A balanced chemical EQUATION gives the identity of the reactants and the products as well as the ACCURATE number of molecules or moles of each that are consumed or produced. ... A stoichiometric quantity is the AMOUNT of product or reactant SPECIFIED by the coefficients in a balanced chemical equation.



Hope it HELPS you.

Work done by magnetic FIELD on CURRENT carrying CONDUCTOR. Suppose awire of length L carrying a current I is kept in a uniform magnetic field B perpendicular to the current. The force on the wire will be IBL and work done by magnetic force when wire MOVES a distance d along the force will be IBLd.

That is generally BCOZ of the low melting point and less RESISTANCE of the heater COIL whereas in a wire it has high melting point and high resistance.

HEY DEAR HERE IS YOUR ANSWER ✌✌❤❤

1 ) When two magnets are brought near each other, like poles REPEL; opposite poles attract.

2) When a MAGNET is brought near a piece of iron, the iron ALSO getsattracted to the magnet, and it acquires the same ability to attract other pieces of iron.

HEY DEAR HERE IS YOUR ANSWER ✌✌❤❤

We will KEEP the lens CLOSE to some page of a BOOK and see the print of the book through it. If the letters of the book appear ENLARGED, it is a convex lens and if they appear DIMINISHED, it is concave lens.

HOPE IT HELPS U.✌✌

Resistivity of a material is DEPENDS on its NATURE, TEMPERATURE and on other properties.

or we know

Resistance is proportional to L/A
so when we remove PROPORTIONALITY sign...

constant RHO comes= resistivity.

so resistivity is constant that's why it doesn't depends on any other factors.

A) BODY will GET retarded
b) bofy will get ACCELERATED

Answer:

Static friction is GREATER than kinetic friction because there are more FORCES at WORK keeping an object stationary than there are forces working to resist an object once it is in MOTION.

The fictitious Coriolis force can be used by ANYONE in that frame of REFERENCE to EXPLAIN why objects follow curved paths and allows us to apply Newton's Laws in non-inertial frames of reference. ... As on the merry-go-round, any motion in Earth's northern HEMISPHERE experiences a Coriolis force to the RIGHT.

The answer lies in the understanding of Archimedes’ Principle: a upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body DISPLACES and acts in the upward direction at the center of mass of the displaced fluid.

To FLOAT, the needle would need to displace its own weight of water but, as the volume of a needle is very SMALL, then so is the weight of water displaced and THEREFORE the upthrust (or buoyant force) is insufficient to support it.

On the other hand, a ship - whilst weighing many thousands of TONS - displaces a large volume (and therefore weight) of water. Hence the buoyancy force acting on the ship is much greater than the weight of the ship itself, making it to float on water.

“The density of nail (as of iron) is much larger than the water. So it sinks easily. The weight of the water displaced by the ship is equal to its weight, so it floats.Whereas the weight of the water displaced by the iron nail is less than its weight so the iron nail sinks”

It's generally coz of REFRACTION when u see

U can clearly see in the DIAGRAM we're I have EXTENDED the refracted Ray backward.

Because ELECTRIC FIELD lines emerges from positive charge and enters the negative charge so to check the electric field AROUND a charge we USE positive charge
hope it MAY help u

bcause in physics we have some CONVENTIONS which we have to FOLLOW .

sometime for our calculation to make easier we round off the values thats it ......but the original value of a particular THING remains same . we cant change the rules

not sure whether it is correct or not

It is the average DISTANCE between SUN and earth.
it is 150 MILLION KILOMETERS.

Answer:

A force is SAID to do work when it acts on a body so that there is a displacement of the point of application in the direction of the force. THUS, a force does work when it results in movement.

The work done by a constant force of magnitude F on a point that MOVES a displacement

Δ

x

in the direction of the force is SIMPLY the product

How can it be explained USING the LAWS of refraction that a LIGHT through optical centre of a LENS passes undeviated? If we assume the PORTION of the lens

No proceed of high to low no SMELL SPREAD of perfume large AREA this is example

I can't SEE the image but the LINE that is highest that Is nearest to DISPLACEMENT is the answer

Bcx if we use HARD iron core then it can't move the COIL in galvanometer. As a RESULT current not PASSED

Relation between force and acceleration==>>
F= ma
( let MASS as a constant)
Force is DIRECTLY proportional to the acceleration.

An important advantage of differentialoperation over single-ended is HIGHER IMMUNITY to “ENVIRONMENTAL” noise. For output stage a common sourceamplifiers has been USED, which is ABLE to provide a large gain in outputstage.

As we know that power is equal to V square/R so taking V as constant we can SAY that power is inversely PROPORTIONAL to RESISTANCE .So 4 ohm resistance will DISSIPATE more power .

It's so because radius is double of FOCUS that is f and C is CENTRE of CURVATURE then line joining c and p will be CALLED radius of curvature and
r


and r is equal to distance between c and p so the distance of c from p is 2f that's why it is mentioned as 2f.

This is because of the fact that phase TRANSITION occurs atsame temperature. Hence, ice at 1bar pressure will MELT to become liquidwater at 273K. Thus the latent heat of fusion is used which COMES to be around 335KJ/kg.

Rest and motion are RELATIVE because they DEPEND on the observe 's frame of reference....so if they two DIFFERENT OBSERVES are not at rest with respect to each other ,then they too get different result when they observe the rest or motion of the body

It MEANS the ratio of the net FORCE on the bodyand net MASS of the body is EQUAL to 3m/s^2.

U have to MENTION the TIME and VELOCITY at each time period to DRAW a CLEAR graph.

time period INCREASE as g is inversely PROPORTIONAL to T and g of MOON is 1/6 times of EARTH hence time period will increase by√6 times the initial

HOLA

=====================

The PRESSURE is more on standing because the WEIGHT increases on a particular spot but on lying weight increases everywhere so we CONCLUDE on standing pressure increases

=========================

HOPE U UNDERSTAND

A SHARP point means lesser area and lesser area means we need not to press hard in other words PRESSURE GETS REDUCED.

I have TRIED my LEVEL best if there's any mistake PLZZ UPDATE me

It will MASS × GRAVITATION = 69 ×10 = 690

The x RAYS is made up of cathode rays WICH are the MAIN cause or main SOURCE of cancer. i hope my answer HELPED you .

Generally their are two types of RAY's

Paraxial and marginal

Paraxial are those which on reflecting on the mirror converge at the focus.

Marginal Ray's are those which on reflecting on the mirrors converge at a POINT KNOWN as the FOCAL PLANE.

Hey bro here is your answer...
the WATER will comes into its normal TEMPERATURE if you left the HOT water in the room for ONE HOUR.

Friction is a kind of FORCE so we can say that more the MASS of the OBJECT or more the weight of the object more will be the friction
