Answer:
Weight of air per unit area is pressure due to atmosphere. So here correct answer is Weight
Explanation:
As we know that air pressure is given by
now we know that force here due to air is due to the weight of the air
so here in order to calculate the weight we will have
here we know that
Ah = volume of air above the point where pressure is to be calculated
now from above formula we have
so here we can say that pressure is due to weight of air
Copper plating is the process of plating a layer of copper electrolytically on the surface of an item. ... As the copper ions dissolve into the water, they form a coordination complex with salts already present. The copper then physically flows to the item, where it is reduced to the metallic state by gaining electrons.

When you touch a doorknob, all the charge wants to leave you and go to the doorknob. You see a spark and get a shock as the electrons leave you. Lightning is the result of static electricity.
Answer:
Precision
Explanation:
You can be very precise but inaccurate, as described . You can also be accurate but imprecise. For example, if on average, your measurements for a given substance are close to the known value, but the measurements are far from each other, then you have accuracy without precision. Precision is independent of accuracy. You can be very precise but inaccurate, as described above. You can also be accurate but imprecise. For example, if on average, your measurements for a given substance are close to the known value, but the measurements are far from each other, then you have accuracy without precision. Precision refers to the closeness of two or more measurements to each other. Using the example above, if you weigh a given substance five times, and get 3.2 kg each time, then your measurement is very precise.
