Answer:

central nervous system

peripheral nervous system

Explanation:

The nervous system has two main parts: The central nervous system is made up of the brain and spinal cord. The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body.Oct 1, 2018

Two long, straight wires are parallel and 20 cm apart. One carries a current of 2.2 A, the other a current of 5.9 A. (a) If the

Leya [2.2K]

Answer: $1.298\times 10^{-5}\ N/m$

Explanation:

Given

Current in the first wire $I_1=2.2\ A$

Current in the second wire $I_2=5.9\ A$

wires are $20\ cm$ apart

Force per unit length between the current-carrying wires is

$\Rightarrow \dfrac{F}{l}=\dfrac{\mu_oI_1I_2}{2\pi r}$

Force exerted by the wires is the same

Put the values

$\Rightarrow \frac{F}{l}=f=\dfrac{4\pi \times 10^{-7}\times 2.2\times 5.9}{2\pi \times 0.2}=1.298\times 10^{-5}\ N/m$

This force will be repulsive in nature as the current is flowing opposite

Decide whether each statement describes mass or weight.

vova2212 [387]

Mass is measured in kilograms.
Mass does not change when gravity changes.
Mass is the amount of matter in something.

<u>Weight</u>

Before I answer, we have to know weight formula. Weight = mass × acceleration due to gravity.
Therefore, weight is measured in Newtons.
Weight changes when gravity changes. This is because weight is dependent on acceleration due to gravity.
Weight is a gravitational force.

Hope you could understand.

If you have any query, feel free to ask.
