Explanation

 The unimportant factor in describing a satellite's orbit is the mass of the satellite. 

Explanation

The standard SI unit for magnetic dipole moment is the ampere-square meter (A⋅m²).

It can also be expressed in terms of energy and magnetic field strength, resulting in joules per tesla (J/T), which is equivalent to A⋅m². 

Explanation

The parameters that Kepler’s Law of period relates to are "the semi-major axis and the time period."

Explanation

In a stationary wave, the particle velocity at a node is zero.

Nodes are points of zero displacement in a stationary wave, and therefore, they do not oscillate and have no velocity. 

Explanation

Note According to KMU MDCAT answer key the correct answer is 'C'

A black body is an ideal radiator that radiates energy unequally at all wavelengths.

The intensity of radiation emitted by a black body varies with wavelength, following Planck's law.

The spectral distribution of this radiation is characterized by a peak wavelength that shifts depending on the temperature of the black body, which is described by Wien's displacement law.

Explanation

• Energy is measured in Joules (not Newtons).
• Force is measured in Newtons (not Joules).
• Velocity is measured in meters per second (m/s), not meters per second squared (m/s²), which is a unit of acceleration.

Explanation

An inductor stores energy in its magnetic field.

When current flows through the inductor, it generates a magnetic field around it, which stores energy.

Explanation

The resistance in an NTC (Negative Temperature Coefficient) Thermistor decreases with a rise in temperature.

This characteristic makes NTC thermistors useful for temperature sensing and control applications.

Explanation

A measure of the ability of a material to resist the flow of an electric current is called resistivity.

It quantifies how strongly a material opposes electrical conduction.

Explanation

A vehicle's battery is charged due to the chemical reactions between the electrodes and electrolyte inside it, which generate electrical energy.

This chemical effect is fundamental to the battery's ability to store and supply electrical power.
