Which of the following is the CGS unit of energy?

Which of the following statements is/are incorrect?

The volume of an irregular shaped solid can be measured by using a _____.

Which of the following statements is incorrect?

An atlas of a country is shown in the figure, the distance between cities A and B is _____.

Find the correct arrangement of the following steps in sequence to find the volume of an irregular shaped solid body.

(A) The irregular shaped solid is tied with the thread and is lowered into the measuring scale.

(B) Take a measuring cylinder with graduations in millimeters

(C) The level of water in the measuring cylinder rises after immersion of solid(say $V_2$)

(D) First it is filled with water to a certain level or volume (say $V_1$)

(E) The volume of stone is equal tot the difference between the volume of the water after and before the immersion of the stone($V_2-V_1$).

Density of the material of a paper is given as $0.5 \mathrm{g}/{\mathrm{cm}}^3$. The mass of the paper is $1 \mathrm{g}$ and its length and breadth are $10 \mathrm{cm}$ and $5 \mathrm{cm}$ respectively. Arrange the given steps in a sequence to find the thickness of the paper.

(A) The thickness of the paper$=\frac{\mathrm{Volume}\left(V\right) \mathrm{of} \mathrm{the} \mathrm{paper} }{\mathrm{length}\times \mathrm{breadth}}$

(B) The density (d) of the material of the paper$=\frac{\mathrm{mass} \mathrm{of} \mathrm{the} \mathrm{paper}\left(m\right)}{\mathrm{volume}\left(\mathrm{V}\right)}$

(C) Then the volume (V) of the paper$=\frac{\mathrm{Mass} \mathrm{of} \mathrm{the} \mathrm{paper}\left(m\right)}{\mathrm{Density}\left(d\right) \mathrm{of} \mathrm{the} \mathrm{paper}}$

(D) The volume (V) of the paper $=\mathrm{length}\times \mathrm{breadth}\times \mathrm{thickness} \mathrm{of} \mathrm{the} \mathrm{paper}$

Which of the following is/are the unit(s) of pressure?
