HEYA MATE,

HERE IS UR ANSWER.

THANKS for asking this QUESTION.

T = 2v/g
2 = 2v/g
v = g
v = 9.8 m/s

v² - u² = 2aS
(9.8)² - u² = -2*9.8*40
u² = 9.8(9.8 + 80) = 880.04
u = 29.6 m/s

T = 2u/g
T = 2*29.6/9.8
T = 6.04 seconds.

As BODY has CONST velocity net ACCN is 0. So EQUATE net force to 0

The ERROR in MEASUREMENT of RADIUS is 0.001%.

Heyy..
Here is your answer.

》》The solar constant is a flux density measuring the total RADIATION energy received from the Sun per unit of time per unit of area and is meansured on a surface perpendicular to the rays, one ASTRONOMICAL unit (AU) from the Sun (ROUGHLY the distance from the Sun to the Earth).
The value of the constant is approximately 1.366 kilowatts per square meter.

The “constant” is fairly constant, increasing by only 0.2 percent at the peak of each 11-year solar cycle

Moreover, as the Sun BURNS up its
hydrogen , the solar constant increases by about 10 percent every BILLION years.

The approximate average value cited ,
1.3608 ± 0.0005 kW/m², which is 81.65 kJ/m² per minute, is equivalent to approximately 1.951 calories per minute per square centimeter, or 1.951 langleys per minute.


Hope it helps.
Thank you.

HEYA MATE,

HERE IS UR ANSWER.

Thanks for asking this question.

Electromagnet:-

This principle comes in very handy in the form of an electromagnet. An electromagnet is wire tightly wrapped around a ferromagnetic core. When the wire is connected to a battery, it produces a magnetic field that magnetizes the core. The magnetic fields of the core and the solenoid work together to make a very strong magnet. The best part about it is that the magnetic force stops when the electricity is turned off! Try it yourself with this experiment:

What You Need:
5 feet insulated copper wire
6-volt battery
large iron nail
PAPERCLIPS
What You Do:
1. Tightly wrap the wire around the nail to make a solenoid with a ferromagnetic core. If you have enough wire, wrap more than ONE layer. (If your nail fits inside the straw from the last experiment, you can use that solenoid instead of rewrapping the wire.)

2. Try to pick up some paperclips with the wire-wrapped nail. Can you do it?

2. Strip an inch of insulation off each end of the wire.



3. Hook up the wire to the battery and try again to pick up the paperclips with the nail. This time the electricity will create a magnetic field and the nail will attract paperclips! (Don’t leave the wire hooked up to the battery for more than a few seconds at a time – it will get HOT and DRAIN the battery very quickly.)

Experiment some more with your electromagnet. Count how many paperclips it can pick up. If you coil more wire around it will it pick up more paperclips? How many paperclips can you pick up if you only use half as much wire? What would HAPPEN if you used a smaller battery, like a D-size? Predict what you think will happen and then try it out!

I HOPE IT HELPS U.

Acceleration = Change in velocity ÷ time

In our case acceleration = 2

Our initial velocity = 6

We want to find the final velocity V

Our time is 6

6 = (V - 6) / 6

36 = V - 6

42 = V

V is thus 42 m/s

Hiiiii dear______


good evening_______________


___________________





Velocity is a vector QUANTITY, and average velocity can be defined as the displacement divided by the time. Consider coordinates for the center of circle to be (0,0), then COORDINATE for point A will be (0,1) and B will be (0,-1). Then

average velocity=displacement/time

=total displacement is 2M and time is 1 sec

average velocity=2 m/s

I didn't REALLY get your QUESTION. but still here it is
motion can be of three types
1- motion in 1D or motion in a straight line
2- motion in 2D or motion in a plane.
3- motion in 3D or motion in space.

Conditions
if a body CHANGES it's position with RESPECT to time, it is said to be in motion.

The sonochemical efficiency of a cylindrical sonochemical reactor has been investigated as a function of frequency and liquid height. The irradiation frequencies were 45, 129, 231 and 490 kHz. The liquid height was varied from 10 to 700 mm. The sonochemical efficiency of the cylindrical reactor was evaluated by potassium iodide (KI) dosimetry and calorimetry. In our study, the sonochemical efficiency depended on the frequency and liquid height; further, the plots of sonochemical efficiency against liquid height exhibit ONE or two PEAKS for each …

Let the body present at point A.

It COVERS whole park in 20s

In 20s it take = 1 round

In 1s it take = 1/20 round

In 70s take = 70/20 or 3.5 round.

Now, from moving point A, take ONE round, then the other and one more round and then a HALF round (.5 )

Here, you will stop at point B

On joining a kine we get a diameter.

As given radius was "R"

So, diameter or here displacement will be "2r"

Here is your ANSWER. 0.2 MM

An electromagnet is a TYPE of magnet in which the magnetic field is produced by an electric current. The magnetic field disappears when the current is turned off. Electromagnets usually consist of WIRE wound into a coil. A current through the wire creates a magnetic field which is CONCENTRATED in the hole in the center of the coil. The wire turns are often wound around a magnetic core made from a ferromagnetic or ferrimagneticmaterial such as iron; the magnetic core concentrates the magnetic flux and makes a more powerful magnet.

The main advantage of an electromagnet over a permanent magnet is that the magnetic field can be quickly changed by controlling the amount of electric current in the winding. However, unlike a permanent magnet that needs no power, an electromagnet requires a CONTINUOUS supply of current to maintain the magnetic field.

Electromagnets are widely used as components of other electrical devices, such as motors, GENERATORS, electromechanical solenoids, relays, loudspeakers, hard disks, MRI machines, scientific instruments, and magnetic separationequipment. Electromagnets are also employed in industry for picking up and moving heavy iron objects such as scrap iron and steel.

It has GREATEST speed before a bit before touching the SURFACE
and the smallest speed at the HIGHEST altitude

Let the train moving from Suraktal be A and the one moving from Shatabdi be B.

By the time train B is leaving, train A is (0700 - 0500) HRS ahead.

This equals to 2hrs.

In two hours train A has covered 2 × 15 = 30 km

Let the train meet at F a place xkm away from where A is after 2 hrs.

The distance covered by A will be xkm whereas the distance covered by B will be x + 30.

They take the same time to REACH F.

Time = Distance ÷ speed

X / 15 = (x + 30) / 20

20x = 15x + 450

5x = 450

X = 90km

Time taken by B = Time taken by A = 90 / 15 = 6hrs

The time the two meet is :

0700 + 6 = 1300 hrs

This equals to 1. 00 P. m

A boiler is a closed vessel in which fluid(GENERALLY water) is heated. The fluid does not necessarily boil. (In North America, the term "FURNACE" is normally used if the purpose is not to boil the fluid.[citation needed]) The heated or vaporized fluid exits the boiler for use in various processes or heating APPLICATIONS,[1][2]including water heating, central heating, boiler-based POWER generation, cooking, and sanitation.

Your QUESTIONS are GIVEN below you can do PRACTICE by SOLVING these questions

When a denser medium is kept between two parallel faces INSIDE a RARE medium and a ray falls UPON one of the two parallel faces reflects into the denser medium and COMES out of ANOTHER surface becoming parallel to the incident ray.

In the successive reflection the deviation at first surface is reversed at second surface but the emergent ray deviates literally.

The distance to what an emergent Ray devited from the direction of incident ray when suffers refraction at two parallel surfaces is called as lateral deviation/ displacement.

The lateral displacement/deviation increase with the increase in

• thickness

• angle of incident

• optical density

This is the RIGHT ANSWER......

We know, speed of light in VACCUM is 3 × 10^8 m/s . and speed of light decreases when it MOVES from rare medium to denser medium.

in CASE of rocket ship , use the formula,

where , is the initial length of rocket ship.
c is the speed of light .
is the final length of rocket ship.
v is the speed of rocket ship.

100/75 = 1/√(1 - v²/c²)
4/3 = 1/√(1 - v²/c²)
squaring both sides,
16/9 = 1/(1 - v²/c²)
16(1 - v²/c²) = 9
16 - 9 = 16v²/c²
7c² = 16v²
TAKING square root both sides,
√7c/4 = v
v = (3 × 10^8 × √7)/4
= 1.98 × 10^8 m/s

hence, speed of rocket is 1.98 × 10^8 m/s
