Answer:
2.36 x 10^6 Hz
Explanation:
We know ;,
Iamp = 1.8mA
L = 0.45mH
VL = 12V
VL = IwL
VL = I x 2π x f x L
f = VL / (I x 2π x L)
f = 12 V/ (1.8mA x 2π x 0.45mH)
f = 12/(1.8x10^-3 x 2π x 0.45 x 10^-3)
f = 2.36 x 10^6 Hz

The answer is; C
In particular points in the earth’s surface, underground water is naturally heated to steam that can be harness for geothermal energy. The steam that ejects from the ground with high kinetic energy can be used to turn turbines that generate electricity. The underground water is usually heated by the hot rocks beneath that are subjected to the immense heat of magma or the enormous pressure of overlying crust.
Explanation:
<em><u>Principle of Floatation</u></em>
Principle of Floatation states that weight of floating body is equal to weight of water displaced by it
