Answer:
True.
Explanation:
Total internal reflection is bound to occur when light travels from dense medium to less dense.
From the table given in the question above, we obtained:
Refractive Index of Crown glass = 1.52
Refractive Index of Asphalt = 1.635
From the above, Crown glass has a lower refractive index when compared to Asphalt. This means that Crown glass is less dense than Asphalt.
Therefore, total internal reflection will not occur when light travels from Crown glass to Asphalt because Crown glass is less dense than Asphalt.
Answer:
In collision between equal-mass objects, each object experiences the same acceleration, because of equal force exerted on both objects.
Explanation:
In a collision two objects, there is a force exerted on both objects that causes an acceleration of both objects. These forces that act on both objects are equal in magnitude and opposite in direction.
Thus, in collision between equal-mass objects, each object experiences the same acceleration, because of equal force exerted on both objects.
Answer:
h = 120 m
h = 60 m
when rounded to two significant digits.
Explanation:
height of the higher ball drop point
h = ½gt² = ½(9.8)5.0² = 122.5 m
lower ball drop point
h = ½(9.8)(5.0 - 1.5)² = 60.025
Answer:
GPE = mgh = 5.00 kg .
2.20 + 0.30 m = 122.5 J
Explanation:
Putting effort at point IV of this lever gives no mechanical advantage because it <em>requires a greater force.</em> So the correct answer is <em>C)</em>.
