Given,

Pressure to be exerted → 10 Pascal

Area to experience the force → 10000 cm²

                                            → 10000 ÷ (100)² m²

                                            → 1 m²

To find: Force

We know Pressure = $\frac{Force}{Area}$

⇔ where the area is in m² , Force is perpendicular to the area in N and

Pressure obtained is in Pascal

Now,

Force = Pressure × Area

⇒ Force = 10 × 1

              = 10 N

Answer : 10 N

I hope it helps you and if you appreciate my answer, please respond with a thanks ☺.

Answer 2

Step-by-step explanation:

GIVEN :-

• Force , F = 10000 N.
• Time , t = 10 seconds.

TO FIND :-

The change in momentum of a car , ∆p.

SOLUTION :-

As we know that the rate of change in momentum of any object is given by,

$\\ : \implies \displaystyle \sf \: \Delta p = m(v - u).$

Now, by using the second law of motion we have,

$: \implies \displaystyle \sf \: F = \frac{m(v - u)}{t}$

$: \implies \displaystyle \sf \:10000 \: kg.ms ^{ - 2} = \frac{m(v - u)}{10}$

$: \implies \displaystyle \sf \:10000 \: kg.ms ^{ - 2} \times 10s =m(v - u)$

$: \implies \displaystyle \sf \:100000 \: kg.ms ^{ - 2 + 1} =m(v - u)$

$: \implies \displaystyle \sf \:100000 \: kg.ms ^{ - 1} =m(v - u)$

$: \implies \displaystyle \sf \:100000 \: kg.ms ^{ - 1} =\Delta p$

$: \implies \underline{ \boxed{\displaystyle \sf \: change \: in \: momentum = 100000 \: kg.ms ^{ - 1}}}$
