1.

How much force should be applied on an area of 1 cm² to get a pressure of 12 Pascal?

Answer»

ʜᴇʟʟᴏ ᴍᴀᴛᴇ!

PRESSURE = FORCE / Area

Pressure = 12 Pa

Area = 1 cm², now convert in into m²
= 0.0001 m²

12 Pa = F / 0.0001 m²

12 × 0.0001 or 0.0012N = F

Answer: Force = 12 × 10^-4 N

Hope it HELPS

3.

a man walks at the speed of 6km/hr for 1 hour and 8km/hr for the next 1km.what is his average speed for the walk of 2km

Answer»

Hii..
Here is your answer..

Solution:-
First he walk at speed of 6km/h
Speed=6km/h
Distance = 1 KM

So,
time =  \frac{distance}{speed}  \\  =  >  \frac{1}{6} h
Then,
He walk at speed of 8km/h
Speed=8km/h
Distance=1km
Time =D/S
=  >  \frac{1}{8} h
Now,
We KNOW that,
<klux>AVERAGE</klux> \: speed =  \frac{total \: distance}{total \: time \: taken}  \\  =  >  \frac{1 + 1}{ \frac{1}{6} +  \frac{1}{8}  }
=  >  \frac{2}{ \frac{4 + 3}{24} }
=  >  \frac{2 \times 24}{7}  \\  =  >  \frac{48}{7}  \\  =  > 6.85
Hence,
Average speed=6.85km/h

Hope it helps uh...✌️✌️✌️

==>>Your question was QUITE WRONG it should be " a man walks at speed of 6km/h for 1 km__________.

the potential energy of a particle of mass 1 kg moving along x axis is given by U(x) = (x^2/2 - x) J if the total mechanical energy of particle is 2 J then find its maximum speed

Answer»

2Speed will be max when kinetic energy is MAXIMUM so potential energy will be MINIMUM so differentiating the function put it equal to 0 so we obtain minimum for x=0 now kin potential energy is 0 and kinetic energy will be 2 .mv^2/2 is equal to 2 m is 1 kg therefore v=2 .

Explain the directory rules France

Answer»

French Directory. The Directory or DIRECTORATE was a five-member committee which governed France from 1795, when it replaced the Committee of Public Safety. On 9 November 1799, it was overthrown by Napoleon Bonaparte in the Coup of 18 Brumaire and replaced by the French Consulate.The wealthier middle classes seized POWER and formed a new constitution. It provided for two elected legislative councils. These then appointed a Directory, an executive made up of five MEMBERS. This was meant as a safeguard against the concentration of power in a ONE MAN executive as under the Jacobins.Directory is the name for the five member committee appointed by king.  This was during a few years before the revolution.
The five directors ruled the country. they overthrew the public safety committee..  It was from 1795 to 1799

Why can't we sneeze with our eyes open

Answer»

The nose and eyes are LINKED by cranial nerves, so the stimulation fromthe sneeze travels up one nerve to thebrain, then down another nerve to theeyelids, triggering a BLINK for most people. HOWEVER, it's possible for some people to sneeze with their eyes open — without fear of PEEPER LOSS.

The speed of a rocket is 12 km second and the speed of a snail is 12 cm second .compare their speed

Answer»

12km/second is SPEED of ROCKET
1km=1000m
12km=12000m
1m=100cm
12000m =120cm
12cm / second is the speed of snail 120cm is GREATER than 12cm
speed of rocket is greater

It will not be ASKED in exams....You should not LEARN it but... you should have the UNDERSTANDING of it.... so
a\c to the sign of convention.... Anything right is positive and anything left is negative and anythong up is positi e and anything down is negative.... or in your book it is GIVEN that... Sign is taken as + (positive) behind the spherical mirror.
The height of is taken as + (positive) above the PRINCIPAL axis and taken as – (negative) below the principal axis.
The DISTANCE is taken negative when measured in frony of the mirror....
just r3m3mber that RIGHT POSITIVE UP POSITIVE LEFT NEGATIVE AND DOWN NEGATIVE.

To determine the motion of centre of mass which Newton's law is used?

Answer»

Newton's second law of MOTION pertains to the behavior of objects for which all existing forces are not balanced. The second law STATES that the acceleration of an object is dependent UPON two variables - the net force ACTING upon the object and the MASS of the object.

What is a friction and with suitable example

Answer» FRICTION is the FORCE resisting the relative MOTION of solid surfaces, FLUID LAYERS, and material elements sliding against each other.
friction helps in writing walking etc
27.

What is a fiction and with suitable example

Answer» FRICTION is the opposing force ACTING on a body is called friction.As an object FALLS, air resistance pushes up on the object. When you ride a bicycle, the contact between the WHEEL and the road is an example of rolling friction. When an object rolls over a SURFACE, the force needed to overcome rolling friction is much less than that needed to overcome sliding friction.

How do you prove experiment that action and reaction forces are acting two different objects

Answer»

Example : if we throw a ball by force to the wall ,so the ball also gives us the smart force this is our REACTION!!!
example: if we kick a foot ball by force, so the for ball also gives us the same force this is our reaction!!
example: if we slap a person, or have will also pain and that person's cheek will also pain this is our reaction!!!
to EVERY action there is EQUAL reaction!!
this is Newton's third law of MOTION ...

Why lorries have chain in the bottom

Answer»

As the lorries have all the weight at the BOTTOM, the center of mass would be at the bottom RATHER than on the TOP. So if the chains are at the top, the chances are that the weight will PULL it down and the LORRY will be pulled down by the side and it will flip over.

???? plz answers this question guys....

Answer»
formula \: to \: be \: used \:
p =  \sqrt{ {a}^{2} +  {b}^{2} + 2ab \cos( \alpha ) }
this \: is \: used \: for \: finding \: magnitude \:
of \: two \: vectors \: having \: angle \: of \:  \alpha
between \: them
using \: this \: formula
we \: have \: to \: find \: magnitude \: of \: 60 \:
and \: 30.

p =  \sqrt{ {30}^{2}  +  {60}^{2} + 2(30)(60 \cos(60) }
so \: p \:  =  \sqrt{3600 + 900 + 2(30)(60)0.5}
hence \: p =  \sqrt{6300} = 30 \sqrt{7}
as \: there \: are \: i n \: equilbrium \: p \: has \:
magnitude \: of \: 30 \sqrt{7}

hence \: 30 \sqrt{7}  \: is \: the \: answer \:
(d) \: is \: the \: correct \: option.
