Answer 1

Answer:

How will you show that the pressure exerted by a liquid on the base of the container depends on the height of its column?

TO SHOW THAT PRESSURE EXERTED BY LIQUID AT THE BOTTOM OF THE CONTAINER DEPENDS ON HEIGHT OF COLUMN.. PROCEDURE: Take a plastic bottle or a beaker which has tube like structure. ... You can observe that water flowing out from top holes are coming with less force and falling just infront of the beaker.Jun 1,

Answer 2

Given:

A particle travelled from A to B by following the path of AOB

Radius of circular path, r= 14 m

To Find:

Distance covered by particle and displacement of particle

Solution:

We know that,

• $\purple{\boxed{\bf{Circumference=2\pi r}}}$

where r is radius

• Distance is the length of actual path covered by body
• Displacement is the distance between starting and final position

$\rule{190}{1}$

Let the circumference of given circular path be 'C'

So,

$\longrightarrow\rm{C=2\pi r}$

$\longrightarrow\rm{C=2\times\dfrac{22}{7}\times14}$

$\longrightarrow\rm{C=\dfrac{616}{7}}$

$\longrightarrow\rm{C=88\:m}$

$\rule{190}{1}$

Let the distance covered by particle be D and displacement of athlete be d

From the figure, it is clear that

$\longrightarrow\rm{D=Length\:of\:AOB}$

$\longrightarrow\rm{D=\dfrac{C}{2}}$

$\longrightarrow\rm{D=\dfrac{88}{2}}$

$\longrightarrow\rm{D=44\:m}$

Now,

Since, B is situated at diametrically opposite location of A

So,

$\longrightarrow\rm{d=Length\:of\:AB}$

$\longrightarrow\rm{d=2r}$

$\longrightarrow\rm{d=2\times14}$

$\longrightarrow\rm{d=28m\:\hat{AB}}$

$\rm\hat{AB}$ because displacement of particle is toward B from A

Hence, distance covered by particle is 44 m and displacement of particle is 28m $\rm\hat{AB}$ .
