If 500mL glass beaker is filled to the brim with ethyl alcohol at a temperature of 5⁰C, how much less water would overflow under the same condition?​

The change in volume or amount of overflow is 1.79 mL . Hence, 7.56 mL of lesser water would overflow under the same condition.

object 2 because all the other ones are wrong

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
