Answer:
8 electrons
Explanation:
Now you can figure out how many electrons, protons and neutrons Oxygen has: Atomic number (which is always the smaller of the two numbers) is 8. Hence 8 protons. Because the atom is neutral, there are also 8 electrons.
I'm pretty sure it's true. We glow with "Bioluminescence".
Answer:
1.93 x 10∧3 N

The picture attached shows the calculation
Answer:
1.98 × 10⁻³³m
Explanation:
It is given that,
Mass of the bullet, m = 27 g = 0.027 kg
Velocity of bullet, v = 800 m/s
The uncertainty in momentum is 0.20%. The momentum of the bullet is given by :

Uncertainty in momentum is,

We need to find the uncertainty in position. It can be calculated using Heisenberg uncertainty principal as :
