Physics: STD.XII Chapter 10 NAVNEET 21 M.L.Q.SETS Quiz

A quantity that changes in a wave-like pattern over time.

It emits radiation across all frequencies of the electromagnetic spectrum.

It produces a LOW output only when ALL of its inputs are HIGH.

It uses hydraulic pressure exerted on oil within cylinders to lift heavy objects.

In simple harmonic motion, the total energy of a particle is determined by its mass and acceleration.

The time it takes for half of the radioactive nuclei in a sample to decay.

A phasor represents the sinusoidal variation of a quantity over time. It's a way to depict the amplitude and phase of the wave.

A blackbody is called a full radiator because it emits radiation at all frequencies of the electromagnetic spectrum. It's a perfect emitter.

A NAND gate outputs a LOW signal only when all of its inputs are HIGH. It's a combination of AND and NOT operations.

A hydraulic lift utilizes the principle of transmitting pressure through an incompressible fluid (oil) in cylinders to lift heavy objects.

The total energy in simple harmonic motion (SHM) can be expressed as E = (1/2) * m * ω² * A², where 'm' is the mass, 'ω' is the angular frequency, and 'A' is the amplitude.

If the half-life of a radioactive element is 100 days, it will take 175 days for 87.5% of the initial nuclei to decay. This is because each half-life reduces the amount by 50%.
