Answer:
0.1 L
Explanation:
From the question given above, we obtained the following data:
Initial volume (V₁) = 0.05 L
Initial Pressure (P₁) = 207 KPa
Final pressure (P₂) = 101 KPa
Final volume (V₂) =?
We can obtain the new volume (i.e the final volume) of the gas by using the Boyle's law equation as illustrated below:
P₁V₁ = P₂V₂
207 × 0.05 = 101 × V₂
10.35 = 101 × V₂
Divide both side by 101
V₂ = 10.35 / 101
V₂ = 0.1 L
Thus, the new volume of the gas is 0.1 L
Answer:
Explanation:
The diffraction pattern is given as
Sinθ = mλ/ω
Where m=1,2,3,4....
Now, when m=1
Sinθ = λ/ω
Then,
ω = λ/Sinθ
The width of the central bright fringe is given as
y=2Ltanθ. From trigonometric
Then,
θ=arctan(y/2L)
Given that,
y=0.052m
L=0.55m
θ=arctan(0.052/2×0.55)
θ=arctan(0.0473)
θ=2.71°
Substituting this into
ω = λ/Sinθ
Since λ=544nm=544×10^-9m
Then,
ω = 544×10^-9/Si.2.71
ω = 1.15×10^-5m.
If v=22m/s after0.02s then acceleration was
22/0.02=1100m/s^2
Now, F=ma=(0.5)(1100)=550N
