The answer is B because it literally says it right there, and I don't wanna make it impossibly confusing for a middle school student, lol.
Philosophy, any more questions by any chance?
In the Newtonian theory of gravitation, the effects of gravity are always attractive, and the resulting force is calculated with respect to the center of gravity of both objects. The law of universal gravitation formulated by Isaac Newton postulates that the force exerted by a point particle with mass M on another with mass m is directly proportional to the product of the masses (and the Universal Gravitation Constant), and inversely proportional to the square of the distance (r) that separates them:
Therefore the correct answer is 2.
Answer:
Required horizontal distance is 0.9279 meters
Explanation:
The situation is represented in the attached figure
The horizontal distance can be seen to be equal to
In the upper triangle we have
Now the angle can be calculated using Snell's law
By snell's Law we have
Since light comes from air thus
Light enter's the water thus we have
Applying values we calculate as
Now in the attached figure we have
Solving for we get
thus the required horizontal distance is
