Sneaky question.
The secondary voltage will be zero.
Secondary voltage is the result of CHANGES in the primary voltage. That means the primary is energized with AC. The transformer in this question is energized with DC, which doesn't change. So there is no secondary voltage, this transformer doesn't work, and what you get out of it is: Smoke !
Answer:
e) 31.6 seconds
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration
Equation of motion




Time taken by the cars to meet 31.6 seconds.
Boiling point and acc motivation
Increasing the temperature causes the particles in the reaction to become kinetically excited, hitting one another in increasing frequency. Increased collision among means faster rate or reaction.
Thermal energy (or thermal kinetic energy) is the total kinetic energy of particles in an object
