How high are fireworks when they explode?
Depends entirely on the firework. A bottle rocket may travel 100 ft, but large firworks fired from motars may go as high as 3,000 ft. It will depend on the weight of the shell, the amount of the propelling charge, and the time of the delay fuse.
Why does the gun recoils and puch the person back when fired?
When a gun is fired a bullet (or cartridge) with a small mass but a very high velocity is ejected. The recoil of the gun is a reaction to this force and is sufficient to push back the person who fired the weapon.
Does a fired gun smell of fireworks?
Yes.
What condition is neuron in when the outside of the neuron has a net positive charge and the inside has net negative charge?
This is called the resting potential (inactive state) of the neuron. However, when a neurotransmitter binds to receptors, electrical stimulus is applied, etc. to induce an opening of ion channels in the membrane of the neuron, positive ions rush into the neuron from the outside to the inside, and result in a sharp increase of the positive charge density (due to more positive ions) inside the neuron. Beyond a certain threshold, this can induce the creation of an action potential, causing the neuron to fire. After the action potential is created, and the neuron fires, there is a short refractory period where the neuron cannot be fired again due to stimuli, when positive ions are pumped back out of the neuron, negative ions are brought into the neuron, and then the ion channels close, leaving the neuron in a polarized state, and returning it to a resting potential.
How does a neuron indicate the strength of a stimulus?
A neuron conveys information about the strength of stimuli by varying the rate in which the stimulus is fired.
Do axon and dendrite touch?
No they do not. Information (neurotransmitters) is electrically fired over to the next neuron.
What is the order of firing a neuron?

How does neuronal firing cause muscle contraction?
When a neuron in a muscle is fired, or triggered, it sends a message to the brain telling the muscle to contract.
