When the wind doubles does the pressure in the sails increase 8 times?

When the apparent wind speed is doubled, the pressure on the sail is quadrupled. That is because the pressure on the sail (or the side of your house or a billboard sign) is proportional to the square of the speed of the wind. If the wind speed triples, then the pressure goes up by a factor of nine, because three squared is nine.

If the two sides of a cell double in length its volume increases by how many times?
If the sides of a cell doubles, this volume will increase by 8 times. Here is an explanation: Say you have a cell with the side dimension equal to n. The volume of the cube is n3 Double the side lenght to 2n The volume is now (2n)(2n)(2n) = 8n3
How do you find altitude pressure?
Pressure= Force/Area Pressure of a Liquid is density times gravity times height
What does a 1.0 increase on the Richter scale mean?
It means that the maximum amplitude of the seismic waves recorded is 10 times bigger for every 1.0 increase. This is equivalent to a 32 times increase in the amount of energy released by the earthquake.
Why do sun spots increase?
The number of sunspots increases at times, and decreases at others. It will not continue to increase indefinitely.
What is the property that is affected by the number of times particles of gas hit the inside of the container?
Pressure... hope I helped! :D
If lateen sails were triangular what were the square sails called in medieval times?
Square sails are not truly square but rectangular with a longer long side on the bottom perimeter of the sail. They were and are referred to as "four-cornered" sails.
What would you do to the volume of a gas to reduce its pressure to one quarter of the original value?
You could increase its volume or cool it or both.
On the decibel scale an increase of 10 decibels means an intensity increase of times?
10 decibels increase mean measured on a sound pressure level meter. SPL meter. Forget the intensity, because the ear drums and the microphone diaphragms are moved by the sound pressure. 10
These control kidney function and increase blood pressure and heart rate during times of stress?

If current in an electric stove is doubled how will the thermal energy produced per unit time change?
P = I2R (power = current squared times resistance). Therefore, if the current doubles, the amount of dissipated electrical energy will increase by a factor of 4.P = I2R (power = current squared times resistance). Therefore, if the current doubles, the amount of dissipated electrical energy will increase by a factor of 4.P = I2R (power = current squared times resistance). Therefore, if the current doubles, the amount of dissipated electrical energy will increase by a factor of 4.P = I2R (power = current squared times resistance). Therefore, if the current doubles, the amount of dissipated electrical energy will increase by a factor of 4.
How can you increase water pressure from a well?
Simply increase the height of the tank as the pressure is a constant (.434) times the height, or approximately 1/2 PSI per foot.
What happens to the pressure if the temperature in K is doubled?
The initial pressure is halved. Use Boyle's law that relates pressure & volume at a constant temperature. P1V1 = P2V2 In this case the V1(initial volume) is doubled so V2 = 2V1 P2 = P1V1/V2 = P1V1/2V1 P2 = (1/2)*P1
At what times does the Aqaba-Nuweiba Ferry sail?
Aquaba Nuweiba ferry sails at 11 am in the morning
What are sails made out of?
In the past, sails were made out of a material called 'sailcloth' or 'canvas' which was originally made from hemp/flax fibers (linen). After the discovery of cotton this too was used as the source of fiber. In modern times, sails are rarely made from natural fibers and most sails are now made from synthetic fibers including nylon, polyester, aramids and carbon fibers. These sails are stronger and will not let the wind though. (In the past sail canvas had to be sluiced down to make it impervious to the wind - this made the sails and rigging heavy).
Does partial pressure of oxygen increase during exercise?
You can consume up to ten times as much oxygen in exercise as at rest, and produce the same increase in CO2.
Would your penis be bigger in space because there is less pressure?
Yes because the force of gravity times the gerth divided by the volume would increase
What happens to the pressure of a gas if the volume of a gas is tripled at a constant temperature?
The pressure is reduced to one third of the original pressure. The pressure will stay the same you are only changing the volume
