Explanation :

Kepler gives three laws of planetary motion :

First law :

First law is also known as the<em> law of orbits</em>. It states that all planets revolve in an elliptical orbit. The sun is present at one of its foci.

Second law :

Second law is also known as the<em> </em><em>law of areas</em>. It states that draw a hypothetical line from the midpoint of the sun to the midpoint of the planet. This will sweep out the same areas in identical interval of time.

Third law :

This is also known as the <em>law of periods</em>. It states that the square of the orbital time period (T) is directly proportional to the cube of semi-major axis (a).

i.e. T^2\propto a^3

So, Correct labeling is :

W: Third law

X: First law

Y: Second law

Hence, the correct option is (C).

There are three laws which are postulated by Kepler for planetary motion.

Kepler's first law: As per the first law of Kepler,the orbits of planets around the sun is elliptical in nature in stead of circular. The sun is situated always at one of its foci.

Second law: Planets are moving in such a way that the areal velocity of the planets are constant i.e planets sweep out equal ares in equal interval of time.

Third law: The square of time period of planets around the sun is directly proportional to the cube of semi major axis.

       Mathematically\ T^{2} \alpha\ R^{3}

where T is the time period and R is semi major axis.

Hence the correct answer to the question is C i.e third,first,second.

A parallel-plate capacitor is connected to a battery. What happens to the stored energy if the plate separation is doubled while
zlopas [31]

Answer:

new energy of the capacitor is half that of initial energy

Explanation:

As we know that the energy stored in the capacitor is given as

U = \frac{1}{2}CV^2

here we know that capacitance of parallel plate capacitor is given as

C = \frac{\epsilon_0 A}{d}

V = voltage of battery

so now we have capacitor remains connected to the same battery and the separation between the plates is doubled

so we have

C' = \frac{\epsilon_0 A}{2d}

so now the energy stored between the plates is

U = \frac{1}{2}(\frac{C}{2})V^2

so new energy of the capacitor is half

An ac generator consists of a coil with 40 turns of wire, each with an area of 0.06 m2 . The coil rotates in a uniform magnetic
mezya [45]

Answer:

d. 332 V

Explanation:

Given;

number of turns in the wire, N = 40 turns

area of the coil, A = 0.06 m²

magnitude of the magnetic field, B = 0.4 T

frequency of the wave, f = 55 Hz

The maximum emf induced in the coil is given by;

E = NBAω

Where;

ω is angular velocity = 2πf

E = NBA(2πf)

E = 40 x 0.4 x 0.06 x (2 x π x 55)

E = 332 V

Therefore, the maximum induced emf in the coil is 332 V.

The correct option is "D"

d. 332 V
