Maximum no of ELECTRON in PRINCIPLE SHELL is given by the formula 2n^2
therefore maximum no. of electrons in L shell or 2ND shell is = 2×2^2
=2×4= 8 electrons

Answer:

EXPLANATION:

Resistance=

specific resistance*length/AREA

if wire is stretched n times, length is NL,area is A/n,

so new resistance increases to n square times

Their MASSES are expressed in solar MASS where 1 solar mass= 2×10^30 KG

Mass number is number of PROTONS and neutrons that cannot be fractional.
ATOMIC mass is ALSO equals to no. of protons +neutrons but it can be fractional because most of the elements occur as a mixture of ISOTOPES of different MASSES.
fractional atomic masses arise due to mass= total mass of all atoms /no. of atoms

A=u,INITIAL VELOCITY B=a,acceleration

A-b=(3i+2J+0k) - (I -2j +3K).
=2I +4J -3k.

This is a very extreme level of fanatical and hypothetical question..so I'll try my BEST to keep up the spirit of fantasy.

At first, I'd never take this fact seriously and think of it as a prank.

But if by any chance, if it were to be true, to be honest, I'd be very SCARED and might even lose my MIND but obviously it wouldn't be a good IDEA to go on telling people that the Earth's ending as I'd have no proof and people might not believe it. So maybe I'd just find my loved ones and acquaintances and greet them well once before everything's over.

Hope that is a satisfactory ANSWER.

In a dusty atmosphere it is sometimes POSSIBLE to see light TRAVELLING and it does appear to be moving in a straight line. The fact that light travels can be DEMONSTRATED by PUTTING an OBJECT in its path.

A vasectomy is a permanent severance of the vas deferens, which carries SPERM from the testes to the penis. A vasectomy is an OUTPATIENT procedure.



HOPE ITS HELPFUL

YES we can SAY ........

The differenceis a simple microscope has one lens where a compound microscope has an OBJECTIVE lens and an eyepiece with alonger focal length. ... Compund and even somesimple microscopes use a x10 MAGNIFICATION on the eyepiece that will reduce the LOSS of detail.A meniscus is just the center of SOMETHING

In EASY words we can say

VELOCITY is the SPEED with DIRECTIONS. where as speed do not have direction.
speed is a scalar quantity and velocity is vector quantity .

I HOPE I HELPED YOU....

Final Answer :


Steps:
1) Let break VELOCITY 'v' into two COMPONENTS.
will CONTRIBUTE in angular motion.
But, is parallel to ,and hence not contribute in angular velocity.

2) We have,


Hence,
The magnitude of Angular Velocity is

By the FORMULA v=u+at
as BODY is INITIALLY at REST u=0
v=0+8(5)=40m/s^2.

Application of refraction of light is a tool which helps us in understanding the basic concepts about the refraction of light and its application. First of all let us understand the basics of refraction of light and then we will study about application of refraction of light.

Generally refraction of light occurs when the waves travel s from ONE medium to another medium, with some refractive index and it generally enters other medium at oblique angle. There are various phenomenon’s associated with the refraction. Refraction of light has a major scope in case of optics and in the field of technology. For example, lens uses the basics of refraction of light to form an image of an object for various purposes, such as magnification. The other example is prism which also uses refraction to form a spectrum or band of colors from incident ray of light. In OPTICAL illusion and mirage, refraction generally plays a big role.

Various scientific things have been explained with the help of refraction. Day to day phenomenon’s are also explained with the help of refraction. One example which we are most familiar is ‘Twinkling of stars’. This phenomenon is explained in this way. The atmosphere which is blanket of earth actually consists of various layers of varying densities. It is because of change in temperature and pressure. The phenomenon is when the ray o f light enters into the layers of continuously increasing densities they are being refracted because of change in medium. In this complete process, ray of light follows curve path and hence it reaches to us. But because of the wind and currents, the density of the layer continuously increases and hence in turn the density of each layer goes on changing from layer to layer. And because of this at very small interval of time, the position of the image of start keeps on changing, and hence it ultimately PRODUCES the twinkle effect. This is all BASED on the concepts of refraction.

The same principle can be used to explain the apparent sunrise or sunset. The basic concepts of refraction are used to describe the complete process. The other applications of refraction are as follows:

1) Spear fishing, in which spear fisherman use a smart trick to catch the prey. The spear fisherman generally aims at a point below where the fish seems to be. This is because light actually changes its direction from one medium to another of different densities. This change is basically known as refraction.

2) Bending of stick in water. In water, a stick engrossed in water generally appears bent and small when viewed at an angle from above. This is also because the rays of light actually travel from water medium to air medium and hence in BEND away from the normal at the surface.

3) A coin appears raised in water. The same explanation exists.

From above discussion we have seen that refraction of light has been used to understand the scientific facts in almost all fields. This is all about application of refraction of light

Here is u r answer

Power density is a measure at the point of observation, often EXPRESSED by the INSTANTANEOUS Poynting vector. Hence gives information at the observation point.

Radiation INTENSITY on the other hand is a more normalized power density at the far field. Which thus gives information about the antenna source.

hope u UNDERSTAND plz mark as brain LIST

Boat has WIDER SURFACE, so the force from water helps it in FLOATING over water.
but nail has LOW surface and HIGH density, so it sinks in water.

HERE IS YOUR ANSWER

____________________________________
This possibly correct, this is because about 76.8% of electricity we use either comes from thermal power plants or HYDEL power plants depending upon the LOCATION.
In thermal power plants, fossil FUELS like coal, petroleum, and other fossil fuels are burnt to produce heat, which heats up water or a volatile liquid and the vapours used to turn turbines to generate electricity.
So if we conserve electricity, it avoids maximum utilisation of fossil fuels, therefore SAVING them too....

THANK YOU

If you don't MIND I want to say that you can purchase a science extra book from bookstore like rachna sagar TOGETHER CWITH science it can HELP you in this book so much extra questions are there it can help you

By FORMULA v=u+at
its velocity in X DIRECTION =20cos theta +0t=20cos 60°=10i.
its velocity in y direction=20sin60°-g(1)=20(√3/2)-10=10√3-10=10(√3-1)=10(0.732)=7.32j.
so velocity after 1sec=10i+7.32j

Here is UR ANSWER FRIEND

It -10/2
=-5m/sec sq.
HOPE THIS WOULD HELP

To have FRICTION .....

Covection MODE is BETTER for RICE..

These are the LAWS INVOLVED

No the TIME will not same if the DISTANCE is not is EQUAL

We ca't SAVE it is very difficlt

Average velocity = DISTANCE / Time
= 200 / 2
= 100 KM / HOUR

hiii friend

 initaial velocity of car(u)=50 m/s
                   
Final velocity of car(V)=20 m/s
                   
TIME(t)=3SEC
                   
Accleration[a]=?


We know that accleration=  (v-u)/t

                                        => ( 20-50)/3
                                                 
            
                                     =      ( -30)/3
                                                 

                                          => -10 m/s²

The input VOLTAGE is the voltage GIVEN to the TRANSFORMER and OUTPUT voltage is voltage gained from transformer

Glass is known to be TRANSPARENT MATERIAL because it pass light but ground glass is OPAQUE and white in colour because it not pass light THOUGH it

Actually we can SAY that all WAVELENGTHS have its UNIQUE colour and the SHORTEST wavelength has blue colour.
