Answer:
The magnetic field 50m below the transmission line is 4 micro Tesla.
Explanation:
The magnetic field due to a current carrying wire at a distance is
where is the magnetic constant.
For the case of the power line we put in and to get:
.
Thus, the magnetic field 50m below the transmission line is 4 micro Tesla.
<span>Some geographic areas endure cycles between these two processes called transgressive-regressive sequences. The rocks of western Pennsylvania are one example. Sandy beaches often leave observable records of transgression by covering marsh sediments that were once behind it as it moves inland. The original sediments are then covered by even deeper water sediments, which geologists can trace and record. It is generally believed that transgression will increase in accordance with rising sea levels worldwide</span>
Answer:
<h2>Equilibrium</h2>
Explanation:
The pendulum is at rest ( or balance due to the equal action of opposing forces).
If two sources emit waves with the same wavelength and a constant phase difference ϕ, they are said to be coherent.
<h3>What is coherent source ?</h3>
- If the frequency and waveform of two wave sources are the same, they are coherent. Waves' optimal quality of coherence makes stationary interference possible.
- When the phase difference between two beams of light is constant, they are coherent; if the phase difference is random or changes, they are noncoherent.
- The concept of a superpositioning at the core of quantum physics and quantum computing is referred to as "quantum coherence." Quantum coherence specifically considers a scenario in which a wave property of an item is split in two and the two waves coherently interfere with one another.
- The interference visibility, which examines the size of the interference fringes in relation to the input waves, is an easy way to measure the degree of coherence; correlation functions provide a precise mathematical definition of the degree of coherence.
