Latent HEAT of Vaporization : It is the amount of heat absorbed or released to change a substance from liquid to vapour/gas or from vapour/gas to liquid without any change in temperature.
The value of vaporization of WATER is 2260*10^ 3 J/kg.

Hey Guys,

CRITICAL VELOCITY :-It is a velocity ( speed and DIRECTION ) at which the FLOW of liquid through a TUBE changes from LAMINAR (Smooth ) to turbulent .


Thanks.

When a person has FEVER, his BODY temperature becomes more than the normal body temperature. If we put strips of WET cloth on the forehead of a person suffering from high fever, the water evaporates taking heat from the body. Thus, moist strips will lower his body temperature.

An object FALLS FREELY to the ground has acceleration that is uniform as long as air resistance can be IGNORED and the object stays near ENOUGH to the earth's surface so that the GRAVITATIONAL field is constant.

The speed of Cars APPROACHING each other is add up because they approach towards each other with their own speed so it APPEAR to move FASTER with RESPECT to STANDING observer.

ANSWER:

answer for you by sherin KEEP you posted

Explanation:

i HOPE you.

KSF are specific to industry, sector of an industry, and geography. As such, scope of our STUDY is about identifying KSF of the UPSTREAM sector of oil and gas industry, DUE to global attentions to LIMITED natural resources and importance of efficiency in the oil and gasvalue chain.

The wave profile of a STANDING waves have ZERO VELOCITY hence it does not matter whether MEDIUM is at rest or in relative motion to effect the frequency of the standing wave

ANSWER:

Explanation:

Capacitance of SPHERICAL CONDUCTOR is 4πR*epsilon=4*3.14*8.85*10^-12, CALCULATE this you will get the answer

Hey friend!!
Here's your answer..
No, As absolute REFRACTIVE index is RATIO of speed of light in vacuum to that in the given mater, we can SAY it is always greater than one. ... Thus , absolute refractive index can NEVER be less than one .
Hope it helps you!!
Have a great day AHEAD!!:)

Magnitude , MAY be , here is momentum .
The answer is no , BODY can't acceleration , without change in Momentum .

; Momentum = Mass × Velocity .

; Acceleration is the change in Velocity of RESPECT with Time .

If Velocity changes , then , Momentum or Magnitude is also changes .



But , if the Magnitude , here , is FORCE , then .
Yes , Change in Magnitude = Change in Acceleration .

For CURRENT to be ZERO, the RESISTANCE MUST be infinite.
we have V=IR.
so I=V/R.
=>0=V/R.
or R=infinite.

any problem ask in COMMENT

Hey your ANS is here

______

given

a=2

u=0(as he starts from rest)

t=10

v=?

we know
a=v-u/t
2=v-0/10
20m/sec=final velocity

now to take out distance

we know

v2=u2+2as
(20)2=(0)2+2×2×s
400=4s
s=100m=distance

______

q=it ,

i=q/t

i=600/600=1A

HEYA!!
---------

----------------------------------------------------------------------------------------------------

GIVEN that ,

Initial velocity u = 0 { he starts from rest }

Acceleration a = 2m /s2

Time t =10 SECONDS

Final velocity v =?

Using first equAtion of MOTION,

V = U+ AT

V = 0 + 10× 2

V = 20 m/s.

Distance travelled s : ?

Using second equation of motion

S = UT + 1/2 at^2

= 0 + 1/2×2×100

= 100 m

----------------------------------------------------------------------------------------------------
----------------------------------------------------------------------------------------------------

Here..is.your..ANSWER..

By MUSCULAR FORCE it MAY be possilble.

U=0m/s
A=2m/s²
T=10s
Since,
V=u+at
:. PUTTING value
V=0+2×10
V=20m/s
Now,
V²=u²+2as
20²=2(2)s
400=4s
400/4=s
m=s

This is the ANSWER. L HOPE it will HELP you.

We know that,

R = (rho)*length/Cross SECTIONAL Area

Since, the length of the wire has doubled, hence there will DEFINITELY be some change in cross sectional area.

Now we know that, volume = Mass/Densityand since NEITHER mass nor DENSITY has changed due to change in length, thus volume must remain constant.

We further know that,

Volume = Length * Cross Sectional Area

This implies that, due to doubling the length of wire, the cross sectional area will BECOME half for volume to remain constant.

Thus we get, new cross sectional area = (1/2) of old cross sectional area

New length = 2 * old length of wire.

Putting these value into t

As the particle is MOVING with a CONSTANT speed V, following the Law of UNIFORM Circular Motion the speed when the particle completes one fourth of revolution will be constant.

(300+200)÷(3+5)

or,500÷8=62.5 SEC

Place a unit positive charge in between the charges
9 e and 3 e such that it is at a distance of x from the 3 e charge and (R-x) distance from the 9 e charge. As electric intensity is ZERO at the position of unit positive charge so K(1)(9e)/(r-x)^2= K(1)(3e)/(x^2). 3x^2=(r-x)^2. so (r-x)=√3x. r/(1+√3) =x.

Pressure=Force/Area.
so p=8/2=4.

⇒22400 ml CO2 obtained by = 168 g of NaHCO3

⇒300 ml CO2 obtained by = 168 x 300 /22400

=2.25 g

⇒Percentage purity = 2.25 x 100 /2.5

Air PRESSURE or Atmospheric Pressure is the pressure exerted by air on the surface of Earth ( Atmospheric Pressure also EXIST on other planets ) . The pressure of air is INCREASES with depth from Space .

The devices LIKE Barometer and Sphymomanometer etc works on principles of air pressure .

Barometer calculates the force of air on its one specific side and on this value , it calculates the pressure .

Sphymomanometer works on the features of fluid pressure . The pressure on one balloon like STRUCTURE , calculates the reading of Blood Pressure etc .

We should ARRANGE them in PARALLEL ARRANGEMENTS so they can work even after ONE BULB isn't working.
