Explain why a black and white aeronautical map would be difficult to use

1 answer:

5 0

Aeronautical maps are usually meant to be used by pilots and air aviation professionals in other to navigate or traverse though the sky. With various elements such as vegetation, hills, valleys being depicted by color coded keys or legend. Hence, the absence of color on an aeronautical map make the <em>representation of elements very difficult</em>.

Visual map interpretation is usually aided by the use of legends. The legend hold the key to the elements which are represented on the map. Usually, a combination of colors and shapes makes up the legend and makes map interpretation easy.

Therefore, the absence of various color palletes for representation on a black and white aeronautical map will make it difficult to use.

A binary star system consists of two stars of masses m1 and m2. The stars, which gravitationally attract each other, revolve aro

mote1985 [20]

Answer: $a_{2}=\frac{m_{1}}{m_{2}} a_{1}$

Explanation:

The rest of the question is below:

Find a2, the magnitude of the centripetal acceleration of the star with mass m2.

Assuming both stars are describing a uniform circular motion, their acceleration vector is directed towards the center of mass of the system (that's why it's called centripetal acceleration).

Now, according to Newton's 2nd law, the force $F$ is directly proportional and in the same direction as the acceleration.

For $m_{1}$ :

$F_{1}=m_{1}a_{1}$

For $m_{2}$ :

$F_{2}=m_{2}a_{2}$

If the centripetal force is the same for both stars:

$F_{1}=F_{2}$

$m_{1}a_{1}=m_{2}a_{2}$

Isolating $a_{2}$ :

$a_{2}=\frac{m_{1}}{m_{2}} a_{1}$

A chain reaction results when a uranium atom is struck by a/an ______________released by a nearby Uranium atom undergoing fissio

finlep [7]

Answer:

Chain reaction is possible by neutron

Explanation:

Nuclear reaction is mainly two types,

⇒ Nuclear Fission : heavy atom split into two light atom.

Ex. Uranium, thorium

⇒ Nuclear fusion : lighter atom combine together

Ex. Hydrogen to helium

In fusion reaction the large amount of energy is produced as compare to fission reaction.

Sun gets brighter by fusion reaction.

In case of uranium fission reaction is possible by colliding neutron.

What factors determine the distance at which two atoms form a bond ?

dsp73

Answer:

The length of the bond is determined by the number of bonded electrons (the bond order). The higher the bond order, the stronger the pull between the two atoms and the shorter the bond length. Generally, the length of the bond between two atoms is approximately the sum of the covalent radii of the two atoms.
