Answer 1

Question 1

Pressure = Force/ Area

               = 100/2 = 50N/m^-1

Option C

Question 2

Deep sea divers will have an atmospheric diving suit which block the heavy pressure of the water around them, and keep a decent pressure inside.

Question 3

A. depth, acceleration due to gravity and density

       Because Pressure = densityxgh

B. Pascal's law for fluids

C. rate of momentum and direction changes

Hope it helps

Answer 2

$\huge\mathfrak{QUESTION-1}$

A force of 100 N is applied to an object if area 2 m² . The pressure exerted is equal to:

A)20 Nm²

B)50 Nm²

C)50N/m²

D)50Nm²

EXPLANATION(1):-

Using the formulae= $\bold{pressure}=\bold{\frac{force}{area}}$

Force=100 N

Area=2 m²

$\bold{pressure}=\bold{\frac{50}{2}}$

$\bold{pressure}=\bold{50\:Nm^2}$

So opt-[B] is required answer.

$\huge\mathfrak{QUESTION-2}$

Why do deep sea divers wear specially designed suits?

EXPLANATION(2):-

The suit which they wore helps in blocking the heavy pressure of water ,which is present around them upright pressure inside.

$\huge\mathfrak{QUESTION-3}$

a)The pressure exerted by liquids depend on _____,_______ & _______.

b)Pressure applied to a liquid is transmitted equally in all directions. This statement is known as ______.

c) Force acting on a body can change it's ________ and _______.

EXPLANATION(3):-

a)The pressure exerted by liquids depend on depth,acceleration due to gravity &density of the body

.b)Pressure applied to a liquid is transmitted equally in all directions. This statement is known as pascal's law of fluid.

c) Force acting on a body can change it's shape and size.
