Aballoon is 3m in diameter and is filled with 5 kg of n: a. find the specific volume of the gas in the balloon. express it in both m/kg and in m/kmol. answers: about 3 and 80, respectively find the weight of the gas in the balloon, expressed in n. assume g = 9.8 m/s. about 50 b.

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.

continuous conducting path for current, power supply

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
