As, we know that in capacitive circuit, the output voltage lags behind input by tan inverse of( R/Xc). So option B is correct

Kirchhoff'scurrentlaw(1stLaw) states that current flowing into a node (or a junction) must be equal to current flowing out of it. This is a consequence of charge conservation.Kirchhoff'svoltagelaw(2ndLaw) states that the sum of all voltages around any closed loop in acircuitmust equal zero.

please like the solution 👍 ✔️

correct answer is

the correct ans is Mg/M+m+I/r²

sorry for above ans

Velocity of jet w.r.t. groundVjg= 450 km/h …...(Upward)

Velocity of products relative to jetVPJ= 1200 km/h …(downward)

Hence, velocity of products relative to ground = -1200+450

= -750 km/h

Here – ve sing means downward .

thanks bro

Thank you very much..

Velocity of car, u=100 km/hVelocity of bullet in opposite direction, v=250 km/hSince observer is on ground, so ,for him the velocity of bullet will be (v-u) =250-100=150 km/h

Second will have less reading as in second resistance are connected in series so resistance will be more so current will be less

now ammeter reading will be more in first X Circuitas there resistance are in parallel so less resistance and high current

Option (D) is correct.

A body can have multiple motions at the same time,

1) Wheels of a moving car it has circular motion and rectilinear motion

2 ) A bob of a pendulum has linear and periodic motion

Work done = Force× displacementW= 10× 2 =20 J.

thank you..

speed in x direction is dx/dt = 5*cos(10)t.10 = 50cos(10)t

speed in y direction is dy/dt = 5*10*-sin(10)t

so , speed is = √50²cos²(10t)+50²sin²(10t) = 50√2.

Hi..Thank you for your question.I will be happy to help you

Please give me some time to solve your problem

option b is your correct answer

Please let me know if you have any question regarding any steps provided in the solution

option b is the right answer

(m + 0.075)*1 *10 = (m+0.050)*1*7510m + 0.750 = 75m + 3.75065m = 3m = 3/65 kg

In a soap-and-water solution the hydrophobic (greasy) ends of the soap molecule do not want to be in the liquid at all. Those that find their way to the surface squeeze their way between the surface water molecules, pushing their hydrophobic ends out of the water. This separates the water molecules from each other. Since the surface tension forces become smaller as the distance between water molecules increases, the intervening soap molecules decrease the surface tension.

(C) is correct option

24*35=840.....1260-840=420

We know,Distance = Speed * Time

Distance covered by submarine = 350 - 100 = 250 m

Time taken = 10 sec

Therefore,Speed of submarine= Distance/Time= 250/10= 25 m/sec

We already know that electric dipole is an arrangement which consists of two equal and opposite charges +q and -q separated by a small distance 2a. ... Potential due to electric dipole does not only depends on r but also depends on angle between position vector r and dipole moment p.

For an isolated charge, the equipotential surfaces are co-centricsphericalshells and the distance between the shells increases with the decrease in electric field

The potential difference between two points ΔV is often called the voltage and is given by ΔV=VB−VA=ΔPEq Δ V = V B − V A = Δ PE q . The potential at an infinite distance is often taken to be zero. The case of the electric potential generated by a point charge is important because it is a case that is often encountered.

Fission, in biology, is the division of a single entity into two or more parts and the regeneration of those parts into separate entities resembling the original.

Maxwell's equationsare a set ofpartial differential equationsthat, together with theLorentz forcelaw, form the foundation ofclassical electromagnetism, classicaloptics, andelectric circuits. The equations provide a mathematical model for electric, optical, and radio technologies, such as power generation, electric motors,wirelesscommunication, lenses, radar etc. Maxwell's equations describe howelectricandmagnetic fieldsare generated bycharges,currents, and changes of the fields. One important consequence of the equations is that they demonstrate how fluctuating electric and magnetic fields propagate at the speed of light. Known aselectromagnetic radiation, these waves may occur at various wavelengths to produce aspectrumfromradio wavestoγ-rays. The equations are named after the physicist and mathematicianJames Clerk Maxwell, who between 1861 and 1862 published an early form of the equations that included the Lorentz force law. He also first used the equations to propose that light is an electromagnetic phenomenon.

The SI unit for permittivity isfaradpermeter(F/m or F. m−1).

The shape will be concentric spheres with centre at the charge .

The SI unit for permittivity is farad per meter (F/m or F. m−1). The lowest possible permittivity is that of a vacuum. Vacuum permittivity, sometimes called the electric constant, is represented by ε0and has a value of approximately 8.85×10−12F/m.

It's unit is C²N^−1M^−2 ( coulomb squared per Newton per square meter).
