You can find out the weight of an unknown object by using standard masses and a scale.
using the light alone to measure the weight of a unknown object is impossible.
YOU cant do it!! :)
A ruler. Using a ruler, you could measure the dimensions of the block which you could then use to calculate its area.
An easy way to do that is to weigh the object. In principle, the mass can be derived from the weight.
You could align the edge of the object with the zero on the ruler and then read off the marking on the ruler which aligned with the other end of the object.
You measure it, using a ruler of another measuring device.
Wrap the strip of paper around the plate or can and mark it where it completes a full circle around the object. Then lay the strip on a flat surface and measure the marked length using the ruler. That length is the perimeter (circumference) of the round object.
You cannot measure an angle using a ruler.
using a thermometer u can measure accurately at 1 decimal place
A scale, a stopwatch and a ruler. Weigh the object of which you want to know the momentum, and determine its speed using the stopwatch and ruler. The momentum can then be calculated as the product of the weight and the speed.
The ruler measured the length of the table to be four feet.
get a ruler,measure it and write it on a piece of paper.
A ruler is used to measure length and does not account for the height or width of an object, which are necessary to calculate its volume. To find the volume of a paperclip, you need to measure its dimensions in three dimensions using a tool such as a caliper or by using a water displacement method.
by using a ruler
You measure them, using a ruler or tape measure or similar.
Using a ruler which marked by Centimeters will more helpful to measure the distance of a map.
