Answer:
Natural sources include decomposition, ocean release and respiration. Human sources come from activities like cement production, deforestation as well as the burning of fossil fuels like coal, oil and natural gas.
<u>We are given:</u>
Initial Temperature = 90°c
Final Temperature = 120°c
Heat applied(ΔH) = 500 Joules
Specific heat(c) = 0.9 Joules / g°C
Mass of Aluminium(m) = ?
<u>Change in temperature:</u>
ΔT = Final temp. - Inital Temp.
ΔT = 120 - 90
ΔT = 30°c
<u>Calculating the mass:</u>
We know the formula:
ΔH = mcΔT
replacing the values:
500 = m(0.9)(30)
500 = m(27)
m = 500/27
m = 18.52 grams
The answer would be:
D = M/V
D=Density
M= mass
V= volume
<span>The correct answer is B. false or mistaken idea often based on illogical or invalid reasoning and facts. This includes things like generalizing when making claims, or things like the ad hominem fallacy where you try to refute one's argument by attacking the person and no the argument. There are numerous different fallacies and avoiding them is the key to making a sound argument when trying to prove something.</span>
