In the electromagnetic wave spectrum, wavelength and frequency have an inverse relationship.

Appropriate Choice: A
Since a multimeter is a test instrument used to measure two or more electrical values, primarily voltage, current, and resistance, this choice is accurate.

45J, or 45/60×100, or 75%, is ejected to the cold reservoir if the work is 15J out of 60J.

Area of the cross-section A=π(d/2)2=π(0.05 mm/2)2=π×0.0025mm2 /4 ≈0.00196 mm2
This wire has the smallest cross-sectional area because it has the smallest diameter of any of the available options. As a result, under the same tension, it will extend to its maximum.

One H2O molecule has an average mass of 18.02 amu. Both the number of atoms and the number of moles are precise numbers that have no bearing on the number of significant figures. One mole of H2O weighs 18.02 grams on average. The molar mass of water is 18.02 g/mol, or 0.018 kg/mol, according to the statement.

The rate at which an object’s velocity changes in relation to time is called acceleration. It is calculated by dividing the velocity change by the time it takes for the change to occur. The SI unit of acceleration is meter per second per second (m/s2) since the SI unit of velocity is meter per second (m/s) and the SI unit of time is second (s).

The process by which unpolarized light becomes polarized is known as polarization of light. Only one plane is vibrated by polarized light. The magnetic and electric components of light waves vibrate perpendicular to each other, making them transverse waves. Light only vibrates in one plane when it is polarized. Therefore, light’s polarization indicates that it is electromagnetic.

The particle’s direction is always relative to the lines of the electric field.
