Increasing the pressure of gas is like exactly the same as increasing its concentration. If you have a given mass of gas, the way you increase its pressure is to squeeze it into a smaller volume.
Hope this helps!
Answer:
ω = 10.75 rad/s
Explanation:
The stone leaves the circular path with a horizontal speed
v₀ = vt = R*ω
So
ω = v₀ / R
we are given that R = x / 25.7 so ω = 25.7*v₀ / x
Kinematics gives x = v₀*t
With this substitution for x the expression for ω becomes ω = 25.7 / t
Kinematics also gives for the vertical displacement y that
y = v₀y*t + 0.5*ay*t²
we know that v₀y = 0 m/s
since the stone is launched horizontally, so that
y = 0.5*ay*t² ⇒ t = √(2*y / ay)
Using this result for t in the expression for ω and assuming that upward is positive, we get
ω = 25.7 / √(2*y / ay)
⇒ ω = 25.7 / √(2*(-28) / (-9.8))
⇒ ω = 10.75 rad/s
I believe the correct answer from the choices listed above is the second option. The statement that would best explain the sequence of events would be that the <span> victim shot himself in the mouth. Hope this answers the question. Have a nice day.</span>
Answer:
9.6 km/h
Explanation:
20 minutes=1/3 minute.
The speed of the bicycle: 3.2:1/3=9.6 km/h.
Answer: 9.6 km/h
<span>Alice and Tom will reach the surface of the lake at the same time.
In this problem. Both Alice and Tom have 2 components to their velocities. A horizontal component and an increasing vertical component due to gravity. They start out with different horizontal components, but that component does not in any way contribute to their vertical velocities. Since they both started out at the same height and the same vertical velocities, they will reach the surface of the lake at the same time.</span>
