Why does your blood rush from your head to your feet when you come to a stop in a descending elevator?
Your brain needs a constant amount of blood pumped up to it in order for it to function properly. (If you have a poor blood circulation, you should consult your local doctor).
The blood pumped by the heart is sent to different parts of the body through blood vessels called Arteries. One of it's destinations is to your brain (carries oxygen, glucose etc to the cells). In order for the blood to be pumped up to your head the blood needs to be under pressure. When the blood is under pressure it pumps further, which is what is needed for the blood to be pumped up to your brain.
The blood does not need to be under pressure when it travels to your feet since it can work together with gravity to reach it. But when the heart wants to pump blood up to your brain, it has to work against gravity which is why pressure is needed.
Branchiocauras's have necks that can measure up to 5-8 meters long. The blood pumped by the heart needs to be under a tremendous amount of pressure so that enough blood reaches your brain.
What else can I help you with?
When riding a descending elevator that stopped suddenly the blood rushes from your head to your feet.how does this considered as a manifestation of newtons first law?
When the elevator suddenly stops, your body tends to remain in motion due to inertia (Newton's First Law). As a result, your blood continues moving downward towards your feet until it catches up with your body's new motionless state. This is why you may feel a momentary sensation of blood rushing from your head to your feet.
What is an average speed of a elevator?
The average speed of an elevator varies, but it typically ranges from 500 feet per minute to 2000 feet per minute. However, it may be faster in some high-speed elevators in skyscrapers.
What happens to your weight if you are in an elevator traveling upward at a constant speed?
Your weight (the force you feel at the soles of your feet) in an elevator traveling at any constant speed in anydirection would be the same at any instant as it would be if you were in that elevator in the same place, stopped. For practical purposes, it would be the same as it would be when you're standing on the ground. Technically, weight changes with altitude, but for any existing building the difference between your weight at the lowest and highest points of the building will be so slight as to be undetectable. You'd probably lose more weight due to evaporation of moisture in perspiration and exhaled breath during the elevator ride than you would due to the slight reduction in gravity resulting from your moving a bit further from the surface of the Earth.In order for your perceived weight to change, there has to be an acceleration. Constant speed/velocity is not acceleration. You would feel a change in weight as the elevator slowed down or sped up, but you would feel your "normal" weight once the elevator reaches constant speed/velocity.
Is body heat lost through feet?
Yes, body heat can be lost through the feet due to the large number of blood vessels in the feet that can release heat into the environment. Wearing socks and appropriate footwear can help to minimize heat loss through the feet.
How fast does a high speed elevater go?
High speed elevators typically travel at speeds between 1,000 to 2,000 feet per minute, with some even reaching speeds up to 3,500 feet per minute. The speed of an elevator can vary depending on factors such as building height, design, and technology used.

When An elevator is 180 feet above the first floor and Each second it descends twelve feet what integer is the change in the height of the elevator each second?
The change in the height of the elevator each second is -12 feet. The negative sign indicates that the elevator is descending, while the magnitude of 12 feet represents the rate of descent. So, the integer representing the change in height is -12.
It takes an elevator 75 seconds to go 500 feet How fast is the elevator going?
The speed of the elevator is 6.67 feet per second (500 feet/75 seconds).
What is the answer of an elevator travels 310 feet in 10 seconds. At that speed how far can this elevator travel in 12 seconds Explain your reasoning.?
At 31 fps, the elevator will travel 372 feet in 12 seconds.
An elevator weighs 3500 pounds It is pulled upward a distance of 30 feet at a constant speed in 10 seconds A find the work done in lifting the elevator Bfind the speed of the elevator?
A. The work done in lifting the elevator can be calculated using the formula: Work = Force × Distance. The force is equal to the weight of the elevator, which is 3500 pounds, and the distance is 30 feet. Therefore, Work = 3500 pounds × 30 feet = 105,000 foot-pounds. B. The speed of the elevator can be found by dividing the distance by the time taken. Speed = Distance / Time = 30 feet / 10 seconds = 3 feet per second.
What is the velocity of an elevator climbing 32 feet per second?
It's 32 feet per second upward.
How much did an elevator cost in the 1800s?
Today it would be $1500 for an elevator that would go 50 feet up. In 1800's it would cost $80.
How do you not break an egg from a 25 feet building?
Put it in the elevator and send it to the first floor :)
What is an average speed of a elevator?
The average speed of an elevator varies, but it typically ranges from 500 feet per minute to 2000 feet per minute. However, it may be faster in some high-speed elevators in skyscrapers.
What time would it take to hit the ground if an aircraft at 36000 feet was descending at a rate of 300 feet per minute?
36000/300= :120
What is the speed of an object descending at 6 feet per second?
The speed is 4.1 miles per hour.
If an elevator travels 20 feet per second then how long would it take to travel 396 feet?
396/20 = 19.8 seconds
