Your friend decides to generate electrical power by rotating a 100,000 turn coil of wire around an axis in the plane of the coil
MakcuM [25]

Answer:

a) I=35mA

b) P=1.73W

Explanation:

a) The max emf obtained in a rotating coil of N turns is given by:

emf_{max}=NBA\omega

where N is the number of turns in the coil, B is the magnitude of the magnetic field, A is the area and w is the angular velocity of the coil.

By calculating A and replacing in the formula (1G=10^{-4}T) we get:

A=\pi r^2 =\pi(0.23m)^2=0.16m^2

emf_{max}=(100000)(0.3*10^{-4}T)(0.166m^2)(140\frac{rev}{s})=69.72V

Finally, the peak current is given by:

I=\frac{emf}{R}=\frac{69.72V}{1400\Omega}=49.8mA

b)

we have that

I_{rms}=\frac{I}{\sqrt{2}}=\frac{0.0498A}{\sqrt{2}}=0.035A

P_{rms}=I^2{rms}R=(0.035A)^2(1400\Omega)=1.73W

hope this helps!!

Higher temperatures along with moisture climates generally increase the rate of
Bad White [126]

Answer:

Option (D)

Explanation:

Weathering refers to the disintegration of rocks due to the different geological processes that are initiated by agents such as wind, water and ice.

In a region where the temperature is high, and there is sufficient amount of moisture content in the air, there occurs high rate of physical, chemical and biological type of weathering.

  • Physical weathering processes such as freeze-thaw method and exfoliation method commonly occurs in this type of region.
  • Chemical weathering processes such as hydrolysis, oxidation, as well as carbonation method occurs in the region of high temperature, moist climatic condition.
  • Biological weathering also is possible up to some extent as the plants takes up water from the rainfall and also receive enough sunlight for its growth, as a result of which it leads to the breakdown of rocks.

Thus, the correct answer is option (D).
