Which statement is true about energy changes? A.
Energy cannot be created or destroyed.
B.
Energy can be created but not destroyed.
C.
Energy can be destroyed but not created.
D.
Energy can be created and destroyed.

Using the law of physics, or the conservation of energy, your answer is:

A. Energy cannot be created or destroyed.

8

explanation:

each principal energy level above the first contains one s orbital and three p orbitals. a set of three p orbitals, called the p sublevel, can hold a maximum of six electrons. therefore, the second level can contain a maximum of eight electrons - that is, two in the s orbital and 6 in the three p orbitals.

mark brainliest and have a great day!

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
