Answer:
554.265 N
Explanation:
Without moving it means it is static. Since we know that normal friction is given by N=mg where m is the mass and g is acceleration due to gravity.
The static friction will then be given by multiplying the normal reaction by the coefficient of static friction. Taking g as 9.81, m as 113 kg and 0.5 for coefficient of static friction then
Fs= 0.5*113*9.81=554.265 N
Answer: plasma
Plasma is produced by ionized gas. Movement of charged particles between energy levels produces plasma.
Examples of partially ionized gas are neon signs and lightning flashes.

Answer:
Explanation:
Oxygen has an atomic number of 8,
Then, it has eight electrons revolving round its nucleus.
And since it a neutral atoms.
Number of neutron ≈ number of electron
Number of proton = Number of electron.
Then, the number of proton is 8
So, we can find it mass number of molecular weight
Molecular weight = number of proton + number of neutron
Molecular weight = 8 + 8
Molecular weight = 16g/mol
So, the correct answer is D
An atom of oxygen has 8 protons.
