Which statement is true about a farsighted (hyperopic) eye?
1 answer:
The correct answer is C. I leave an attached image to have a clearer idea of the light process that uses the Light when entering the eye. When you have farsightedness, the image is formed behind the eye so the defective effect is generated.
What is sought with the lenses is to correct this condition and put the image back at the point of the retina.

Answer:
96%
Explanation:
To find the values of the motor efficiency you use the following formula:
P_o: output power = 864J/0.5min=864J/30s=28.8W
P_i: input power = I*V = (3A)(12V) = 36W
By replacing this values you obtain:
hence, the motor efficiency is about 96%
traslation:
Pentru a găsi valorile eficienței motorului, utilizați următoarea formulă:
P_o: putere de ieșire = 864J / 0.5min = 864J / 30s = 28.8W
P_i: putere de intrare = I * V = (3A) (12V) = 36W
Înlocuind aceste valori obțineți:
prin urmare, eficiența motorului este de aproximativ 96%
