• Contact forces take effect immediately after the force is applied whereas there is a time gap between the application and the effect of non-contact forces.

• Contact forces can be represented by vectors. Non-contact forces can be represented by vector fields.

• There is always a field associated with a non-contact force, but there are no fields associated with a non-contact force.

Nerve cells are also known as neurons. These are the primary building blocks of the nervous system in humans and animals. Its main function is transmitting and receiving electrochemical messages. They help in the transmission of sensory information to the central nervous system and the regulation and control of organs in the body.
A typical neuron consists of a cell body, dendrites, and an axon.
The cell body contains the necessary structures for keeping the neuron functional. That includes the nucleus, mitochondria, and other organelles.
Dendrites are thin structures that arise from the cell body, often extending and have many branches, giving rise to a complex "dendritic tree".
An axon is a special cellular extension that arises from the cell body and travels for a distance, as far as 1 meter in humans or even more in other species.

The Space Shuttle's large External Tank is loaded with more than 500,000 gallons of super-cold liquid oxygen and liquid hydrogen, which are mixed and burned together to form the fuel for the orbiter's three main rocket engines. Liquid hydrogen is used as a fuel in spacecraft. In combination with an oxidizer such as liquid oxygen, liquid hydrogen yields the highest specific impulse, or efficiency in relation to the amount of propellant consumed, of any known rocket propellant.

The yellow colour comes from the soot particles produced by the flame. Yellow or red flames only burn at around 1,000 degrees C. This flame is dangerous as it produces more poisonous carbon monoxide gas. Gas burners burn blue if the ratio of fuel to air is correct. A yellow burner flame is a symptom that the burner is not getting enough air for complete combustion of the gas. To adjust the color of the flames so there is a soft yellow tip at the top of the flames, the gas adjustment should be left alone and the air input reduced by partially closing the air shutter located at the end of the burner.

Cells are always created and destroyed in the human body. About 300 million cells die every minute in our bodies! Since different cells have different jobs in our body, there are about 210 different "types" of cells. The number of cells that an adult male loses per minute is roughly 96 million. Fortunately, in that same minute, about 96 million cells divided, replacing those that died. Just as you shed dead skin cells, dead cells from internal organs pass through and out of the body with waste products.
