No waves because Q19 waves would going at the surface at regions
Answer:
Explanation:
Flux through the coil = nBA , n is no of turns , B is magnetic flux and A a is area of the coli
= 200 x 5.6 x 10⁻⁵ x 11.8 x 10⁻⁴
= 13216 x 10⁻⁹ weber .
b ) When the coil becomes parallel to magnetic field , flux through it will become zero.
c ) e m f induced = change in flux / time
= 13216 x 10⁻⁹ / 4.9 x 10⁻²
= 2697.14 x 10⁻⁷ V
= 269.7 x10⁻⁶
269.7 μV.
The physical description would be soft due to the lava cooling the rock.
Answer:
Look to the explanation
Explanation:
<u><em>Work done</em></u> is is the energy transferred to or from an object by means
of a force acting on the object.
Work is positive if energy transferred to the object, and work is
negative if energy transferred from the object.
<em>Work = Force in the direction motion of object × its displacement</em>

The SI unit of the work is joule (J)
<u><em>Power</em></u> is the rate of work
<em>Power = work done ÷ time taken</em>
Power = 
Displacement (s) ÷ time (t) = velocity (v)
<em>Power = Force × velocity</em>

The SI unit of the power is watt (w)
