The latent heat of vaporization for water is
2257 KJ per Kg . I'm pretty sure that's exactly
the same as 2257 joules per gram. So ...
When 1 gm of STEAM at 100 C condenses to
1 gm of liquid water at 100 C, it releases
2257 joules of heat energy to its environment.
Answer:
α = 1.32 rad/s²
Explanation:
given,
diameter of the bicycle = 0.8 m
radius of the bicycle = 0.4 m
initial speed of the bicyclist,u = 0 m/s
final speed of the bicyclist,v = 22 Km/h = 22 x 0.278
= 6.12 m/s
time,t = 11.6 s
acceleration =
=
=0.53 m/s²
we know,
a = α r
α = 1.32 rad/s²
the angular acceleration of the wheels is equal to α = 1.32 rad/s²
Answer: D. An action-reaction force pair
Explanation: When you sit in your chair, your body exerts a downward force on the chair and the chair exerts an upward force on your body. There are two forces resulting from this interaction - a force on the chair and a force on your body. Another example would be a person pushing against a wall (action force), and the wall exerts an equal and opposite force against the person.
Answer:
Well,
Explanation:
In a wave, energy is transported without the transport of water. Basically, a wave can be described as a disturbance that travels through a medium, transporting energy from one location to another location without transporting matter.
