Answer:
N₂/N₁ = 45
Explanation:
The relation of the number of turns with the voltage is given by the EMF equation of transformer:
(1)
<em>where V₁: voltage of the primary winding, V₂: voltage of the secondary winding, N₁: number of turns in the primary winding, and N₂: number of turns in the secondary winding </em>
Assuming that the primary winding is connected to the input voltage supply, and using equation (1), we can calculate the ratio of N₂ to N₁:
So, the ratio N₂/N₁ is 45.

Answer : The best pressure is 110 GPa of the lower mantle.
Explanation : We know that the pressure in the lower mantle starts at 24 GPa and reach a 136 GPa at the boundary.
So, the best pressure is 110 GPa because 220 GPa, a 305 GPa and 360 GPa are the higher value of the maximum value 136 GPa of the lower mantle.
