Answer:
30.0625 W
Explanation:
325 g/h x (1h x 1kg)/(3600s x 1000g) x 3,33 x 10^5 J/Kg = 30.0625 J/Kg = 30.0625 W
Answer:
Question doesn't make sense
Explanation :
We know that the slope of velocity -time graph gives the acceleration. Acceleration of an object is defined as the rate of change of velocity i.e.
Suppose a driver suddenly applies brakes. In this case the initial velocity of his or her vehicle is more and the final velocity is less.
So, the acceleration is negative in this case i.e. the object is decelerating.
A negative slope on the velocity versus time graph indicates that an object is not accelerating. This statement is false as the object is decelerating.
Answer:
Part a)
ZERO
Part b)
N = 10 turns
Explanation:
Part a)
As we know that transformer is used to change the input voltage into required output voltage
Here this input and output is considered only when it will change with time as the whole concept is based upon Faraday's law where we need to change the flux with time.
So if we have input Source is DC source then output voltage will be zero as there is no flux change
Part b)
As we know by the principle of transformer
so total number of turns in secondary coil must be 10
