Answer:
0.02325 m^3
Explanation:
P1 = 100000Pa , v1 = 0.0279m^3
P2= 120000Pa . V2 = ?
as mass and temperature are constant using ratio method for Boyle'slaw
P2V2= P1V1
or V2= P1V1/P2
V2 = 100000×0.0279/120000
V2= 0.02325 m^3
For Anya:v 1 = 3.3 mph, v 2 = 8.3 mph5 : 2 = 2.5 mi ( half of the distance )
t1= d/v1 = 2.5 mi/ 3.3 mph = 0.7576 ht2 = d/v2 = 2.5 mi/8.3 mph = 0.3 hIn total: 0.7576 + 0.3 = 1.0576 hFor Ilya: 8.3 t / 2 + 3.3 t / 2 = 5 / * 28.3 t + 3.3 t = 1011.6 t = 10t = 10 : 11.6t = 0.86 hHe covers the distance for 0.86 h.His average speed:v = 5/0.86 = 5.81 mph.
Answer:
There isn't enough information to solve. Is this related to a graph? The initial and final velocities are needed. The expression for solving is noted under Explanation.
Explanation:
Given final velocity, initial velocity and displacement, one can solve for the acceleration using:
a=v2−u22s,
where v is final velocity (m/sec), u is initial velocity (m/sec) and s it the distance travelled (in m).
Well, that's not actually "diffraction".
The fuzzy edge of the moon, and the added glow that's sometimes seen
around it, are all effects caused by the light passing through air before it
reaches you.
This gives you some idea of why astronomers go to such effort and
expense to get their telescopes above as much of the atmosphere as
possible ... placing all serious observatories on mountaintops, and even
putting telescopes in orbit. It's all because the air does such a job on the
light that's trying to shine through it. We have to make do with whatever's
left over after that.
