Measuring Tools

a thermometer thermometer a thermometer

A caliper to measure BMI ( Body Mass Index.) -or in other words, how fat you are.

well the tool would use a triple beam balance because it has more mass.

It is designed to measure the temperature of the human body and so does not require a long range.

Well the best way would be to implant a chip in all students (like you do with pets) and put a chip reader in all the school doors, this would record when every student entered and left a room.

The vernier caliper is more accurate that a plastic ruler. That's because the caliper is designed to be used and effectively read to measure small distances. And it does this better than a "regular" ruler because it has a vernier scale built into it. It's like an "amplified ruler" attached to the device that has increased accuracy. A link is provided to the Wikipedia article on the vernier caliper and to the one on the vernier scale. Check out the pictures and skim the details. You should be able to pick it up with a bit of thought.

If the force gauge isn't moving, the the net force must needs be zero.

Litmus does not change color in sugar solution.

Because they were invented by Pierre Vernier in 1631.

Not a good idea to connect Copper to Steel (Hopefully Galvanized (sp)) Many products are available. Check out any hardware store or home improvement center. (New Commentator) Rarely is Teflon tape a good idea. A fragment can and will break off, affecting something down the line.(valves,gauges,etc.) "Dope" is usually a better solution.(we are speaking of pipe dope here) What the earlier commentator what trying to get you to understand, is that when two metals meet, a battery is created. Steel and copper will interact with each other even on a low temperature(lower energy)line. Both materials will be affected,corroded, and your line will eventually clog,as it rots. Uniform materials might seem less expensive in the short term, but, in the long term, which depending on a number of variables, may only a few years, can cause a complete do over. (Very expensive) Prior commentator was hoping at least, you meant galvanized steel, because, the death of your pipes will be delayed a bit. If you can,change the female to copper. Just make sure the wall is thick enough. Try to use 'western' plumbing materials. There is a reason they cost more, and most of that reason is more uniform standards, better casts, threads that actually make a secure join, and try to stay away from the plastics. If you do the job right, you shouldn't have to do it again.

a syring is the tool for mesuring mass.

Several things might be wrong; it may be that the scale is broken, that the battery isn't working, or that there is a bad contact with the battery. You might try with another battery, if you suspect the battery.

2.25 centimeters are equal to 22,500 micrometers.

Some of the tools that a registered nurse uses include a stethoscope, a blood pressure cuff, and syringes. A registered nurse will also use a computer, an autoclave, and even bandages and scalpels in some cases.

you measure the computer screen diagonally, so if you have a 17" computer screen, and you measure it straight from side to side, then its not 17". You have to measure diagonally. I.e. Top left coner of the screen ( do not include the housing) to the bottom right side of the screen

The triple beam balance is used to weigh an object's mass in grams.

A device used in manufacturing and engineering, to determine whether a dimension is larger or smaller than a reference standard.

A snap gauge, for example, is formed like the letter C, with outer "go" and inner "not go" jaws, and is used to check diameters, lengths, and thicknesses. Screw-thread pitch gauges have triangular serrations spaced to correspond with various pitches, or numbers of threads per inch or per centimeter.

You would use a dry matter cup.. Usually plastic or metal, l know that they have 1 Cup container, they might have 1/3 cup, 1/2 cup and everything like that too but l'm not sure, l hope l helped you a little bit. :)

Purchase the appropriate sized easy out and drill bit from an auto parts store and drill into the center of the bolt head, you then insert the easy out and its reverse threads will back the bolt out. ( as you tighten the easy out counterclockwise the bolt will loosen )

One of the first reasons early people needed to measure time was to know when to plant and harvest their crops.

It isn't.

Navigation by the stars is far more accurate than navigation with a compass, as magnetic north is different at different locations while north determined by the stars is the same at all locations.

A frequency counter is the most accurate way. As stated above some digital multimeters include this feature, but stand alone frequency counters are also available.

Another way is to use an oscilloscope and measure the period of one cycle, then calculate the frequency as the reciprocal of the period you measured.

Another way is to use a multiple tuning fork frequency meter. These devices have perhaps a dozen tuning forks tuned to different frequencies (with the 60 Hz fork in the center, lower frequency forks to the left, and higher frequency forks to the right) and an electromagnetic excitation coil. The tuning fork(s) closest in frequency to the powerline will vibrate and the others will remain stationary, allowing you to read the frequency. They are a bit course in their measurement, but usually can identify differences of about 0.1 Hz.

However, if your home is powered from the national power grid (not a local generator) the frequency is required to be 60 Hz to a precision that a clock synchronized to the power line will never be more then 10 seconds fast or slow of the correct time, although the line frequency might be high or low for short periods as much as a couple Hz.

If it is a 2x2x2 and a 12x12x12 house then you find the volumes and divide

12x12x12/(2x2x2)=216

Else it is this, by using area

12x12/(2x2)=36
