Answer:

The force then channels down through the walls to the floor. The force of the walls pushing down on the floor is exactly balanced by an equal force when the floor pushes up on the wall. ... The main, structural walls are called load-bearing walls and they're usually built from solid brick or stone.

The 2 forces that act on atoms are the electromagnetic force and the strong nuclear force.
dolphi86 [110]

Electromagnetic forces occur between electrons and protons while nuclear forces occur between neutrons and protons in the nucleus.

Electromagnetic forces are the forces that are responsible for the attraction between electrons and protons. The electrons in shells repel each other.

The existence of electromagnetic forces explain why positively charged protons repel each other in the nucleus and neutrons are needed to buffer this effect.

The electromagnetic force has a short range. The strong nuclear force applies to the nucleus and focuses on the neutron - proton ratio.

An atom is unstable if it has too many protons because their repulsive force will exceed the nuclear force that keeps them together. Nuclear force is stronger for lighter nuclei than heavier ones.

Compare and contrast the alkaline battery and a Zinc carbon battery. put in some other facts about them too. write somewhere aro
Snezhnost [94]
The alkaline batteries, have a higher energy density and the time a battery can remain in storage without losing any of its capacity. Also, there is a specially designed coating inside the batteries that reduces contact resistance for greater reliability. Lastly, the alkaline cells have an extra power formula to maintain power for a longer period of time in high drain devices. Alkaline batteries provide more energy than zinc carbon batteries.

The Zinc carbon batteries, are a reliable source of power for appliances that consume little energy. Some examples are: remote controls for televisions, clocks, and smoke detectors. A reason that you should use the Zinc carbon batteries is for, the low energy consumption. This will lead to being able to use the appliances for a longer time for the same money.

The difference between the batteries is the capacity. Because of composition, an alkaline battery, delivers more energy than a zinc carbon battery.
The only downside is that, both batteries need to be used in different appliances.

Hope this helps! :)
