Given:

4m was the initial length.

Length change = 40 cm = 0.4 m

Elongation as a percentage =?

The formula

In order to determine the percentage elongation, we must divide the wire’s length change by its initial length and then multiply the result by 100. Thus,

(Length Change / Original Length) × 100 = Percentage Elongation

Elongation percentage = (0.4 / 4) × 100

= 0.1 × 100

= 10%

Only waves that are transverse can become polarized. Polarization cannot occur in longitudinal waves. Light is a transverse wave because it can become polarized.

In conclusion, although diffraction, interference, and refraction are all phenomena that show that light is a wave, they do not in and of themselves establish that light waves are transverse waves. Wave optics, which includes both longitudinal and transverse waves, provides a more comprehensive framework for understanding each of these phenomena.

Vs = 12V, Vp = 240V

VsIs = Pout

30W = 12V × Is

IS equals 2.5 A.

Ip / Is = Vs / Vp

VpIp = VsIs

12 × 2.5 = 240 Ip

Ip = 30/ 240

Ip = 0.125 A

Option A is correct because this is a numerical question with only one possible response.

In essence, TVs provide us with images by projecting electron beams onto a screen. However, placing a magnet close to a television would create a magnetic field that would cause the electron beam to change direction.

The force acting on an object for a brief moment is referred to as an impulse. Ns (newton-second) and kgm/s (kilogram meter per second) are among its units.

This formula can be used to calculate it: ΔP = ΔF x t

Let resistance, inductance, and capacitance be represented by the voltages V1, V2, and V3. Source Voltage (V) can then be expressed as follows:

Shock waves are the main waveforms produced by explosions, but depending on the type of explosion and the medium the waves travel through, they can also produce other kinds of waves. Thus, it is accurate to state that shock waves, longitudinal waves, and transverse waves can all result from explosions.
