Explanation:
If long sight means farsighted, then here's your answer:
Farsightedness is when the lens has difficulty focusing on nearby objects. Sufferers must squint to see the nearby objects. Reading, writing, and drawing for longer periods of time can cause eyestrain and headache.
Being farsighted can be corrected with prescription glasses or contact lenses or surgery.
Answer:
Explanation:
The magnitude of the electrostatic force between two charges is given by the equation:
where:
is the Coulomb's constant
are the two charges
r is the separation between the two charges
And the force is:
- Attractive if the charges have opposite sign
- Repulsive if the charges have same sign
In this problem, we have:
F = 3 N is the force between the proton and the electron
is the magnitude of the charge of the proton and the electron
Therefore, solving for r, we find the separation between the two particles:
Answer:
Water can produce electricity. Water falls from the sky, converting potential energy to kinetic energy.
Explanation:
Answer:
It will have an acceleration of .
Explanation:
Newton’s second law is defined as:
(1)
Equation 1 can be rewritten for the case of the acceleration:
The force and the acceleration are directly proportional (if one increase the other will increase too).
But 1 N is equivalent to
So a body will have an acceleration as a consequence of the action of a force.
