Explanation:
Friction can be bad by being too strong or too weak.
<span>Sometimes, when it is too strong, it decreases efficiency since some energy is wasted and turns to heat. Friction can also d</span><span>amage equipment/objects like when you slide it on the floor.

When friction is too weak, like for instance when there is black ice- our center of gravity is displaced too quickly and we can fall. Likewise, if there is a lot of slush on the ground, cars can slip and slide.

Answer:
The power of top half of the lens is 0.55 Diopters.
Explanation:
Since, the person can see an object at a distance between 34 cm and 180 cm away from his eyes. Therefore, 180 cm must be the focal length of the upper part of lens, as the top half of the lens is used to see the distant objects.
The general formula for power of a lens is:
Power = 1/Focal Length in meters
Therefore, for the top half of the lens:
Power = 1/1.8 m
<u>Power = 0.55 Diopters</u>
