This your ANSWER of your QUESTION...

The FORCE APPLIED f by the athlete under steady speed is 518.76 N

Explanation:

The force f applied by the user has two components which are given by,

vertical component = f sinФ

horizontal component = f cosФ

In case of steady speed the NET horizontal force applied will be EQUAL to the FRICTION force.

Given friction force = 470 n,

Ф = load angle = 25°

Hence,

f cos 25 = 470

=> f = 470/cos 25

=> f = 470/0.906

=> f = 518.76 n.

Hence the total force applied under steady speed is 518.76 N.

It should be SOLVE like
3×10^5/5×10^5
3/5
0.6m
if I am right plz MARK me as BRAIN LIST

RAINDROPS start to form in a ROUGHLY SPHERICAL STRUCTURE due to the SURFACE tension of water. This surface tension is the "skin" of a body of water that makes the molecules stick together. The cause is the weak hydrogen bonds that occur between water molecules.

The purpose of an earth wire is to remove the excess charge or electrons from a circuit by moving them to ground.
LIGHTING detector is used to KNOW the intensity of LIGHTNING , so the PRESENCE of an earth wire will REDUCE its intensity and we can't detect the actual intensity, so an earth wire is absent in lighting circuit.

An electrolyte is BASICALLY a liquid with charged IONS to conduct electricity. So, all you have to do is get some DISTILLED water in a mug and TEST for conductivity. Since it doesn’t conduct at all, It’s a non-electrolyte.

Hey MATE here is your answer》》

With two eyes you can determine which objects are close to you and which are further away. Within certain linits you can even judge the DISTANCE that they are from each other, or how much further from you is one, more than the other.

Having the ability to measure distance. We can also determine aproximately how far a moving will travel in a given number of seconds. We call this the ability to judge speed. This gives is the ability to catch a baseball.

With only one eye, we can not do any of these things, unless we move and take a second reading from a second location. But with two eyes we constantly measure our world from two locations. And it becomes so easy that we think nothing of it.

Walk around your HOUSE and around your neighborhood, and play your favorite ball game with a comfortable bandage EVER one eye. Warning: don’t TRY driving your car.

⊙ A TYPE of electromagnet WHOSE purpose is to CONTROL the magnetic field.


⊙ It's purpose is to IMPOSE changes in electric current.

I WOULD rather say that for toppling to occur, the vertical(or mg) from the CENTRE of gravity should lie outside the body. The HIGHER the object ant the less area in contact of body with the plane, more the POSSIBILITY of toppling since for toppling, tan(theta) >= a/H

The wattage of an electrical INSTRUMENT contribute to the TOTAL cost of electricity.
The watt (symbol: W) is unit of Power. In the International System of Unit (SI) it is defined as DERIVED unit of 1 joule per second,and is used to quantify the rate of transfer of energy. In DIMENSIONS it is described by M L^2 T^-3

I. Without the absence of B/D relation the Kennedy THEORY it do not provide easy basis for fixing channel dimensions uniquely.

ii. PERFECT definitions of silt grade and silt charge are unavailable.

iii. PHENOMENON of silt transportation is not fully accounted and only critical velocity ratio (m) CONCEPT is considered sufficient which is wrong.

iv. No provision are there to decide longitudinal slope under the scope of the theory.

A PASSENGER CAR equilant is essential the empact that a mode of transport has on traffic variabls (such as speed,DENSITY) COMPARE to a single car for example typical values of PCU are

Given :

PROJECTION angle of the PROJECTILE = 30°

Momentum with which it is projected = p

To FIND :

Assuming no friction change in Kinetic energy when it RETURNS back to the ground = ?

Solution :

Since there is no friction , so we can apply Law of Energy CONSERVATION, i.e. Change in potential energy will be equal to change in Kinetic energy, so :

∴U = mgh

⇒ΔU =mgΔh

Since the projectile is back on the ground so Δh= 0

Hence ΔU = 0

Now since ΔU =  0 , so ΔKE should also be 0 .

So, when the particle returns back to the ground , its change in K.E. will be 0 .

This happens because of NEWTON's law that is.....

ACTION and reaction is equal and opposite

It means that when bullet is FIRED it's action and when gun receives a backward
KICK it is reaction.....

A BODY possesses ENERGY not only when it is in MOTION . when body is in motion then it has some finite amount of kenitic energy . but when it is not in motion, the body may possesses energy in the form of POTENTIAL energy.

ELECTROSTATIC SHIELDING is the PHENOMENON of protecting a CERTAIN region of space from external electric field . The electric field INSIDE a conductor is zero. ... No electrostatic potential is constant through out the volume of the conductor and has the same values as on its surface .

LET the point at HALF depth be X,

P1=P+dgx

Let the depth of lake be 2X,

P2=P+dg2x

P2=3/2×P1

2P2=3P1

2 (P+dg2x)=3 (P+dgx)

2P+4dgx=3P + 3dgx

P=dgx

x=P/dg

x=10^5/10000 (d=10^3kg/m^3) (P=10^5pa)

But depth of lake is 2x

2x=2×10=20m

ANSWER....


Four properties of the image formed by PLANE MIRROR are:-

1. it is ALWAYS virtual.
2. it forms erect images.
3. it is of the same size of the object.
4. it is placed at the same distance as the object is in FRONT of it.

The PRIMARY coil of step up transformer is made of thick copper WIRE because transformer the thicker wire is usually the ONE that carries a LARGER given by the ratio of the NUMBER of turns of the coil.

I think the data is not sufficient to find the distance from the top of the mercury to the top of the WATER column.. But this might HELP to solve further...(see image) sorry couldnt answer your QUESTION fully..

Instead of ANALYSING each passive element separately, we can combine all three together into a series RLC circuit. The analysis of a series RLC circuit is the same as that for the dual series RL and RC circuits we looked at PREVIOUSLY, EXCEPT this time we need to TAKE into account the magnitudes of both XL and XC to find the overall circuit reactance. Series RLC circuits are classed as second-order circuits because they contain two energy storage elements, an inductance L and a capacitance C

Nicol prism is a type of polarizer, an optical device made from calcite crystal used to PRODUCE and analyse plane polarized light. It is made in such a way that it eliminates one of the rays by total internal reflection, i.e. the ordinary ray is eliminated and only the extraordinary ray is transmitted through the prism. It was the first type of polarizing prism, invented in 1828 by William Nicol (1770–1851) of EDINBURGH. It consists of a rhombohedral crystal of Iceland spar (a variety of calcite) that has been cut at an angle of 68° with respect to the crystal axis, cut again diagonally, and then rejoined as shown, USING a layer of transparent Canada balsam as a glue.[1]

Unpolarized light ray enters through the left face of the crystal, as shown in the diagram, and is split into two orthogonally polarized, differently directed rays by the birefringenceproperty of the calcite. The ordinary ray, or o-ray, experiences a refractive index of no = 1.658 in the calcite and undergoes total internal reflection at the calcite–glue interface because its angle of incidence at the glue layer (refractive index n = 1.55) exceeds the critical angle for the interface. It passes out the top side of the upper half of the prism with some refraction, as shown. The extraordinaryray, or e-ray, experiences a lower refractive index (ne = 1.486) in the calcite and is not TOTALLY reflected at the interface because it strikes the interface at a sub-critical angle. The e-ray merely undergoes a slight refraction, or bending, as it passes through the interface into the lower half of the prism. It finally leaves the prism as a ray of plane-polarized light, undergoing another refraction, as it exits the far right side of the prism. The two exiting rays have polarizations orthogonal (at right angles) to each other, but the lower, or e-ray, is the more commonly used for further experimentation because it is again traveling in the original horizontal direction, assuming that the calcite prism angles have been properly cut. The direction of the upper ray, or o-ray, is quite different from its original direction because it alone suffers total internal reflection at the glue interface, as well as a final refraction on exit from the upper side of the prism.

Nicol prisms were once widely used in microscopy and polarimetry, and the term "using crossed Nicols" (abbreviated as XN) is still used to refer to the observing of a sample placed between orthogonally oriented polarizers. In most instruments, however, Nicol prisms have been replaced by other types of polarizers such as POLAROID sheets and Glan–Thompson prisms.

hope this answer will help you

Refractive index of glass prism = 1.5
SPEED of light in VACUUM = 3 × 108 m/s

∴ refractive index =
speed of light in vacuum / speed of light medium

⇒ 1.5 = 3×8 / x
⇒ x = 3 × 108 / 1.5
⇒ x = 2

∴ 2 × 108 m/s is the speed of WATER .

Hey Friend

✨Experiment 1✨

Take an empty soda bottle with minimum THICKNESS, open the CAP. Hold it in the mouth and suck all the air with a vacuum pump. What happens to the bottle ? The shape of the bottle will be altered. Why ? When we suck the air out of it, the air present outside the bottle will exert PRESSURE on the bottle in all possible directions. Therefore the bottle is crushed.

✨Experiment 2✨

Take a thin tin box with a SMALL opening at one end and hear it. When it is heated what happens ? We observe that the shape of the box is altered. Why ? I'm HEATING the air in the box will reduce and the walls of the box experiences pressure by the surrounding air, altering the shape of the box.

Hope it helps ☺☺☺

BEST OF LUCK ✌

G' = g - rω²Cos²θ

where θ is the latitude of the region, which ACTS as the ANGLE which is made by the point with the EQUATOR.

The range of Chennai is higher than the range of Trichy. Since the range is more and θ is small.

For Trichy, the θ will be high, and hence acceleration DUE to gravitation will be inadequate. And for Chennai θ will be small, therefore g' will be high and hence weight. This indicates in Chennai, the weight of the individual will be little more than the weight on Trichy.
