modulation index is greater than , that MEANS the amplitude of the modulating wave is higher than that of the carrier wave. This CAUSES over- modulation of the carrier wave which RESULTS in distortion. Thus, a low modulation index is always maintained.Bandpass FILTER rejects low and high FREQUENCIES and allows a band of frequencies to pass through.

's law states that: The MAGNITUDE of the electrostatic force of attraction or repulsion between two point charges is DIRECTLY proportional to the product of the MAGNITUDES of charges and INVERSELY proportional to the square of the distance between them.The law was first published in 1785 by French physicist Charles - Augustin de Columbo.HOPE THIS ANSWER HELPS YOU…

take any two values. When current (I)=0.1 A, Volt (V) =0.5 VWHEN Current (I) =1 A, Volt (V)=5VV=IR =R Now, V1 = 0.5 V and V2 = 5 VI1= 0.1 A and I2 = 1 A=R =R=R5 = R

sical quantities those can be expressed in terms of FUNDAMENTAL physical quantities are called derived physical quantities. All the physical quantities of interest can be derived from the base quantities. The power (exponent) of base quantity that ENTERS into the expression of a physical quantity, is called the dimension of the quantity in that base. Broadly SPEAKING, dimension is the nature of a Physical quantity. Understanding of this nature HELPS us in many ways.

SizeAtomic size decreases on GOING ALONG a period from LEFT to right because the electron ENTERS into the same shell, therefore, ATTRACTION between nucleus and outermost electron increases and thus atomic size decreases.ValencyValency first increases from 1 to 4 and then decreases from 4 to 0 along a period from left to right. This happens because electron donating power increases and metallic character increases and then electron attracting power increases and non-metallic character increases.

your QUESTION ??

ng to right hand thumb rule if the direction of magnetic FIELD is CLOCKWISE then the direction of CURRENT is down to up and if the direction of magnetic field is anti clockwise then the direction of current is UPPER to lower direction

e here is ur answer.According to Einstein's theory, any massive body, including the Earth, produces this EFFECT. Inside the black hole, the flow of time itself draws falling objects into the center of the black hole. No force in the UNIVERSE can STOP this fall, any more than we can stop the flow of time.Hope it's HELP for you. Mark as a BRAINLIST.

context of CIRCULAR motion, LINEAR acceleration is also called TANGENTIALACCELERATION at. Linear or tangentialacceleration refers to CHANGES in the magnitude of velocity but not its direction. ... Centripetal acceleration acoccurs as the direction of velocity changes; it is PERPENDICULAR to the circular motion.

tion of waves has both a speed and a DIRECTION, called the velocity. The velocity of light changes depends on the MATERIAL it travels through. Light waves can be changed in a few different ways. Reflection is when the waves BOUNCE off a surface and CHANGE direction, like when they hit a mirror or POOL of water

hysical quantity which has its unit joule coulomb–1. ... Poetential is defined as work done per unitcharge. This implies, Joule per Coulomb is the SI unit of electric potential.2.Electron volt, unit of energy commonly USED in atomic and NUCLEAR physics, equal to the energy gained by an electron (a charged particle carrying unit electronic charge) when the electrical potential at the electronincreases by one volt. The electron volt equals 1.602 × 10−12 erg, or 1.602 × 10−19 joule. 3.1 μF (microfarad, one millionth (10−6) of a farad) = 0.000 001 F = 1000 nF = 1000000 pF. 1 nF (nanofarad, one billionth (10−9) of a farad) = 0.001 μF = 1000 pF. 1 pF (picofarad, one trillionth (10−12) of a farad)4.Equivalent parallel conductances. We can imagine a new conductance equivalent to the sum of the parallel conductances. It is equivalent in the sense that the same voltage appears.5.When capacitors are connected in series, the total capacitance is less than any one of the series capacitors' individual capacitances. ... If two or more capacitors are connected in parallel, the overall effect is that of a single equivalent capacitor having the sum total of the plate areas of the individual capacitors.5.Taking the three capacitor values from the above example, we can calculate the total capacitance, CT for the three capacitors in series as:One important POINT to remember about capacitors that are connected together in a series configuration, is that the total circuit capacitance ( CT ) of any number of capacitors connected together in series will always be LESS than the value of the smallest capacitor in the series and in our example above CT = 0.055μF with the value of the smallest capacitor in the series chain is only 0.1μF.This reciprocal method of calculation can be used for calculating any number of individual capacitors connected together in a single series network. If however, there are only two capacitors in series, then a much simpler and QUICKER formula can be used and is given as:If the two series connected capacitors are equal and of the same value, that is: C1 = C2, we can simplify the above equation further as follows to find the total capacitance of the series combination.Then we can see that if and only if the two series connected capacitors are the same and equal, then the total capacitance, CT will be exactly equal to one half of the capacitance value, that is: C/2.With series connected resistors, the sum of all the voltage drops across the series circuit will be equal to the applied voltage VS( Kirchhoff’s Voltage Law ) and this is also true about capacitors in series.With series connected capacitors, the capacitive reactance of the capacitor acts as an impedance due to the frequency of the supply. This capacitive reactance produces a voltage drop across each capacitor, therefore the series connected capacitors act as a capacitive voltage divider network.The result is that the voltage divider formula applied to resistors can also be used to find the individual voltages for two capacitors in series. Then:Where: CX is the capacitance of the capacitor in question, VS is the supply voltage across the series chain and VCX is the voltage drop across the target capacitor.

ll be experienced by the bricks ?The TWO bricks will experience an upward force which is DEPENDENT on the weight and volume of the two bricks. The upward force is called the buoyant force.The buoyant force is exerted by the water itself.What amount of water will be DISPLACED ?The amount of water that will be displaced is the volume of the brick that is immersed in water.This is according to the Archimedes Principle.Explanation :The bricks have DIFFERENT volume as specified in the question.Thus the brick with more volume will experience a GREATER force .The brick with less volume will experience a smaller force.The bricks will immerse if and only if the weight of the brick is more than the buoyant force.Otherwise they will float if the forces are equal.Hope it helps !__________________________________________________________
