully measure the distance between the pinhole and the surface you project the sun's image onto, and then carefully measure the diameter of the image right at that distance, you can do something interesting. The proportion of the 2 lengths is the same, no matter how big the distance gets. Can you see how you would "measure" the diameter of the sun this way? By the way, never, never, never look directly into the sun.

Its weight varies depending on how much corrugated cardboard you have. If you have a small piece, it will not weigh very much. If you have a pallet of corrugated cardboard, it will weigh a whole lot.

Meter is to measure a length. Square meter is to measure an area. If some terrain has a rectangular shape you can calculate it's area simply multiplying length by width, and you get total area in square meters. For instance, if a piece of land is 10m long and 4m wide, it's area is 40 sq m (40 multiplied by 4 equals 40).
