Answer:
Explained
Explanation:
A model is practical representation of reality with help of various tools called model. It is more purposeful, appealing and provide greater understanding of the specific phenomenon called modeling.
Theory on the other hand are set of written statement which is more generalized and aimed to explain the phenomenon. Theory is developed through the process of abstraction, experimentation, and deduction.
A model is often is used to describe an application of a theory for a specific case.
The turn and voltage ratio of a transformer can be simply expressed by the equation:
Ns/Np = Vs/Vp; where N is the number of turns and V is the voltage.
Plugging in the given values, we have:
25 turns / 100 turns = Vs / 40 volts
Vs = 40 volts (25 turns/100 turns)
Vs = 10 volts

<u>Answer:</u>
<em>Instantaneous velocity is equal to speed of the object at that particular instant.</em>
<u>Explanation:</u>
Instantaneous velocity is the velocity of the object at that particular instant. It is also equal to speed of the object at that instant. It can be calculated by drawing a tangent to the position-time graph at that point and finding the tangent’s slope.
The first option ‘The ratio of change in position to the time interval during that change’ gives the average velocity of an object and not speed. Similarly the second option ‘the absolute value of the slope of position time graph’ gives the average speed.
