Answer: c. A person who gains unauthorized access to digital data
Explanation:
Before solving this, you must know the definition of these units of measurement. Watt is a measurement of power which is the amount of energy per unit time in seconds. Energy, on the other hand, is expressed through the SI unit Joules. Thus, power is the amount of energy in Joules per second.
From here, you can use the dimensional analysis technique. Also, you should know that 1 kilowatt is equal to 1000 watts, and 24 hours is equal to 86,400 seconds. Then,
100 = Energy/86,400
Energy = 8,640,000 Joules
The correct answer is A.
The coefficient of absorption of material A is 30%. So, the material will absorb 30% energy of the incident wave falling on it. Thus, the reflected wave will carry the rest 70% energy.
The coefficient of absorption of material B is 47%. So, the material will absorb 47% energy of the incident wave falling on it. Thus, the reflected wave will carry the rest 53% energy.
The coefficient of absorption of material C is 62%. So, the material will absorb 62% energy of the incident wave falling on it. Thus, the reflected wave will carry the rest 28% energy.
Hence, material C would be the best, because the percentage of the energy in an incident wave that remains in a reflected wave from this material is the smallest.

Answer:
Magnetic Field Strength
Explanation:
The effect of the splitting of the spectral lines of an atom into several of its components when a static magnetic field is present is referred to as Zeeman Effect.
The spectral lines here corresponds to the various discrete energy levels in the sun at which the emission and absorption of the different energy levels of the sun occurs.
The splitting of the spectral lines occurs due to the presence of the strong magnetic field on the surface of the sun.
Thus the Zeeman Effect is used to measure the magnetic field strength on the sun's surface.
