1 horsepower is equal to 746 W, so the power of the engine is
The power is also defined as the energy E per unit of time t:
Where the energy corresponds to the work done by the engine, which is
. Re-arranging the formula, we can calculate the time t needed to do this amount of work:
The power is also defined as the energy E per unit of time t:
Where the energy corresponds to the work done by the engine, which is
Answer:
8.4 V
Explanation:
induced emf, e1 = 5.8 V
Magnetic field, B1 = 0.38 T
magnetic field, B2 = 0.55 T
induced emf, e2 = ?
As we know that the induced emf is directly proportional to the magnetic field strength.
When the other parameters remains constant then
e2 = 8.4 V
Thus, the induced emf is 8.4 V.
Answer:
The equivalent capacitance will be
Explanation:
We have given two capacitance
They are connected in parallel
So equivalent capacitance
This equivalent capacitance is now connected in series with
In series combination of capacitors the equivalent capacitance is given by
So the equivalent capacitance will be
