Answer:
A) If you look at the vertical rows you can tell how many electrons there are on the outer shell eg. Group 7 (eg. nitrogen) has 7 electrons on its outer shell
B) They are in the same group
C) Helium,Argon and Organessom are all Nobel gasses
Answer:
12 kg
Explanation:
q = 52,800 J
c = 880 J/(kg * K) Pretty sure you missed the kg here
ΔT = 5 °C = 5 K (reminder that this only applies to ΔT and not T)
q = mcΔT ⇒ m = q/(cΔT) = 52,800 J / (880 J/(kg * K) * 5 K) = 12 kg
Answer:
I = 20 A
Explanation:
The question says that, "A load of 6,000 C is conducted through a cross section in 5 minutes. Determining-if a current is not correct, we will find the value of?"
We have,
Charge, q = 6,000 C
Time, t = 5 minutes = 300 s
We need to find the current. We know that, the charge flowing per unit time is equal to current. So,

So, the current flowing through the circuit is 20 A.
