As we KNOW, LIQUID pressure is more in the depth than the top. Therefore,walls of dams are made thicker in the BOTTOM to TOLERATE the pressure of water in the depth

GIVEN:

The ratio of ONE micron to one fermi

To find:

The ratio of one micron to one fermi is?

Solution:

One micron is equal to ten to the power -6

One fermi is equal to ten to the power -15

So, the ratio is given by,

Ratio = micron / fermi

= 10^{-6} / 10^{-15}

= 10^{-6+15}

= 10^9

∴ 10^{-6} / 10^{-15} = 10^9

Ten to the power 9 is equal to 1 giga

∴ micron / fermi = giga

Limitation of Ohm's Law. The limitations of Ohm's law are EXPLAINED as follows: This law cannot be applied to UNILATERAL networks. A unilateral network has unilateral elements like diode, transistors, etc., which do not have same VOLTAGE CURRENT relation for both DIRECTIONS of current.

HI FRIEND... HERE IS THE ANSWER...

It  is the speed at which the sum of an OBJECT's kinetic energy and its gravitational potential energy is equal to ZERO. It is the speed needed to "break FREE" from the gravitational attraction of a massive body..

the escape velocity on Mars is 5km/sec....

I HOPE I HELPED YOU..

PLEASE MARK IT AS BRAINLIST IF IT'S HELPFUL...

QUANTAM MECHANICS is not the BRANCH

Inertia is a property of a body which RESISTS or continues in the same state of motion or rest UNLESS an external force ACTS on it ...

EG a car won't stop until we apply BRAKES

ANSWER:
The VELOCITY of the PARTICLE after TIME t is GIVEN by :- v=u+at.

what is the QUESTION

A = dv/dt = -2T so AVERAGE a = -2×3+ -2×4 + -2×5 / 3= -8 so the PARTICLE deaccelerated by 8m/s^2

Pressure is DEFINED as force per unit area. It is USUALLY more convenient to use pressure rather than force to describe the influences UPON fluid BEHAVIOR. The standard unit for pressure is the PASCAL, which is a Newton per square meter.

Because the weight of PERSON is distributed over all MAIL which LEADS to less pressure on nails but the f you t lie on only one nail than the weight are not distributed and cause SEVERE injury
(hope it's helpful to you)

Because Its sound is of high frequency just LIKE the sound of CRYING babies.

hope this HELPS......

WHAT IS THE QUESTION HERE??????

I DONT UNDERSTAND THIS!!!!! !!!!!!!

The AVERAGE SPEED is 60+30/2=45

Hey DEAR frnd...
examples are given below:-
1- Skin have a large area to reduce the pressure on the SNOW. it ENSURE that the SKID don't sink in to the snow too far...
2:- Area of the edge of the knife blade is extremely small so this create pressure high enough for the blade to cut through any MATERIAL.....
hope it's help u dear

Here we will use Second Equation of MOTION i.e. s=ut+1/2at^2

120=0*8 + 1/2*a*8^2

120 = 1/2*a*64

120 = 32*a

120/32 =a

3.75 =a

3.75 m/s/s or METER PER second per second

Sorry I have not YET STUDIED MAGNETIC EFFECTS of electric CURRENT

No work is not done because according to physics if the body on which force is APPLIED is getting displacement then it is CALLED work.in this case the wall will OBVIOUSLY not move from its original place so work done is zero.

Due to hot NESS the MERCURY RISES and it CATCHES heat EASILY

s=150 m t=8 sec

u=0

s=ut+1/2 at^t

150=0+1/2 a^8^8

150=32 a

32a =150

a =150/32

a=4.68

Because the MASS of the HEAD is more than that of water whereas mass of body BECOMES lesser than that of water

Because from adernalin the enzymes were released and we cannot control our EMOTION and THING which was happened were FIXED it into our mind it makes UN happy

In the SPECULAR OBJECT case, it bounces BACK most of the light. But the diffused one will bounce not MUCH light...

e=it=0.2x0.5=0.1coulamb

e=it=300MAx60=1.8x10^8c

The SPEED of sound increases with INCREASING density.

The FLOOR will exert a normal FORCE EQUAL to the MG force i.e. 250N.

The escape velocity is the minimum velocity required to LEAVE planet or MOON. For a rocket or other object to leave a planet, it MUST overcome the pull of gravity. The FORMULA of escape velocity contains a constant G, which is called universal gravitational constant.
Please mark me a BRAIN list.

The main concept involved here is that of Total Internal Reflection (TIR).



As LIGHT moves from an optically denser medium to an optically rarer medium, it moves away from the normal.

So, as the angle of incidence increases, the angle of refraction also increases.

For a specific angle of incidence (called the Critical Angle), the angle of Refraction becomes 90°

At ANGLES of incidence above this critical angle, light gets reflected back into the denser medium.



Here, in the question, a glass slab is placed on a point light source.

A light source emits light in all directions.


So there are light rays coming to the other surface of the slab at every angle.


However, we just saw that if the angle of incidence at the other surface is GREATER than the critical angle, light won't come out from the surface.

This implies that all light doesn't escape.


The light, whose angle of incidence is less than critical angle can only escape.

Thus, the light comes out only from a circular region on the other surface of the slab.


The boundary of this CIRCLE defines the critical angle of incidence.


The solution is shown in the image.

Final Answer:

Radius of Circle is 6 cm.

HI FRIEND....

Data AVAILABLE in an unorganised form are CALLED raw data. The number of times a particular observation occurs in a GIVEN data is called its frequency.....

The rate constant goes on increasing as the TEMPERATURE goes up, but therate of increase falls off quite rapidly at higher TEMPERATURES. A catalyst willprovide a route for the reaction with a LOWER activation energy. ... And the rate constant k is just one FACTOR in the rate equation.
