What is the half-life concept in radioactive decay as tested in ESAT?
Answer: Time for half the nuclei to decay
Half-life is the time taken for half the radioactive nuclei in a sample to undergo decay.
Which type of electromagnetic radiation has the highest frequency?
Answer: Gamma rays
Gamma rays occupy the highest-frequency (and highest-energy) end of the electromagnetic spectrum.
A projectile is launched horizontally from a cliff. Which quantity remains constant throughout its flight (ignoring air resistance)?
Answer: Horizontal velocity
With no air resistance, the horizontal velocity is unchanged because no horizontal force acts on the projectile.
What does Faraday's law of electromagnetic induction state?
Answer: EMF is proportional to the rate of change of magnetic flux
Faraday's law states that induced EMF = -dΦ/dt, where Φ is the magnetic flux.
In ESAT Physics, what is the principle of superposition for waves?
Answer: The resultant displacement is the sum of individual displacements
Superposition states that when two or more waves overlap, the total displacement equals the algebraic sum of individual displacements.
What is the ideal gas law?
Answer: PV = nRT
The ideal gas law PV = nRT relates pressure, volume, moles, the gas constant R, and temperature.
