Answer:
The sentence that describes the movement of matter and energy in the water cycle is:
C. Energy from sunlight warms the ocean surface and causes water to evaporate.
Explanation:
In the water cycle, energy from sunlight plays a crucial role in causing water to evaporate from the ocean surface. This evaporation process occurs when the sun's energy heats up the water, increasing its temperature. As a result, the water molecules gain enough energy to break free from the liquid state and transform into water vapor, which rises into the atmosphere. This step represents the movement of both matter (water) and energy (sunlight) in the water cycle.

B. If two out-of-phase waves arrive simultaneously at a point, their amplitudes add up.
C. If two in-phase waves arrive at a point one after another, their amplitudes add up.
D. If two out-of-phase waves arrive at a point one after the other, their amplitudes adds up
The superposition principle states that when two in-phase waves arrive simultaneously at a point, their amplitudes add up.
The correct statement that describes the superposition principle is option A: If two in-phase waves arrive simultaneously at a point, their amplitudes add up. In-phase waves have the same frequency, wavelength, and direction. When two in-phase waves meet, the amplitude of the resultant wave is the sum of the individual amplitudes.

The two variables that affect current in a circuit according to Ohm's law are voltage and resistance. If voltage increases, current increases assuming resistance remains constant. Conversely, if resistance increases, current decreases.
According to Ohm's law, the two variables that affect the amount of current in a circuit are voltage and resistance. If the voltage in a circuit is increased, according to Ohm's law, so is the current, providing the resistance doesn't change. On the other hand, if the resistance in a circuit is increased, the current is reduced.
For instance, if we consider a simple electric circuit with a battery and a light bulb. If the voltage of the battery is increased, more current will flow, and the light bulb will shine brighter. However, if the resistance (for example by adding another light bulb in series) is increased, less current will flow, and the bulbs will be dimmer.

B) As the frequency of the wave fluctuates, its energy decreases.
C) As the frequency of the wave increases, its energy also increases.
D) As the frequency of the wave changes, its energy remains constant.
As the frequency of the wave increases, its energy also increases. The correct option is C.
The frequency of an electromagnetic wave is defined as the number of oscillations or cycles per unit of time.
The frequency of the wave, on the other hand, is directly proportional to energy.
The energy of an electromagneticwave is precisely proportional to its frequency, according to the equation E = hf, where E represents energy, h is Planck's constant, and f is the frequency of the wave.
Simply said, higher frequency waves have more energy than lower frequency waves.
This is true over the whole electromagneticspectrum, from radio waves to gamma rays. The energy carried by the wave rises as the frequency of the wave increases.
Thus, the correct option is C.
