<h2><u>Explanation:</u></h2>

<em>m = h₂/h₁</em>

Here,

  • <em>m</em> = Magnification
  • <em>h₁ </em>= Height of the object
  • <em>h₂</em> = Height of the image formed by the concave mirror

Magnification given is (-3). The linear magnification here is negative.

This implies that <em>h₂ < h₁</em> because <em>m < 1</em>.

Therefore, the image formed is <u>real and inverted</u>. It is <u>smaller than the object</u>. So, the image is formed between the Centre of Curvature & the Focus.

<em>[NOTE: If the image is highly reduced, it is formed at the focus.]</em>

Answer:HERE IS YOUR ANSWER

THE POINTS ARE

IF WE PUT THE OBJECT BETWEEN THE FOCUS

AND THE POLE

THEN THE IMAGE FORMED WILL be MAGNIFIED

If that’s not what you are looking for, try this one:

For concave mirror the virtual image is formed when the object is kept in between the pole and the focus.  

Given here the "size of the image" is twice to that of the object.

Hence, it is consider that the magnification is +2.

So, the magnification value is positive and the image formed will be "virtual and erect". Thus, the object should be kept in between the "pole and the focus" in concave mirror."

Tatiana [17]

Answer:

The correct answer is;

Change of phase.

Explanation:

When the physical state in which a substance exists in nature changes to another physical state such as a change from solid state to a liquid stat or from a liquid state to a gaseous state, the substance is said to have undergone a phase change, or phase transformation.

The state of a substance will change, depending on the surrounding temperature and the applied pressure and the energy required for the substance to change its state is known as latent heat.

The observed plateaus are periods the latent heat is absorbed to completely change the phase of the substance.

A runner of mass 80 kg is moving at 8.0 m/s. Calculate her kinetic energy. ​
lana [24]

Answer:

2560J

Explanation:

By definition the kinetic energy can be calculated in the following way:

K = (mv²)/2 = 80kg·(8.0m/s)²/2 = 2560 J
