A and c should be the answer
Answer:
The magnitude of their velocities will be the same but their direction will be reversed.
Answer: iron, nickel, and cobalt.
Explanation:
- initial velocity=u=0
- Acceleration=a=6.4m/s
- Time=t=9s
Final velocity be v
According to first equation of kinematics
- v=u+at
- v=0+6.4(6)
- v=57.6m/s
Endless movement between hot and cold will eventually mean the end of the universe. This law is about inefficiency, degeneration and decay. <u>The second law can be expressed in several ways, the simplest being that heat will naturally flow from a hotter to a colder body. At its heart is a property of thermodynamic systems called entropy.</u> Entropy basically means an increase in randomness. Hope this helps mate.
