Answer:
A) the liquid particals move slower
Explanation:
vapor has a higher temp and have more energy than liquid so it's not c or d. and liquid has a lower boiling point than vapor
I need a pic so I can give you an answer
Acceleration = (change in speed) / (time for the change)
Acceleration = (220 m/s) / (20 sec)
<em>Acceleration = 11 m/s²</em>
Answer:
6.4m/s
Explanation:
The total mechanical energy of the man is 1780J.
This mechanical energy is the energy due to the motion of the body and it is a form of kinetic energy.
Also, mass = 87kg
Kinetic energy = m v²
m is the mass
v is the velocity
1780 = x 87 x v²
v² = 40.9
v = 6.4m/s
