Four pieces of wooden sticks P, Q, R and S are placed along the length of 15 cm long scale as shown in figure. What is the average length of these sticks?

0%
2.0 cm
0%
2.5 cm
0%
2.6 cm
0%
2.9 cm

Explanation

The length of the different sticks is as follows:

$P = 2.1 cm;\\ Q = 3.0 cm;\\ R = 3.1 cm;\\ S = 2.5 cm$

Average length of these sticks

$=\dfrac{P+Q+R+S}{4}$

$= 2.6 cm$

0%
parsec

Explanation

SI unit of length is Metre, denoted by (m).

Angstrom is a unit of length and 1 Angstrom = ${{10}^{-10}}m$

Fermi is a unit of length also known as femtometre and 1 fermi = ${{10}^{-15}}m$

parsec is a unit of and 1 parsec = $3.085\times {{10}^{16}}m$

barn is unit of nuclear cross section, not length

$\textbf{Answer}$

A length is measured as

$7.60\ m$ . This is the same as

0%
$760\ mm$
0%
$0.0076\ mm$
0%
$760\ cm$
0%
$0.76\ dm$

Explanation

Length

$l=7.6m$

we know

${ 1 \ m }=100 \ cm=1000 \ mm=10\ dm$

$\therefore l= 7.6 \ m=(7.60\times 100)cm=(7.60\times 1000)mm=(7.6\times 10)dm$

$\Rightarrow l= 7.6 \ m=760\ cm=7600\ mm=76\ dm$

So, the option C is the correct one.

An object is said to be in motion, if its position (with respect to another object)
