Answer:
Explanation:
The wire in the windings needs to be insulated. Electricity takes the shortest path from one place to another. If the wire is bare, then adjacent turns are touching. The result is the current flows through the shortest path between the leads of the electromagnet, never flowing through a single turn of the coil.

sorry I don't know why your answers to not correspond but my method is correct
According to snells law
<span>n1 sin theta1 = n2 sin theta2
</span>n1 = 1.333 (water)
<span>n2 = 2.42 (diamond)</span>
it is given that theta =30 degrees so
by putting the values we have
<span>1.333 sin theta = 2.42 sin 30 </span>
<span>sin theta = (2.42/1.333) *0.5 =65.2 degree
</span>so our conclusion is
<span>the ray's angle of incidence θ1 on the diamond</span> = 65.2 degree.
hope this helps
<span>The formula for potential energy is mass * gravity * height. With height given as 20m and weight given as 7.9kg, we can fill in 7.9 * gravity * 20. Gravity is 9.8m/s constant so 7.9 * 9.8 * 20 = potential energy. The result is 1549.45, with the unit of energy being joules. Final answer 1549.45 J</span>
Polar regions do not receive direct sunlight during the winter months due to the tilt in the Earth's<span> axis. Hence, polar regions can get very cold. Antarctica is the </span>coldest place on Earth. <span>The </span>coldest places on Earth<span> tend to be located </span>near the poles<span>. Hope this answers the question.</span>
