You can use a tool called a Caliper. It will measure small objects (less than 6 inches) very accurately. For larger objects you can carefully use a construction tape measure.
I find it stressful dealing with not knowing very accurately where the object that I'm measuring even is.
A ruler can be very helpful.
Yes, but not very accurately.
Unfortunately, not many. We can accurately measure its location and orbit, by watching the object for several months or years. We can make a good guess of its size, based on the brightness, since we know the distance pretty accurately. We can calculate the composition of the surface based on the spectrum of light that we see. A couple of things that are very difficult to determine from here are the mass and density of the object. We can calculate these very accurately if the asteroid has a satellite, or if we send a space probe there to orbit the object. We've done that only for a very few asteroids.
- The meter is a unit of length, the bar a unit of pressure.- If you think to the object bar the length is very variable
The image is formed behind the lens at a distance equal to the focal length. If the distance to the object is D1 and the focal length is F, then the distance D2 to the image is given by this equation: 1/D2 = 1/F - 1/D1
Very accurately.
Pick any number greater than 366. Then find an object whose measure it that length. Alternatively, cut to the chase and go for something very long straight away - like the road from your town to the next!
The "day" on any object in the solar system is very nearly the length of time the object takes to rotate on its axis ... or the length of time between as seen from its surface. The "asteroid belt" is a loosely contiguous group of millions of individual objects, and each one has its own "day".
This depends on the length of the object.You can use mm for very short objects, cm for short objects, m for long objects; and working with a microscope we use μm.
When you are rounding out to the nearest inch. * * * * * Very funny! If the length is between (x-0.25) inches and (x+0.25) inches it will be rounded to x inches.
First concentrate on reading accurately. Read a lot and read often, and soon you will be reading faster.
