<h3>Answer;</h3>
<em>A wave </em>
<em><u>A wave</u></em> is any form of a disturbance that carries energy from one place to another through a matter and space
<h3>
Explanation;</h3>
- Waves carry energy from one point, the source to another point or place. The transmission of a wave may occur through the space or through a material medium.
- Electromagnetic waves are those waves whose transmissions occurs through the space, they do not require material medium for transmission,for example, radio waves, while mechanical waves are those that require material medium for transmission, for example sound waves.
- The energy of wave depends on the frequency of the wave and the wavelength of that particular wave.
Answer:
Option B
Explanation:
Looking at the 3 galvanometer readings given above, for galvanometer A, the reading is -2 mA.

While for galvanometer C, the reading is -5 MA
Thus, option B is correct.
I'm a little confused by your question.
If you mean what is popular sovereignty, it is the belief that the governments is made and sustained by the consent of the people that it governs.
Speed v = initial speed u + acceleration a x time t
