Answer: 1.65m
Explanation:
Refractive index in terms of the depth of liquid is the ratio of the real depth to the apparent depth of the liquid i.e Refractive index =Real depth/apparent depth
Refractive index of water given = 1.33
Real depth is the measure of how deep is the liquid while apparent depth is the depth at the surface of the liquid.
Real depth = 2.2m
Apparent depth =?
Applying the formula above
Apparent depth =Real depth/refractive index
= 2.2/1.33
= 1.65m
Therefore, the circle of light that exits the surface of the water when that light shines in the middle of the night is 1.65m wide
The answer is C, a peer group.
Answer: I am getting a result around the 54,800 area, so I am selecting the 55,000 HP answer.
How much work in J does the string do on the boy if the boy stands still?
<span>answer: None. The equation for work is W = force x distance. Since the boy isn't moving, the distance is zero. Anything times zero is zero </span>

<span>How much work does the string do on the boy if the boy walks a horizontal distance of 11m away from the kite? </span>
<span>answer: might be a trick question since his direction away from the kite and his velocity weren't noted. Perhaps he just set the string down and walked away 11m from the kite. If he did this, it is the same as the first one...no work was done by the sting on the boy. </span>
<span>If he did walk backwards with no velocity indicated, and held the string and it stayed at 30 deg the answer would be: </span>
<span>4.5N + (boys negative acceleration * mass) = total force1 </span>
<span>work = total force1 x 11 meters </span>

<span>How much work does the string do on the boy if the boy walks a horizontal distance of 11m toward the kite? </span>
<span>answer: same as above only reversed: </span>
<span>4.5N - (boys negative acceleration * mass) = total force2 </span>
<span>work = total force2 x 11 meters</span>
