Explanation

Instantaneous velocity at any point on a curved path is directed tangentially to the curve.

It indicating the direction of motion at that moment.

Explanation

Electric generators and transformers are based on the principles of Faraday's law.

This law explains electromagnetic induction, where a changing magnetic field induces an electric current.

Explanation

Batteries with different EMF cannot be connected in parallel because KVL is not valid in this case.

Connecting such batteries can lead to excessive current flow and potential damage.

Explanation

 Both Hay’s bridge and Maxwell’s inductance capacitance bridges are used to measure the inductance.

Hay’s bridge is used for the measurement of inductance of high Q coils

whereas Maxwell’s inductance capacitance bridge is used for the measurement of inductance of low Q coils.

Explanation

Indicate high-frequency electromagnetic waves:

Adiabatic Process:

An adiabatic process is one in which there is no heat exchange with the surroundings. When a tire bursts suddenly, the air inside the tire expands rapidly without any heat transfer to or from the surroundings.

This rapid expansion without heat exchange is characteristic of an adiabatic process.

Expansion:

The bursting of the tire leads to a sudden increase in volume, which is an expansion process.

Explanation

In quantum mechanics, an electron in a one-dimensional infinite potential well (also called a "quantum box" or "particle in a box") has discrete energy levels given by:

$$E_n = frac{n^2 h^2}{8mL^2}$$8mL^2​

Where:

• $n$ = quantum number (for ground state$n=1$)

• $h$ = Planck’s constant

• $m$ = mass of the electron

• $L$ = width of the box

▶ These energy levels depend only on the physical parameters (like mass, size of the box), not on temperature.

The ground state energy (lowest possible energy) is:

E1​=h^2/8mL^2​

Explanation

The de-Broglie wavelength (λ) is given by the formula:

λ = h / (m × v)

Where:

h = Planck's constant = 6.626 × 10^-34 J s

m = mass of the particle = 10^-30 kg

v = velocity of the particle = 10^6 m/s

Substituting the values, we get:

λ = (6.626 × 10^-34 J s) / (10^-30 kg × 10^6 m/s)

= (6.626 × 10^-34 J s) / (10^-24 kg m/s)

= 6.626 × 10^-10 m

So, the de-Broglie wavelength associated with the particle is 6.6×10^-10m.

Explanation

According to Maxwell's equations, the speed of light in free space is independent of frequency. 

Maxwell's equations predict that light is an electromagnetic wave, and its speed in a vacuum is a constant value, regardless of the frequency of the wave.
