Answer:
See the explanation below.
Explanation:
Indeed this is a serial circuit, in order to calculate the different questions, we must calculate the current of the circuit. The total resistance of the circuit can be calculated by means of an algebraic summation.
Then using ohm's law,we can calculate the current.
Rt = 2 + 4 + 6 = 12 [ohm]
The current
I = V / Rt
I = 12 / 12
I = 1 [amp]
Therefore the voltage in each resistance will be:
V1 = 2 * 1 = 2 [V]
V2 = 4 * 1 = 4 [V]
V3 = 6 * 1 = 6 [V]
The total voltage will be:
V = V1 + V2 + V3 = 12 [V]
The power can be calculated by multiplying the voltage by the total current.
P = V * I
P = 12 * 1
P = 12 [W]
I think u would add them all up and then write down your answers
Answer: 71.72 days
Explanation:
This problem can be solved using the <u>Radioactive Half Life Formula: </u>
(1)
Where:
is the final amount of Iodine-131
is the initial amount of Iodine-131
is the time elapsed
is the half life of Iodine-131
Knowing this, let's substitute the values and find from (1):
(2)
(3)
Applying natural logarithm in both sides:
(4)
(5)
Finding :
Answer:
C: As a consequence of growing, organisms cause a greater increase in entropy in their environment than the decrease in entropy associated with their growth.
Explanation:
Particularly, whole organisms on the earth obtain the energy from sunlight, and the sun is undertake an vast increase in entropy that simply compensates for the reducing entropy of living things on this small planet.
