I think the correct answer from the choices listed above is option A. When heat is removed, a gad become a liquid because the particles in a liquid have less kinetic energy than the particles in gas. As the heat is removed, the particles will experience in decrease of their kinetic energies.
Answer:
because in the roller coaster you have a big seat belt soo you won't fall
Answer:
(C) T
The tension T at equilibrium will be equal to the Buoyant force.
The Buoyant force is given by:
Fb = density x acceleration due to gravity x volume displaced
The change in height doesn't affect the Buoyant force and hence the tension.

Answer:
2.5m/s
Explanation:
Kinetic energy = 1/2 mv²
Mass = m= 8000kg
Velocity(speed) = v =
K. E = 24000J
K. E = 1/2 x 8000 x v²
24000 = 4000 x v²
Divide both sides by 4000
V²= 24000/4000
V² = 6
Find square root of both sides
V = √6
V = 2.5 m/s
The S. I unit of energy is joules with symbol J

We know, Frequency = speed / wavelength
f = 341 / 0.8
f = 426.25 Hz
In short, Your Answer would be 426.25 Hz
Hope this helps!
