All accelerated charges radiate. We know that an electric current in a conductoris simply a mass migration of free electrons. If the current is alternating, as in an antenna, the free electrons in a GIVEN locality move back and forth in unison. So EVERYTHING that conducts alternating current acts as an antenna. The essential thing is that antenna will radiate Energy (as emwaves). To radiate any significant amount of energy, theantenna has to be a 'reasonable' size compared with the wavelength. In antenna you have to transfer power (the energy is contained involtages and CURRENTS) into electromagnetic RADIATION (where the energy is contained inthe E- and H-fields) travelling away from the antenna. We have a classical understanding (the WAVES leave one antenna and eventually encounter another receiver antenna)

=

u = 0 m/s

V = 72 km/h = 72 *5/18 m/s

= 20 m/s

t = 20 s

As v = u + a t

so, 20 = 0 + a * 20

so, a = 20/20 = 1 m/s^2

Now mass = 1000 kg

a = 1 m/s^2 and

Force, F = ma

so, F = 1000 * 1 = 1000 kg m/s^2

= 1 kN

Water is a DIELECTRIC.it can ABLE to withstand certain amount of v or i.but during lightning high VOLTAGES are shred so there will be dielectric breakdown causing intense CURRENT heat etc.

The FACES and edges SELECTED the move TOOL ACTS similar to the push/pull

s = UT + ½at²

u = initial velocity = 0,

along x-axis => sₓ = 0t + ½at² = 3(4)² = 48 m (in the +TIVE direction)

along y-axis => sᵧ = 0t + ½at² = 4(4)² = 64 m

distance from origin = d = √ [(sₓ)² + (sᵧ)² = √ [(48)² + (64)²] = √[6400] = 80 m

Hey mate

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

Laser is a related to radiation of light .its STAND for “light amplification by simulated emission of radiation”. There is

Light means-light is electromagnetic radiation within a certain portion of the electromagnetic spectrum .in simple word a thing that makes visible to anything, that's known as light.

Amplification -the action of enlarging upon or adding detail to a STORY or statement.

So ,laser is a device that EMITS a BEAM of coherent light through an optical amplification process. There's many types of laser like gas laser ,fiber laser, diode laser etc. It is used in MEDICAL ,military, eye surgery,traffic, communication etc.

Average SPEED is 60 km/h and total distance is 120 km
so total time taken is 120/60=2 hr
now distance covered in 1 ST HOUR is 30 km
remaining distance is 90 km
and time 1 hr
so speed for NEXT hr=90 km/hr

Hii There!!


A SPRING exerts FORCE on OBJECTS ATTACHED to it's ends when it is COMPRESSED or extended (pushing or pulling).


Hope it helps

Looking at this system we find that :

The length is in meters.

The The time is in SECONDS.

This clearly shows that the system of MEASUREMENT follows MKS which is measured in meters, Kilograms and Seconds.

The force is also in Newtons which is given by Kgm/s².

The mass is THUS measured in Kilograms.

Here is the ANSWER for QUESTION you ASKED..

As a general rule, the number of images will be ONE less than the VALUE 360÷x where x is the angle between two mirrors. (Assuming one edge touching each other)

Eg.

●Suppose the angle of inclination between mirrors is 120 degree.

360÷120 GIVES 3

Out of 3 parts, one is the OBJECT itself. So the images formed will be 3 - 1 = 2

●Suppose the angle of inclination between mirrors is 100 degree.

360÷100 gives 3.6

Out of 3.6 parts, one is the object itself. So the images formed will be 3.6 - 1 =2.6

This means two complete images and the third IMAGE will be seen as only 60% part of the complete object.

As many of the other answers say, it will go on
swinging forever, provided that there are no
friction losses or MAGNETIC or electrical
interferences.
It doesnt mean that you can extract infinite
energy out of the pendulum. The pendulum has
a fixed amount of energy. All that is happening
is the energy GETTING converted from potential
energy to KINETIC energy during the oscillation of
the pendulum, Once you start extracting energy,
the pendulum SLOWS down, and ultimately stops.
Sorry to tell you this, but almost all those
'infinite energy' ideas have logical loopholes in
them.. I havent come across a really good one
yet......

In the back WARD direction!!!
PLEASE MARK it as a brainliest friend

HII..
Here is your ANSWER..

=>Average velocity can be defined as the Displacement divided by the time.

=>We can ALSO say that it is the RATE at which an object changes its position from ONE place to another.

=>Average velocity is the vector quantity.

=>It's SI UNIT is m/s.

Hope it helps uh....✌️✌️✌️

Because the AIR MOVES out of BALLOON through the HOLE in them

BATTERY is CONNECT NEGATIVE TERMINAL to POSITIVE terminal

Distance=SPEED × time
speed=92.4 kmph
time=20 mins=20/60 hrs =1/3 hrs
time NEEDED to be converted into hrs as speed is GIVEN in hrs format.
distance = 92.4 km / hrs×1/3 hrs
=92.4/3 KMS
=30.6 kms

don't ASK SIMPLE QUESTION MAN it is very EASY

A is EQUAL to TOTAL DISTANCE COVERED by ROAD distance
