Why does a van der Graff generator repel a stack of tin foil plates?

Since tin foil is a conductor, it acquires the same charge as the van der Graff generator. Likes repel, thus the plates are repelled.

Why are nuclear plant smoke stacks not straight?
Usually the stack in a nuclear power plant is of smaller diameter as we go up from base to stack top. This is to increase the drift velocity of the exhaust to get out from the stack. It is a matter of fluid mechanics design.
What kind of force will a stack of magazines exert on a table?
The kind of force that a stack of magazines exert on a table is known as gravitational force. This is considered to be a type of potential energy.
What goes up a power plant stack?
Burnt gasses

Why does a van der Graff generator repel a stack of tin foil plates one at a time?
because the "inside" plates have no charge (they are in a Faraday cage made by the top plate and the VDG), but the top plate has the same charge as the VDG so is repelled, the next sheet then becomes the top one and so on. Mr Sparky

Is it proper to stack dirty plates at the table?
Leaving them there very long will allow bacteria to develop. It's okay to leave them for a short time. For a formal dinner, you may not want to stack the dirty plates on the table.

What are the advantages of using square plates?
The advantages of using square plates include having a lip so that sauces don't spill over the edge, they stack better and they look better and more contemporary.
Why does a stack have Last in First out configuration?
If you imagine a stack as a pile of dinner plates then, if you want to remove a plate the only one you can remove is the one at the top of the pile. Similarly if you want to add a dinner plate the only place you can put it is at the top of the pile. Thus using a stack the process of dealing with its contents it is like the pile of dinner plates the one you get to deal with first is the last one you placed in the pile and so on - last in first out!.

Are FIFO and LIFO forms of access used to add and remove nodes from queue?
No. FIFO is a first-in, first-out structure, and this describes how nodes are inserted and extracted from a queue. That is, new nodes are inserted at the back of the queue while existing nodes are extracted from the front of the queue. In other words, nodes are processed on a first-come, first-served basis. However, LIFO is a last-in, first-out structure and this describes how nodes are inserted and extracted from a stack. You can think of a stack as being like a stack of plates such that the top-most plate is always the first to be extracted while new plates are placed on top of existing plates. Stacks are typically used in backtracking algorithms because nodes are extracted in the reverse order they were inserted upon the stack.
What are Disadvantage of stack?
A stack is a LIFO (last-in, first-out) data structure such that only the top-most element is accessible and all new elements are pushed onto the top (analogous to a stack of plates). Stacks are advantageous when implementing a back-tracking algorithm but are ultimately useless for anything else. However, this is not a disadvantage. If you're not implementing a back-tracking algorithm then the problem is not the stack itself it is the fact that you are using the wrong type of container for your algorithm.
What does it mean that the stack is a LIFO structure?
LIFO stands for Last In First Out. It basically means that the most recent piece of data added to a list, will be the first piece that is taken off. It is often compared to a stack of plates. When you have a plate to add to the the stack, you put it on the top, not in the middle or at the bottom of the stack. If you need a plate you usually take it from the top, not the middle or bottom. So the most recent plate on the top is the first that will be taken off when one is needed.
