Why the rotation direction of water in a sinks changed after crossing the equator?
The twisting effect of the Coriolis force is real and does influence certain large things like the movement of air masses, but the effect is so small that it plays no role in determining the direction in which water rotates as it exits from a draining sink or toilet. The Coriolis effect produces a measurable effect over huge distances and long periods of time, such as storm systems, but don't apply to your bathroom or kitchen. Toilets and sinks drain in the directions they do because of the way water is directed into them or pulled from them. The configuration of taps, drains and the surface of the bowl is responsible for the direction of the water draining through, overwhelming the coriolis effect.
It's a bit of a urban myth. People on the equator sometimes demonstrate it to tourists, but these are rigged.
What else can I help you with?
What is the centripetal acceleration experienced at the equator due to the Earth's rotation?
The centripetal acceleration experienced at the equator due to the Earth's rotation is approximately 0.034 m/s.
To weigh less in the northern hemisphere you should move which direction?
To weigh less in the northern hemisphere, you should move closer to the equator. This is because the force of gravity is slightly weaker at the equator compared to the poles due to the Earth's shape and rotation.
How does the rotation of the Earth affect its shape?
The rotation of the Earth causes it to bulge slightly at the equator, making it slightly flattened at the poles and slightly wider at the equator. This shape is known as an oblate spheroid.
Can you balance an egg on the equator?
Yes, it is possible to balance an egg on the equator due to the Earth's rotation creating a slight bulge at the equator, providing a more stable surface for balancing objects.
Why can you balance an egg on a nail at the equator?
You can balance an egg on a nail at the equator because the Earth's rotation creates a force that helps keep the egg upright. This force is strongest at the equator, making it easier to balance the egg there.
Why is the Coriolis effect zero at the equator?
The Coriolis effect is zero at the equator because the rotation of the Earth is perpendicular to the direction of motion at the equator, resulting in no deflection of moving objects.
The crossing the line ceremony marks a ship's crossing the?
The ceremony is used to celebrate a person's first sea crossing of the Equator.
Why don't hurricanes cross the equator?
Hurricanes do not cross the equator because of the Coriolis effect, which is a force caused by the Earth's rotation. This effect causes storms in the Northern Hemisphere to rotate counterclockwise and storms in the Southern Hemisphere to rotate clockwise. As hurricanes approach the equator, the Coriolis effect weakens and eventually becomes too weak to sustain the storm's rotation, preventing it from crossing the equator.
What is used to determine the direction of the wind?
Wind direction is determined by friction ,or the lack thereof ,surrounding the earth surface. Warm air from the equator rises, moves towards the poles, falls and returns to the equator. crossing water decreases friction, crossing a mountain increases friction.
What is the rotation rate at the equator of the sun?
The rotation rate at the equator of the Sun is approximately 25 days, meaning that it takes about 25 days for the Sun to complete one full rotation at its equator.
Why do hurricanes not cross the equator?
Hurricanes do not cross the equator because of the Coriolis effect, which causes storms to rotate in a specific direction based on their location in the Northern or Southern Hemisphere. This effect prevents hurricanes from crossing the equator and moving from one hemisphere to the other.
Where does the crossing the line ceremony mark a ship's crossing?
When a ship crosses the Equator.
Which reference point established by scientists could be changed the equator or the prime meridian?
The equator is a fixed point of reference for the traversal of the sun and is the midpoint between the two tropics. The prime meridian, however, is a relative point based on time, which could be adjusted if the need arose.
Which direction does the sink water spin on the equator?
Contrary to popular belief, water swirling down the drain is no related to the Earth's rotation or the Coriolis effect. The swirling vortex over the drain is likely related to angular momentum; the distance from the center of the rotation determines the speed of the rotation. o
Is the speed of rotation at the equator greater than that in Canada?
Yes, the speed of rotation at the equator is faster than in Canada due to the larger circumference of the Earth at the equator. This difference in rotational speed is caused by the flattening of the Earth's shape at the poles, known as oblateness.
What is the centripetal acceleration experienced at the equator due to the Earth's rotation?
The centripetal acceleration experienced at the equator due to the Earth's rotation is approximately 0.034 m/s.
How long is the suns rotation?
25 days for a rotation at the equator, 34 days for a rotation near the poles.
