Which type of radiation produces a wave and a lot of energy?A. GammaB. AlphaC. BetaD. Zeta
Kobotan [32]

The correct answer is option A.

The Gamma waves emitted from radioactive decay have a frequency of around 10¹⁹ Hz, which is much greater compared to the alpha of beta waves.

The frequency is directly proportional to the energy of the waves as given by the equation,

E=hf

Where E is the energy, h is the Planck's constant, and f is the frequency.

Thus the gamma waves have a lot of energy compared to the other options.

Thus the correct answer is option A.

How much energy is dissipated as heat during a two-minute time interval by a 1.5- kΩ resistor which has a constant 20- V potenti
lord [1]

Answer:

32 J

Explanation:

Power is V²/R = 20²/1500 = 4/15 . . . watts

In 120 seconds, the energy is ...

(4/15 J/s)×(120 s) = 32 J

In a 2-minute period 32 joules are dissipated as heat.
