El helio es más ligero que el aire y a diferencia del hidrógeno no es inflamable, siendo además su poder ascensional un 8 % menor que el de este, por lo que se emplea como gas de relleno en globos y zepelines publicitarios, de investigación atmosférica e incluso para realizar reconocimientos militares.espero ke esto ayude!
I think it would be the scientific method.
The average current is 0.10 A.
<h3>Current </h3>
Charge moving through a location on a circuit at a constant rate is called current. When numerous coulombs of charge pass over a wire's cross section in a circuit, it produces a large current. It is not necessary for a wire to be moving at a fast speed in order to have a high current if the charge carriers are tightly packed into the wire. To put it another way, many charge carriers traveling through the cross section is sufficient; they do not need to travel a great distance in a single instant. The amount of charges that flow through a cross section of wire on a circuit, as opposed to how far they travel in a second, is what determines current.
A charge of 12 c passes through an electroplating apparatus in 2. 0 min. what is the average current?

Answer:
30 hours
15 hours.
Explanation:
Let the Kelly used sprinkler for t hours and Gracia used the sprinkler for the rest ie (45 - t) hours .
Water output by Kelly = (35 x t) L
Water output by Gracia = 20 ( 45 - t ) L
Total output = 35t + 20(45 - t)
So, 35 t + 20 (45 - t ) = 1350
35 t + 900 - 20 t = 1350
15 t = 450
t = 30 hours
So Kelly used sprinkler for 30 hours and Gracia used it for 45 - 30 = 15 hours.
Answer:
W = -1.97KJ, Q = 1.97KJ, Delta U = 0
Delta U = -1.03KJ, Q = -1.03KJ, Delta H = -1.72KJ
Explanation:
The deatiled step by step calculation using the ideal gas equation (Pv =nRT), The first law of thermodynamics ( dQ =dW + dU) as applied is as shown in the attached file.
