Answer:

Bifocal lenses are used for people who are both nearsighted and farsighted. It is common for people who are over the age of 40 to begin to notice a change in their vision and require the need for bifocals. As we age, our eyes begin to have trouble focusing on objects at different distances away.

Answer:

People have to wear bifocals most commonly because of a condition called presbyopia. This condition occurs naturally. It causes difficulties in the eye’s focusing abilities. Bifocals work to help the eyes focus more clearly, which is why people have to get them.

If the net force an object at rest is zero the object will remain at rest. <br> True or false

FromTheMoon [43]

True

Explanation:

If the net force on an object at rest is zero, the object will remain at rest. This is one of the postulates of newton's law of motion.

Newton's first law of motion states that "an object will continue in its state of rest or uniform motion unless if it is acted upon by an external force. "

If no net force acts on a body, it will forever remain at rest.
The force on a body causes its motion and acceleration.
A body will continue in uniform motion if no external force acts on it.
