The image of the object is 8cm to the left of the lens (D)

What is the image of an object?
The image of an object is said to be the location where light rays from that object intersect with a mirror by reflection.
It is calculated thus:
1÷v = 1÷f - 1÷u
<h3>How to calculate the image of an object</h3>
From the formula
1÷v = 1÷f - 1÷u
<h3>
Where </h3>
V = image distance fromthe object
U = object
f = focal length
Substitute the values
1÷v = 1÷8 - 1÷ 4
1÷v = - 1÷8
Make v the subject of formula
v = -8cm
Therefore, the image of the object is 8cm to the left of the lens (D)

Explanation:
Pls mark as brainliest
Answer:within the focal length of the lens, provided the focal length is shorter than the near point distance.
Explanation:Hope it helps
"Free fall" means that gravity is the ONLY force acting on the object. If there's air resistance, then it isn't free-fall.
Objects that fall near earths surface are ALWAYS falling through air, unless they're inside some kind of a vacuum chamber with all the air removed from it.
The characteristics shared by both heating and cooling curves is that phases changes when the temperature stays the same.
<h3>What is heating and cooling?</h3>
Heating is the process by which the temperature of a place or substances or object is increased.
Cooling Is the process of lowering the temperature of a substance or object by using conditioners or by freezing .
Therefore, The characteristics shared by both heating and cooling curves is that phases changes when the temperature stays the same.
