What is the output voltage from a step up transformer with 25 turns in the primary coil and 75 turns in the secondary coil if th
Greeley [361]

Answer:

360 V

Explanation:

We can use the transformer equation:

\frac{V_p}{N_p}=\frac{V_s}{N_s}

where

V_p is the primary (input) voltage

N_p is the number of turns in the primary coil

V_s is the secondary (output) voltage

N_s is the number of turns in the secondary coil

In this problem,

V_p = 120 V\\N_p = 25\\N_s = 75

Substituting into the equation, we can find the output voltage:

V_s = N_s \frac{V_p}{N_p}=(75)\frac{120}{25}=360 V

Which trophic level has the least available energy in kilojoules in this food web?
insens350 [35]

The highest trophic level has the least available energy in kilojoules.

Even though the food web is not shown in the question, but we know that energy decreases steadily as it is passed on from one trophic level to the next according to the second law of thermodynamics.

Energy enters into the system from the sun. The primary producers utilize this energy to produce food. As plants are eaten by animals, this energy is transferred along the food web an diminishes at each higher trophic level.

At the highest trophic level, the the least available energy in kilojoules in this food web is found.
