Answer:

(D) Water is denser than oil but less than syrup.

Explanation:

Given:

A picture of a jar containing three liquids.

The position of the syrup is at the bottom of the jar. The position of water is in middle and the oil is at the top.

We know that, the oil is the lightest in density when compared to syrup and water. So, it is at the top.

Now, since water is in the middle of the two, it means that density of water is greater than that of oil but less dense than that of syrup.

So, the density of the syrup is the greatest. Hence, it sits at the bottom.

Therefore, the best explanation is that water being less dense than syrup but more dense than oil, will be in the middle of two.

This explains the position of all the three liquids. Water is in the middle, oil at top and syrup at bottom.

So, the last option is correct.

Answer:

Here the source is moving away from the observer so frequency will be smaller than the actual frequency and since the speed is increasing so the frequency is decreasing with time so correct answer is

D) lower than the original pitch and decreasing as he falls.

Explanation:

As we know by the Doppler's effect of sound we have

so we will have

$f = f_o(\frac{v}{v + v_s})$

so here when source moves away from the observer with a some speed then the frequency of the sound observed by the observer is smaller than the actual frequency

Here we know that the speed of the source is increasing with time as the source is falling under gravity

So we can say that the pitch of the sound will decrease with time

The Coriolis effect is the result of which of these?

Anarel [89]

The coriolis effect was discovered in the 19th century by Gaspard. C. Coriolis. It simply relates to anything that moves freely on the surface of the earth including apparent curvature global winds and ocean currents.
This curvature is mainly due to the rotation of the earth around its axis.

Answer:
<span>A.) The rotation of Earth on its axis</span>
