A student spends 4.5 hours studying for a test. How much time is this equivalent to in seconds? Select one:
a. 2,700 seconds
b. 16,200 seconds
c. 270 seconds
d. 6,480 seconds

B. 16,200

Explanation:

1) Reduce.

4.5 hours can be translated to minutes. We know there are 60 minutes in an hour.

4.5 * 60 = 270 minutes

2) Reduce further

270 minutes can then be translated to seconds using the same equation

270 * 60 = 16,200

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.
