Answer:
Explanation:
To solve this problem we will use the Ideal Gas Law, which forms the following formula
Where
= Pressure of Gas
= Volume of Gas
= Moles of Gas
= Constant = 0.0821 atm L/mol K
= Temperature of Gas
There are two states to consider
State 1 is given
= 0.741 atm
= 112 mL
= unknown
= 0.0821 atm L/mol K
= 300K
State 2 is based on Standard Room Temperature Pressure (STP) which are fixed values
= 1 atm
= unknown
= unknown
= 0.0821 atm L/mol K
= 273.15K
Since this is the same mass of gas it can be reasoned that the moles of gas are the same. We rearrange the Gas Law Formula to the following
We input the values and equate the formulas for both states by substituting the value of n
Answer
Answer:
Explanation:
pressure is the force applied perpendicular to the surface area of an object per unit area.
for the question,
Force (F) = 5000N
Ok a full paragraph is at least 5 sentences
1. "A sonic boom is a phenomenon that happens when a supersonic plane travels at speeds greater then the speed of sound."
2. "The way this happens is that as the plane is traveling at supersonic speeds ( speeds greater than that of sound) this means it's going faster than its own sound."
3. "As a result, a pressure wave is produced in the shape of a cone which has its vertex at the nose of the plane and its base behind the plane."
4. "The angle opening on the cone depends on the speed the plane is traveling at. All of the sound pressure is contained in this cone."
5. "Imagine the plane is traveling towards you. As it reaches near you, you can see it but you cannot hear anything. As your ears touch the edge of the cone, you hear the very loud sonic boom. You hear the sonic boom as your ears reach the cone ; not when the plane breaks the sound barrier."
Hope this helps. Okay its more than 5 but maybe thats better :D
The center of gravity of the homogeneous semicircular rod bent is 2R/π .
We need to know about center of mass to solve this problem. Center of mass can be determined as
Xm = ∫x . dm / ∫dm
Assume that
dm = λ .dl
with radius R and angle θ we get
dm = λ . dl
dm = λ . R dθ
Hence the (∫x . dm) from 0 to π is
∫x . dm = ∫ λ . R dθ
∫x . dm = ∫ R.sinθ. λ. R dθ
∫x . dm = λ. R² ∫sinθ dθ
∫x . dm = λ. R² [-cosθ]
with limit of integral from 0 to π we get [-cosθ]
∫x . dm = λ. R² [- (-1) - (-1)]
∫x . dm = 2λ . R² = 2 . (0.5) . R² = R²
The (∫dm) from 0 to π is
∫dm = ∫λ . R dθ
∫dm = λ . R ∫dθ
∫dm = λ . R ∫dθ
∫dm = λ . R [θ]
with limit of integral from 0 to π we get [θ]
∫dm = λ . R . π = 0.5 Rπ
Hence, the center of mass is
Xm = ∫x . dm / ∫dm
Xm = R² / (0.5 Rπ)
Xm = 2R/π
where R is radius of the semicircular rod bent.
