What is Pressure ? Explain well
Andreyy89







Hi Pupil Here's Your Answer ::





➡➡➡➡➡➡➡➡➡➡➡➡➡





Pressure is defined as the force acting perpendicular on an unit area of the surface.


OR


The thrust per unit area is called Pressure.

let us see, on what factors the pressure depends?


Take a pin having a pointed end and a nail having blunt end. Press then against a cardboard by applying the same force. We find that the pin penetrates deep into the cardboard then the nail. In this case, force acting on two points of the cardboard is same but the area under the tip of the Pin is less than under the tip of the nail.

The effect of the forces of the scene magnitudes on the different area is different.


Conclusions : Pressure acting on the surface is inversely proportional to the area of the surface on which force acts.

A 70kg car drives through a curve with radius 50m. What is the minimum angle the road should be tilted to keep the car on the ro
worty [1.4K]

when car moves along a circular path then centripetal force for taking turn will be provided by the component of normal force

Let the road is tilted by some angle

so force equations are given as

F_n cos\theta = mg

F_n sin\theta = \frac{mv^2}{R}

now divide two equations

tan\theta = \frac{v^2}{Rg}

now as it is given to us that

v = 80 km/h

v = 80* \frac{5}{18} = 22.2 m/s

R = 50 m

now we have

tan\theta = \frac{22.2^2}{50*9.8}

tan\theta = 1

\theta = tan^{-1}1

\theta = 45^0

so it is inclined at an angle of 45 degree

Give v=120m/s north and t = 10.2, calculate the displacement
Sedbober [7]

Answer:

Displacement from the starting position is 1224m

Explanation:

The object is moving at 120 meters per second, it does this for 10.2 seconds. Use multiplication to find the answer.

120 \times 10.2 = 1224
