The purpose of the tension protractor apparatus is to? (could be more than one answer) A) demonstrate the use of pulleys with multiple forces.

B) visualize equilibrium on an object under multiple forces.

C) visualize forces by different length of string.

D) demonstrate the vector nature of forces.

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete

resonant frequency

explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right

i think the answer is a and b

i wish you luck
