Answer:
With his work, Maxwell unified electricity, magnetism and light, which are known as «Maxwell's synthesis.» Such a synthesis set a milestone in the history of the unification of forces that were so powerful that many nineteenth-century physicists thought the physical laws were already sufficiently comprehended.

hope this helps and can I get brainliest pls
Answer:
the answer is 10 w because it multiples 5x2 and the answer is 10 w because (w stands for work)
Answer:
Qh = -491.85J
(It is negative due to rejected heat)
Explanation:
In the question, the heat received by the refrigerator is at the cold reservoir where Qc= 415J
Now, we are looking for Qh.
Thus, using thermodynamics equation, we have;
Qc/Qh = — Tc/Th
Making Qh the subject, we obtain ;
-(QcTh)/Tc = Qh
Plugging in the relevant values, we obtain ;
-(415x320)/270 = - 132800/270 =
- 491.85J
Answer:
The amplitude of a sound wave is a reflection of how much energy is carried, which contributes to the intensity of the sound. Intensity is measured in decibels and is perceived as sound volume. Thus, the volume is proportional to the amplitude of the sound wave. The frequency of a sound wave is perceived as pitch.
Explanation:
In physics, there are empirical values for common important parameters. For example, the speed of sound is equal to 340 meters per second. Unlike the speed of light, the speed of sound is dependent on temperature and pressure. But in standard room conditions, the speed is 340 m/s. Using this value of speed, we can find the depth given the time. You should also note that the distance the echo travels is exactly the same distance that object travelled. Therefore,
Distance = 340 m/s * 6 seconds
Distance = 2,040 meters deep
