Answer:
In studying the origin of the universe, one of the primary unanswered questions is <u>what came before the big bang.</u>
Explanation:
The big bang theory can be described as a theory which scientists have proposed to explain how the universe came into existence. This theory predicts how the extremely hot temperatures and dense atmosphere might have given rise to the stars and the galaxies.
Scientists have no idea what happened before the big bang theory. Some scientists predict that there might be another universe which collapsed before the big bang theory. While other scientists claim that there was nothing before the big bang.
Answer:
3.94 atm
Explanation:
Using the general gas law equation as follows;
PV = nRT
Where;
P = pressure (atm)
V = volume (L)
n = number of moles (mol)
R = gas law constant (0.0821 Latm/molK)
T = temperature (K)
According to the information provided in this question;
P = ?
V = 50 L
T = 300K
n = 8 mol
Using PV = nRT
P = nRT/V
P = (8 × 0.0821 × 300) ÷ 50
P = 197.04 ÷ 50
P = 3.94 atm
I'd also say that the morphology presented in this picture is filamentous.
The reason for my believing this is that filamentous morphology concerns long visible chains, threads, or filaments, which you can see in the image.
Drive less, accelerate slowly, drive until your tank is empty, avoid excessive idling, eliminate wind resistance.
