You need to draw two lines from the head of the arrow: one parallel to the axis (which will be bent) and the other one passing through the center of the converging lens <span>(which will continue straight) </span>and see where they intersect.

If the arrow is at an infinite distance, the image will be point-like in F.
If the arrow is at a distance greater than 2F, the image will be upside down between F and 2F.
If the arrow is at a distance of 2F, the image will be upside down in 2F.
If the arrow is at a distance between F and 2F, the image will be upside down beyond 2F.
If the arrow is at a distance F, all rays proceed parallel to each other and no image is formed.
If the arrow is at a distance smaller than F, the image will be virtual.

Therefore, the correct matches are 1B, 2C, 3D, and 4A.

Is this a scientific model? Use complete sentences to explain why or why not.
grin007 [14]

Answer:

A scientific model is an activity that is aimed at making a specific part or feature easier to understand and define.

Modeling is an essential scientific discipline and is used in the fields of education. Modeling seems to represent empirical objects, phenomena in a logical and objective way.

The oval-shaped world map showing vegetation in green color is a 2D model of the entire earth and demarcates us the world vegetation distribution and growth.  

Hence this is a scientific model as its helps in visualizing the land surface of the earth on paper.

Explanation:

Yes because a scientific models doesn't have to be complex, just like this one

What can be inferred when an atom is electrically charged?
Elena-2011 [213]

When an atom becomes electrically charged the number of electrons or protons stops and they are not equal again. The "extra" electron or proton is not balanced by something inside the atom any longer and it starts attracting itself to othet protons or electrons in other atoms.

<h3>What is atomic structure?</h3>

An atomic structure comprises of positively charged nucleus which is surrounded by negatively charged particles called electron and neutron which is neutral charged.

Unlike charges attract each other while like charges repel each other.

Therefore, When an electron is fully charged, the number of electrons will stop to be unequal again.

What is the relationship between mass, volume, and density? What is the relationship between mass, volume, and density? Density
kirza4 [7]

Answer:

A. Density is proportional to mass and inversely proportional to volume

Explanation:

Density can be defined as the property that matter has, whether solids, liquids or gases, to be compressed in a given space.

The expression that relates the density with the another values is given by,

\rho= \frac{m}{V}

Where,

\rho \propto m  (It is directly proportional to the mass of the object)

\rho = \frac{1}{V}(It is inversely proportional to the volumen of the object)

<em>Therefore density is directly proportional to the mass and inversely proportional to the volumen.</em>

Help please....................​
Marina86 [1]

Answer:

a. arranging from least to higher pressure exerted by object B ,D A, C

b object B exert maximum pressure on surface because pressure is indirectly proportional to the surface area from the above figure we can easily conclude that object a have least surface area so, it exert more pressure on surface.

c.object C exert minimum pressure on surface because pressure is indirectly proportional to the surface area from the above figure we can easily conclude that object a have large  surface area so, it exert less pressure on surface.
