Final answer:

The energy transferred is 157.5 Joules.


Step-by-step explanation:

To calculate the amount of energy transferred, we can use the equation:

Energy = Power x Time

Given that the power is 2.5 W and the time is 63 s, we can substitute these values into the equation:

Energy = 2.5 W x 63 s

Calculating the product, the energy transferred is 157.5 Joules.
