Answer:
Non of the option applies
Explanation:
Gases may be assumed to obey the ideal gas law, which states that, for pressure P, volume V, number of moles n, and temperature T,
PV = nRT.
where R is the gas constant, and n is the number of mole of gas
If the temperature is held constant, we obtain a simplified version called Boyle's Law, and if the pressure is held constant, we obtain Charles' Law.
Boyle's law:
Boyle's law states that the volume of a given mass of gas is inversely proportional to is pressure, provided that the temperature remains constant.
Mathematically,
P ∝ I/V
∴ PV ∝ 1
From the above mathematical expression, it shows that PV is a constant and does not change with pressure or volume.
∴ non of the options applies
Answer:
If you increase the mass at a given force the rate of acceleration slows. Therefore, mass is inversely proportional to acceleration. ... Force is directly proportional to acceleration (force ~ acceleration) As force increases acceleration increases.
Answer: Option (a) is the correct answer.
Explanation:
A chemical formula which represents proportions between the elements present in a compound is known as empirical formula.
When chemical or molecular formula is able to be reduced to smaller whole-number ratio of the elements then both molecular and empirical formulas are considered to be the same.
Relation between molecular formula and empirical formula is as follows.
Molecular formula = n × Empirical formula
where, n is an integer.
Chemical formula of acetic acid is 
.
Chemical formula of formaldehyde is 
. It is the smaller whole-number ratio of molecular formula of acetic acid.
Chemical formula of Benzaldehyde is 
.
Chemical formula of glucose is 
.
Thus, we can conclude that formaldehyde molecules has/have the same empirical formula as acetic acid (
).
She ran at either 5m/s
Or 11.185 miles/hr
Explanation:
Aight well if she did 100m in 20s then that’s 5m/s which would also be 11.185M/h
m = meters
M = miles
Hope this helps!
