Explanation:
In thermodynamics, an adiabatic process is a type of thermodynamic process which occurs without transferring heat or mass between the system and its surroundings.Unlike an isothermal process, an adiabatic process transfers energy to the surroundings only as work. It also conceptually supports the theory used to explain the first law of thermodynamics and is therefore a key thermodynamic concept.
Answer:
today's species evolved from those of the past.
Explanation:
By comparing fossils of a specie from long ago to those of today, we can conclude that today's species evolved from those of the past.
- Fossils are the preserved remains of ancient life forms found within sedimentary bed layers.
- These fossils helps scientists to understand ancient life forms.
- According to the discovery of Charles Darwin, organisms have evolved and are still evolving.
- Understanding past life forms gives a way to characterize present day species better.
Answer:
0 kgm/s
Explanation:
The momentum is the product of mass(m) and velocity(v).
Initially the velocity of truck is 0 m/s so the product of mass and velocity becomes 0.
It does not matter what is the weight of truck, because the velocity will make the product of m*v = 0
It does not matter what is the momentum of car.
