Those changes in temperature are equal. The absolute (Kelvin) scale and the Celsius scale use the same size degrees, (but their zeros are set at different temperatures).
Their 'degree' is 0.01 of the difference between the boiling and freezing temperatures of water.
Answer:
The answer is <em>e.2</em>
Explanation:
We should make use of Snell's refractive law. The arriving wave has a certain velocity at T in a medium, then instantly it reaches a medium (same composition) at T' where velocity would either decrease or increase.
When the incidence angle is 30 °, and we want to make the refraction angle 90 ° such that no sound passes through the barrier (this would be named total internal refraction), so we want the second medium to be "faster" than in the first.

You can't see beyond a blind turn, so a mirror would allow you to see around the corner.
F - False.
The nucleus of an atom is positively charge.
