Answer:
<h2>A. Nearsightedness</h2>
Explanation:
A nearsightedness is an eye defect that occurs when someone is only able to see close ranged object but not far distance object. According to the question, if the length of my eye decreases slightly as I age, this means there is a possibility that I will find it difficult to view a far distance object as I age.
At 70, once my eyes had decreased slightly in length, this means I will only be able to see close ranged object but not far distant object, showing that I am now suffering from nearsightedness according to its definition above.
Answer:
v = 282.84 m / s
Explanation:
The speed of a wave in a wire is given by the equation
.v = √ T /ρ
Where v is the speed of the wave, T the tension in the wire and ρ the density of the wire
If the tension is doubled
T = 2T₀
v = √ (2T₀ / ρ)
v = √2 √ T₀ / ρ
v = √2 v₀
calculate
v = √2 200
v = 282.84 m / s
Since all of the appliances ... and everything else in the house that's
plugged into a wall outlet ... are all in parallel, they don't have any
effect on each other. They don't know about each other. The
question asks about the frying pan, so the toaster and the lamp
have no effect on the answer.
The frying pan has 120 V applied to it, and it produces 1592 watts
of heat.
Power = (voltage)·(current)
1592 watts = (120 v)·(current)
Divide each side by 120v:
Current = (1592 watts) / (120 volts)
Current = 13.27 Amperes
