Answer:
It represents the amount of speed per time or (x) for speed (y) for time so the slope would be like y/x
Ionic compounds typically have high melting and boiling points, and are hard and brittle. when melted or dissolved they become highly conductive, because the ions are mobilized.
Smoother because it will increase energy and when the energy increases it’ll create heat also . Example: A car racing on a smooth road it’ll go faster than a Car speeding on a bumpy and rough road , Hope that helps .
Answer:
The rms voltage (in V) measured across the secondary coil is 459.62 V
Explanation:
Given;
number of turns in the primary coil, Np = 375 turns
number of turns in the secondary coil, Ns = 1875 turns
peak voltage across the primary coil, Ep = 130 V
peak voltage across the secondary coil, Es = ?

The rms voltage (in V) measured across the secondary coil is calculated as;

Therefore, the rms voltage (in V) measured across the secondary coil is 459.62 V
The question in choice-C is the correct answer to your question.
