good luck with the song lyrics, you got this! :)
Answer: All the circuits have energy source, wires and device that needs electrical energy in common.
Explanation: Electric circuit is a path through which electrons flow from higher potential to lower potential.
A wire is required to connect Energy source and a device that needs electrical energy to run. On the other hand, voltmeter and ammeter are the devices which are used to measure voltage and current respectively and not necessarily used in all the circuits.
Hence, the common components in an electric circuit are energy source, wires and device that needs electrical energy in common.
Answer:
After 1.95x10⁴ s, total pressure is 0.34 atm
Explanation:
t(s) 0 1000 3000 7000
PTotal (atm) 0.15 0.16 0.18 0.20
These are the data of the experiment, so let's make a linear regression
X | Y
0 | 0.15
1x10³ | 0.16
3x10³ | 0.18
7x10³ | 0.20
You can do this by the calculator, but let's do it manually.
Y = mx + b
m = (Y₂ - Y₁) / (X₂ - X₁)
m = 0.18 - 0.16 / 3x10³ - 1x10³
m = 0.02 / 2x10³ = 1x10⁻⁵
b = 0.15 (y-intercept, where x is 09
Y = 1x10⁻⁵ X + 0.15
Notice that in the statement, after 7000 s, pressure is 0.22 atm
1x10⁻⁵ . 1.95x10⁴ + 0.15 = 0.34atm
If you are talking about the element the element is phosphorus
