Explanation:
First, determine the amount of vinegar in grams by multiplying the volume by the density. That is,
mass = (355 ml) x (1.01 g/mL) = 358.55 g
Then, multiply the calculated mass above by the decimal equivalent of the given percentage above.
amount of acetic acid = (358.55 g)(0.0602) = 21.58 g

Answer:
Magnetism surrounding the wire draws the needle toward the wire.
Explanation:
Magnetism is a force which is responsible for the attraction and repulsion of objects. Magnetism is also generated around the wire in which current is flowing. This magnetism is stronger when more current flows through the wire. This magnetism is stronger than the magnetism of the poles so when the compass brought near to the electric wire, the needle moves toward the wire.
