Deep ocean currents form when denser ocean water sinks. The flow of deep currents is also affected by the Coriolis effect and by

continental deflection.
What is the order in which deep ocean currents will form?


a. Water cools and becomes more dense. Dense water sinks towards the ocean floor. Warm surface currents flow toward the polar region. Energy from the warm water is transferred to the cooler atmosphere.

b. Warm surface currents flow toward the polar region. Energy from the warm water is transferred to the cooler atmosphere. Water cools and becomes more dense. Dense water sinks towards the ocean floor.

c. Water cools and becomes more dense. Warm surface currents flow toward the polar region. Dense water sinks towards the ocean floor. Energy from the warm water is transferred to the cooler atmosphere.

d. Energy from the warm water is transferred to the cooler atmosphere. Water cools and becomes more dense. Dense water sinks towards the ocean floor. Warm surface currents flow toward the polar region.

Why did Aristotle's geocentric theory fail to match the expected predictions?
NNADVOKAT [17]

Aristotle's geocentric theory failed to match the expected predictions because a few celestial objects appear to have retrograde motion.

Answer: Option B

<u>Explanation:</u>

Aristotle’s theory states that all the bodies in universe rotate around the earth, and earth is located at the centre. But, the most serious challenge it was given was that, the difference found in the paths of revolution of mercury and Venus. They are revolving around the sun, and not the earth, periodically.

This is the significant drawback, and major factor for the Copernicus and the other models to be achieved. The mercury and Venus, closest planets to earth, and the sun too, are not following the earth’s path. And hence, upon studying clearly, all celestial bodies do not follow a path round the earth, but around a fireball, that is sun.

The mass of a steel wrecking ball is 1.50 E3 kg. What power is used to raise it to a height of 40.0 m if the work is done in 20.
Yakvenalex [24]
Given,

Mass of the ball (m) = 1.50 x 10³ kg = 1500 kg
Height raised = Displacement of the ball (D) = 40.0 m
Time taken (t) = 20 seconds

Power = Work done(W) ÷ time taken (t)

Work done (W) = Force (F) x Displacement (D)
Force (F) = Mass (m) x Acceleration due to gravity (g)
Acceleration due to gravity for earth (g) = 9.81 m/s²
Therefore,

Force (F) = 1500 x 9.8 = 14715 N

Work done = Force x Displacement = 14715 x 40 = 588600 Joules

Now, 
Power = Work done ÷ time taken = 588600 ÷ 20 = 29430 Watts

What does 760mmHg represents??​
malfutka [58]

Explanation:

760 mmHg (millimeters of mercury) is a measure of atmospheric pressure.  It represents the height of a column of mercury at which the static pressure at the bottom is equal to the atmospheric pressure.

1 atm = 760 mmHg = 101,325 Pa = 14.7 psi

Rony fills a bucket with water and whirls it in a vertical circle to demonstrate that the water will not spill from the bucket a
Romashka-Z-Leto [24]

Answer:

0 N, 3.49 m/s

Explanation:

Draw a free body diagram for the bucket at the top of the swing.  There are two forces acting on the bucket: weight and tension, both downwards.

If we take the sum of the forces in the radial direction, where towards the center is positive:

∑F = ma

W + T = m v² / r

The higher the velocity that Rony swings the bucket, the more tension there will be.  The slowest he can swing it is when the tension is 0.

W = m v² / r

mg = m v² / r

g = v² / r

v = √(gr)

Given that r = 1.24 m:

v = √(9.8 m/s² × 1.24 m)

v = 3.49 m/s
