False, it would actually increase. Plants absorb carbon dioxide for photosynthesis
Answer:
-20 kg.m/s
Explanation:
We have an object moving at 5 m/s with mass 5 kg. The initial momentum is:
pi = m × vi
pi = 5 kg × 5 m/s = 25 kg.m/s
It undergoes a quick collision with some other object and now moves at 1 m/s. The final momentum is:
pf = m × vf
pf = 5 kg × 1 m/s = 5 kg.m/s
The change in the object's momentum is:
Δp = pf - pi
Δp = 5 kg.m/s - 25 kg.m/s = -20 kg.m/s
Answer:
The charge on the wool after rubbing is - 10 C
Explanation:
Every uncharged body is electrically neutral, if the plastic rod acquires 10 Coulombs of charge after been rubbed with wool, then the wool will be left with an equal but opposite charge. This shows that the initial charge on the wool is 10 protons and 10 electrons and when the plastic acquires 10 C (10 protons), the wool will be left with excess 10 electrons.
Therefore, the charge on the wool after rubbing is - 10 C (negative 10 Coulombs).
