Physics and Electrical Engineering Quiz

Which of the following gates is considered a universal gate in digital electronics?

According to classical theory, what was Rutherford's atom?

In thermodynamics, the Zeroth law is related to:

If an electromagnetic wave is described by the function $E = E_0 ext{sin}(rac{2 ext{π}x}{λ} - 2 ext{π}ft)$, then:

From the given graph of electric field variation between two charges, which statement is correct?

If a constant voltage is applied between the two ends of a uniform metallic wire, when will the heat developed double?

Digital Electronics

The NAND gate is known as a universal gate as it can be used to construct any other gate (AND, OR, NOT).

Classical Theory of Atom

Rutherford's atom model proposed that an atom consists of a small, dense nucleus surrounded by orbiting electrons, resembling a miniature solar system.

Thermodynamics

The Zeroth law of thermodynamics establishes thermal equilibrium and the concept of temperature, stating that if two systems are in thermal equilibrium with a third system, they are in equilibrium with each other.

Electromagnetic Waves

The equation (E = E_0 \sin\left(\frac{2\pi x}{\lambda} - 2\pi ft\right)) describes the electric field component of an electromagnetic wave, where (E_0) is the amplitude, (\lambda) is the wavelength, and (f) is the frequency.

Electric Field Variation

To accurately assess statements regarding electric field variations between two charges, consider factors like charge magnitude, distance, and the arrangement of the charges.

Heat Development in Conductors

In a uniform metallic wire, if a constant voltage is applied, the heat developed will double if the time duration is doubled, given that heat production is proportional to time in a resistive circuit.
