What is the nervous system?

Nervous system is a s system in the body that helps in the coordination between all the body parts and the brain which is the control center.

How is the nervous system classified?

The nervous system is classified into central nervous system and peripheral nervous system.

What comprises of the central nervous system?

The central nervous system is made up the brain and the spinal cord.

What comprises of the peripheral nervous system?

The peripheral nervous system is comprised of all the parts of the nervous system outside the brain and the spinal cord.
It includes the sensory neurons and the motor neurons.
Motor neurons transmits impulses from the brain to the effector cells such as muscles and glands.
Sensory neurons, on the other hand, transmit nerve impulses from the sensory organs to the central nervous system.

Express the following numbers in scientific notation:

uranmaximum [27]

Answer :

(a) The number in scientific notation is, $6.0200\times 10^4L$

(b) The number in scientific notation is, $4.520\times 10^3J$

(c) The number in scientific notation is, $6.00\times 10^{-3}mg$

(d) The number in scientific notation is, $1.023\times 10^{-2}km$

(e) The number in scientific notation is, $8.070\times 10^1mL$

Explanation :

Scientific notation : It is the representation of expressing the numbers that are too big or too small and are represented in the decimal form with one digit before the decimal point times 10 raise to the power.

For example :

5000 is written as $5.0\times 10^3$

889.9 is written as $8.899\times 10^{-2}$

In this examples, 5000 and 889.9 are written in the standard notation and $5.0\times 10^3$ and $8.899\times 10^{-2}$ are written in the scientific notation.

$8.89\times 10^{-2}$ this is written in the scientific notation and the standard notation of this number will be, 0.00889.

If the decimal is shifting to right side, the power of 10 is negative and if the decimal is shifting to left side, the power of 10 is positive.

(a) As we are given the 60200 L in standard notation.
