there callled tidal bulgdes and they are on both poles

The two bulges are called tidal bulges. There are two tidal bulges on opposite sides of Earth. One is beneath the moon and the other is opposite to that. The one below the moon is thought of as gravitational. It is produced by gravitational attraction between water molecules in the ocean and the moon.

Now, about the other bulge. Think about inertia and what happens when masses rotate around a single point. Imagine yourself swinging a bucket of any liquid with your arm in a circular gesture. Even as the bucket goes over your head, the water is still held in the bucket and doesn't splash all over you. This rotation creates a centrifugal force. A similar event occurs during the lunar month as the earth/moon system rotates. The moon orbits the earth, but the rotation axis for this orbit isn't earth's center. Both the moon and Earth move during the roughly 28-day period it takes for the orbit, and because of this, water in the ocean is thrown to the outside, the same as the water in your bucket. The tidal bulge on the opposite side of Earth from the moon is produced by this inertial effect, referred to as centrifugal force.

A runner wants to run 13.1 km . She knows that her running pace is 6.2 mi/h .How many minutes must she run? Hint: Use 6.2 mi/h a

frutty [35]

Answer:

79 minutes

Explanation:

1) Convert the distance, 13.1 km to miles

Conversion factor:

1 = 1 mi / 1.61 km

13.1 km [ 1 mi / 1.61 km ] = 8.1336 mi

2) Use 6.2 mi/h as a converstion factor between distance and time

8.1366 mi × 1 / [6.2 mi/h] = 1.3124 h

3) Convert 1.3124 h to minutes

1.3124 h × [ 60 min/h] = 78.7 min

Rounding to the nearest minutes (two significant figures):

79 min ← answer

Anomalous data shows on a graph as a

KiRa [710]

Anomalous data on a graph would show up as say a very high or very low value which does not fit in with the normal values which may be background values.If it was a straight line graph then the anomalous point would plot well above or below the line or if it was a bar graph ie a histogram it would be much higher or lower than the surrounding data. In mineral exploration, anomalies are looked for in say geophysics or geochemistry data values for high or low magnetism or conductivity or high chemical values indicating the presence of valuable minerals at that point.

Which statement best describes the compressibility of a gas?

maria [59]

The answer to the question stated above is:
 Gas is easily compressible because the molecules of a gas are much further apart than those of a solid.

characteristic properties of gases:

(1) they are easy to compress,

(2) they expand to fill their containers, and

(3) they occupy far more space than the liquids or solids from which they form.

Choose whether the statements about oil sands are true or false. The viscosity of bitumen is about 100 times greater than the vi

Alexxx [7]

The First 2 statements stated above were false whereas the third one is a true statement.

Explanation:

The viscosity of bitumen is about 100 times greater than the viscosity of water - False

Reason - The viscosity of bitumen is about not 100 times greater than the viscosity of water, it is actually 100, 000 times greater.

Oil from oil sand deposits is only obtained by first heating the sands at high temperatures is False.

Reason- Oil from oil sand deposits is not obtained by first heating the sands at high temperatures but by using steams

Oil sands contain sand, water, and light crude oil is true.
