Based on the construction, the length of the bridge deck is given by r = √(x² + y²) units.
<h3>What is a deck?</h3>
A deck is also referred to as the roadway and it can be defined as the functional area which is designed and developed to allow automobile vehicles and pedestrians to cross highways, valleys, and water bodies.
In order to determine the length of the bridge deck, we would apply Pythagorean's theorem as follows:
r² = x² + y²
<u>Where:</u>
- r is the length of the bridge deck.
- a is the adjacent side (horizontal distance).
- b is the opposite side (rise of the bridge).
Making r the subject of formula, we have:
r = √(x² + y²)

The gas with a higher pressure is <u>Helium </u>
<h3 /><h3>Calculating the pressure exerted by the gases</h3>
Given that temperature and volume is held constant the pressure of a given gas can be calculated as : P = n because for a constant volume and temperature the pressure of a given gas is directly proportional to the number of moles of contained in the gas.
<u>Pressure of </u><u>Helium </u>
P = n
where n ( number of moles ) = mass of helium / molar mass
= 52 / 4 = 13 moles
<u>Pressure of</u><u> Ammonia </u>
P = n
where n ( number of moles ) = mass / molar mass of ammonia
= 73 / 17.03
= 4.29 moles
From the calculations above the gas with a higher pressure is Helium.
