To find the net charge you take the number of protons and subtract the number of electrons, and the answer will be your charge.
This atom has 11 electrons AND 11 protons
11 - 11 = 0 net charge
I think the answer is c. the more characteristics they have in common. Sorry if wrong.
The fraction of Oil will be 0.8and block will be 0.95
What is density?
Density is the ratio of Mass of a compound upon Volume of that compound. It's SI unit can be g/cm³, kg/m³.
As we know the Density of water is 997Kg/m³≈1000Kg /m³.
1) Fraction of Oil is
800/1000=0.8
2) Fraction of Block is
950/1000= 0.95.

Answer:
a
Increasing
b
Explanation:
From the question we are told that
The initial speed is
The time taken is
Generally given that the stone is moving downward the acceleration is equivalent to the generally value of acceleration due to gravity and it would be increasing as the stone approaches the ground(toward the center of the earth )
Thus the acceleration is
Generally from the equation of motion we have that
