The approximate length of an unsharpened no.2 pencil is

Option (b) is correct. The approximate length of the unsharpened pencil is almost   or .

Explanation:

The measurement of the quantity is the most fundamental requirement for the  estimation of any quantity. The measurement of length of a body is done using the standard unit of measurement which is meter.

The approximate length of an unsharpened pencil is considered to be almost .

In order to express the length of the pencil in the standard unit of measurement of length, we should know about the conversion factor.

One meter is considered to be equal to the of the length. The conversion factor can be expressed mathematically as:

The length of the pencil can be expressed in terms of standard unit as:

Thus, option (b) is correct. The approximate length of the unsharpened pencil is almost   or .

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
