2952.	Why water is not used to control the fires involving olis
Answer» Water cannot put off fire produced due to burning PETROL and oil because water is HEAVIER than oil. It settles down or sinks below the oil PARTICLES and cannot BRING the ignition temperature of the substance down or cannot cut off the supply of air to the fire. HENCE, oil keeps on burning on the top.

Find the thrust required to exert a pressure of 50,000 pascal on an area of 0.05m2

Answer»

Question-

Find the thrust REQUIRED to EXERT a PRESSURE of 50000 Pascal on area of 0.05m².

Given-

Pressure = 50000 Pa

Area = 0.05m²

To find-

Thrust or force

Calculation-

We know,

${\underline {\boxed {\rm {\blue { P = \frac { Thrust}{Area} }}}}}$

So,

${\boxed {\sf {\red { Thrust = Pressure \times Area } }}}$

Substituting values-

$\sf { ☞ Thrust = 50000N/m² × 0.05m²}$

$\sf { ☞ Thrust = 500\cancel 0\cancel0 \times \frac{5}{1 \cancel 0\cancel0} }$

$\sf\red { ☞ Thrust = <klux>2500N</klux> }$

The thrust required to exert a pressure of 50000 Pascal on area of 0.05m² is 2500N.

Answer» <U>Given:- ▪︎Mass(m)=200g =>200/1000 =>0.2kg ▪︎Initial VELOCITY(u)=5m/s ▪︎Final velocity(v)=17m/s To find:- ▪︎CHANGE in linear MOMENTUM of the body. Solution:- We know that change in linear momentum of a body is --- =>Final momentum-Initial momentum =>mv-mu =>m(v-u) =>0.2(17-5) =>0.2×12 =>2.4kg m/s Thus,change in linear momentum of the body is 2.4 kgm/s

2976.

A body of mass 200g is moving with a velocity of 5m/s. If the velocity of the body changes to 17m/s , calculate the change in linear momentum of the body.

Answer»

<U>Given:-

▪︎Mass(m)=200g

=>200/1000

=>0.2kg

▪︎Initial VELOCITY(u)=5m/s

▪︎Final velocity(v)=17m/s

To find:-

▪︎CHANGE in linear MOMENTUM of the body.

Solution:-

We know that change in linear momentum of a body is ---

=>Final momentum-Initial momentum

=>mv-mu

=>m(v-u)

=>0.2(17-5)

=>0.2×12

=>2.4kg m/s

Thus,change in linear momentum of the body is 2.4 kgm/s

3000.	A normal force of 100 N can produce a pressure of 10000 Pa. Calculate the area in cm2 on which the force shall act to exert the pressure.
Answer» GIVEN :- Force = 100 N PRESSURE = 10000Pa To find :- Area in cm² Solution :- As we know that ➭ Pressure = Force/Area ➭ 10000 = 100/Area ➭ Area = 100/10000 ➭ Area = 1/100 = 0.01m² ☞ 1m² = 10000cm³ Hence, Area = 0.01 × 10000 = 100cm² Extra Information Force = MASS × acceleration S.I unit of Force is Newton (N) 1m = 100cm S.I unit of pressure is PASCAL (P)

3000.

A normal force of 100 N can produce a pressure of 10000 Pa. Calculate the area in cm2 on which the force shall act to exert the pressure.

Answer»

GIVEN :-

Force = 100 N
PRESSURE = 10000Pa

To find :-

Area in cm²

Solution :-

As we know that

➭ Pressure = Force/Area

➭ 10000 = 100/Area

➭ Area = 100/10000

➭ Area = 1/100 = 0.01m²

☞ 1m² = 10000cm³

Hence,

Area = 0.01 × 10000 = 100cm²

Extra Information

Force = MASS × acceleration
S.I unit of Force is Newton (N)
1m = 100cm
S.I unit of pressure is PASCAL (P)
