Answer:
The sun rays will be focused at the same distance from the mirror.
Explanation:
Laws of reflection do not depend on the refractive index n any form. Hence, the sun’s rays will be focused the same distance from the mirror.
73 Newton is the correct answer
Answer:
Kevin must have used simple random sampling.
Explanation:
We can say that Kevin used simple random sampling. This is because this type of sampling allows elements to be taken from a population in a completely random way, to form a sample. In this case, each element, or individual, as shown in the question above, has the same probability of being selected to compose the sample, since this selection is completely random.
Answer:
The risks and expense of manned deep water exploration must be balanced with the knowledge that will be gained.
Explanation:
The angle of the planet is mathematically given as
dY= 704 degrees
<h3>What angle has planet Y rotated through during this time?</h3>
With Kepler's third rule, which states that a planet's orbit squared is a function of cubed radius, we can prove that this is the case.
Generally, the equation for the period is mathematically given as
(periodX / periodY)^2 = (radius X / radius Y)^3
Therefore
(pX / pY)^2 = 4^3
(pX / pY)^2 = 64
\sqrt{(pX / pY )^2}= \sqrt{64}
(pX / pY=8
In conclusion, Because it takes 8 times longer to complete one orbit on planet X, planet Y travels 8 times farther than planet X does in the same time period...
planet Y travels ;
dY=8 * 88.0
dY= 704 degrees
