The sun is a yellow dwarf star, so the correct answer is yellow. Hope it helps! If you could vote me brainiest, that would be awesome!
Answer:
<em>"the magnitude of the magnetic field at a point of distance a around a wire, carrying a constant current I, is inversely proportional to the distance a of the wire from that point"</em>
Explanation:
The magnitude of the magnetic field from a long straight wire (A approximately a finite length of wire at least for close points around the wire.) decreases with distance from the wire. It does not follow the inverse square rule as is the electric field from a point charge. We can then say that<em> "the magnitude of the magnetic field at a point of distance a around a wire, carrying a constant current I, is inversely proportional to the distance a of the wire from that point"</em>
From the Biot-Savart rule,
B = μI/2πR
where B is the magnitude of the magnetic field
I is the current through the wire
μ is the permeability of free space or vacuum
R is the distance between the point and the wire, in this case is = a
Answer:
he correct answer is Traffic accidents.
Explanation:
Chinese researchers have developed a car that needs the power of brain to operate. It is said to be country's first car that is operated by the mind. The researchers were worried due to the potential road accidents that was caused by the drivers distraction. They believed that concentration is required only while changing the lane or during turns (changing the moving status of car).
Radiation therapy can used in treating and destroying tumors in the human body, but it can also cause long-term damage to tissues if used incorrectly.<span> Radiation can be used in X-rays to detect broken bones and other internal damages.</span>
