o's law. Avogadro's law, a statement that under the same CONDITIONS of temperature and pressure, EQUAL volumes of DIFFERENT gases CONTAIN an equal NUMBER of molecules. This empirical relation can be derived from the kinetic theory of gases under the assumption of a perfect (ideal) gas.please mark me as brainliest..

your QUESTION is INCORRECT.

rddddddssssssssssssssssssssssssssssssssssss

is important DUE to the following: -1) Forests gives us the supply of OXYGEN, which essential for human being. 2)Forests are made up of Millions of tree which gives a variety of wood like rose, saddle teak wood by which furniture are made. 3)Forests is the home to millions of animals, birds. And is the only HABITAT in which animals can live or survive. hopefully it may help you all please follow

it HELPS. ACCORDING to me this is only the ANSWER.

5 The name of the ELEMENT is Boron The atomic no. is 5 The no. ELECTRONS = 5 Electronic CONFIGURATION = 2,3 So, the VALENCY of the element, Boron is 3⁺

above relation you can see that AREA of the CONDUCTOR and resistance are inversely PROPORTIONAL. Hence if area of the conductor of increased, resistance of the conductor decreases, therefore LOSSES (COPPER loss) decreases. This is the relation between conductor size, voltage and current. mark as bainliest

tic compass uses the poles of our planet to stay in alignment. A Gyroscopic compass is set to a particular direction and tends to try to stay that way. After time, even the best Gyro will start to process (move). This means the you will need to compare your Gyro to the magnetic every 15 minutes or so. Some modern gyroscopic compasses are capable of auto RESETTING to do this UPDATE AUTOMATICALLY

a substance causes molecules to speed up and spread slightly further apart, occupying a LARGER volume that results in a DECREASE in density. ... Hot WATER is less DENSE and will float on room-temperature water. Cold water is more dense and will sink in room-temperature water.

ewable resources :the sources which cannot be RENEWED so FASTLY are called non RENEWABLE resources.on of the non renewable resources are fossil fuels it take millions of years to get them back such as petrol.if the  crude oil has been extracted totally from a CERTAIN place it takes a long time time to form the crude oil from dead animal. so the fossil fuels under the non renewable resources category

ls Required:A sonometerA set of eight tuning forks1/2 kg hangerSeven 1/2 kg slotted weightsRubber padPaper riderMeter scaleScrew gauge.The Procedure: We'll place the sonometer on the table.Test the pulley and if you experience any friction, make it frictionless by oiling it.Place a suitable maximum weight in the hanger.Move the wooden bridges P, outward to include maximum length of wire (AB) between them.Take a tuning fork of least frequency from among the set, STRIKE its prong with a rubber pad to make it vibrate. Bring the tuning fork near your ear.Pluck the wire AB from the middle and leave it so that it vibrates.Listen to the SOUND produced by the tuning fork and wire and judge which has less frequency.Since the LONG wire may have less frequency, decrease its length by moving the bridges inward and check the frequencies again.Go on decreasing the length till frequency of the vibrating wire AB becomes equal to the frequency of the tuning fork.Put an inverted V shape paper rider R on the wire AB in its middle. Vibrate the tuning fork and touch the lower end of its handle with sonometer board. The wire AB vibrates DUE to resonance and paper rider falls.Note the length of the wire AB between the edges of the two bridges and record it in 'length decreasing' column.Bring the two bridges closer and then adjust the length of the wire by increasing it little by little till rider falls.Note the length of the wire and record it in the 'length increasing' column.Take the remaining five tuning forks, one by one, in order of increasing frequency and repeat steps 5 to 13.Record your observations.

,DIFFERENTIATE the given EQUATION w.r.t. t(time)….dx/dt=0+7+(2×10)t^2-1dx/dt=20t+7since,dx/dt=INITIAL velocityTherefore, The initial velocity: v=20t+7 m/s

e KNOW as voltage is constant to every device CONNECTED in PARALLEL to the source .In this CASE only current divides .To maintain the same required voltage across the electrical APPLIANCES they are connected in parallel to the source supply

YOUR ANSWER MY FRIENDS

ke VOLTMETERS, AMMETERS tend to influence the amount of current in the circuits they're connected to. HOWEVER, UNLIKE the ideal voltmeter, the ideal ammeter has zero internalresistance, so as to drop as little voltage as possible as electrons flow through it.

s generally in motion and POSSESS KINETIC energy . It is used for bathing,washing etc.Hope it HELPS U.

AND DIGITAL QUANTITIES— Ananalog signal is sampled or tested repeatedly over APERIOD of time to DETERMINE the characteristic thatcontains  the  analog  quantity.  The  sampled  analog  valueis converted to the nearest binary value or quantity. Thebinary value is then encoded into a CODE acceptable tothe digital equipments that use the data. Standardizedbinary   words   called   BAMs   (binary   angularmeasurement) are used to transmit angular, range, andheight VALUES between digital equipments in shipboardcombat direction systems. Other coding systems suchas GRAY code or binary-coded decimal (BCD) are alsoused to transmit converted values

because the moon MOVES in elliptical orbits AROUND the Earth , hence when it closest to Earth it looks ENLARGED and SHRUNK when it far from Earth

aw of REFRACTION state that incident ray , refracted ray and the normal at the point of INCIDENCE all lies in a same PLANE. second law of refraction state thatangle of incidence and ANGLE of refraction is constant which is also known as Snell's law. Snell's law, which states that, for a given pair of media, the ratio of the sines of the angle of incidence θ1 and angle of refraction θ2 is equal to the ratio of phase velocities (v1 / v2) in the two media, or equivalently, to the INDICES of refraction (n2 / n1) of the two media.

first law :Newton's First Law states that an object will remain at rest or in uniform motion in a straight line unless acted UPON by an external force. A LUGGAGE is usually tied with a rope on the roof of BUSES. When a moving bus suddenly stops, the luggage on its roof tends to continue in the state of motion due to INERTIA of motion. Hence the luggage fall down from the roof of the bus. Similarly, when a bus suddenly starts, the luggage on the roof of the bus tends to continue in the state of rest and hence fall down from the roof of the bus. Thus, to avoid the FALLING of the luggage, it is tied with a rope on the roof of a bus.

r the basic definition of a derivative according to Leibniz:ddxf(X)∣∣x=x0=limx→x0f(x)−f(x0)x−x0ddxf(x)|x=x0=limx→x0f(x)−f(x0)x−x0From this you SEE that if f(x)f(x) has unit uu, and xx has unit vv, the derivative has unit uvuv.More generally, the nn-th derivative dndxnf(x)dndxnf(x) has unit uvnuvn (this is easily shown by repeating the above argument).EDIT: In ADDITION to the MATHEMATICS consider a basic example: let a function s(t)s(t) denote the distance travelled by a car versus time, i.e. s(t)s(t) has unit meters mm and the time tt has unit SECONDS ss. The first derivative then has unit m/sm/s and descibes the velocity=distance per time. The second derivative has unit m/s2m/s2 and describes acceleration, which is [change in velocity] per time.Translated to your graph, the first derivative corresponds to [change in gap probability per height] or [slope of gap probability]. The sought second derivate then denotes [change in [slope of gap probability] per height]
