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.
No, the pressure in the sails does not increase by 8 times when the wind doubles. The pressure in the sails is directly proportional to the square of the wind speed increase. So, if the wind speed doubles, the pressure in the sails will increase four times, not eight times.

The number of molecules in a container is tripled and the Kelvin temperature doubled The volume remains unchanged The new pressure will be how many times greater than the original pressure?
The new pressure will be six times greater than the original pressure. This is because pressure is directly proportional to the number of molecules and temperature in Kelvin, according to the ideal gas law. Since both the number of molecules and temperature have increased, the pressure will triple for the increase in molecules and double for the increase in temperature, resulting in a total increase of 6 times.
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
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.

These control kidney function and increase blood pressure and heart rate during times of stress?

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
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.
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).
If current in an electric stove is doubled how will the thermal energy produced per unit time change?
If the current in an electric stove is doubled, the thermal energy produced per unit time will increase by a factor of four. This is because the power dissipated in a resistor is proportional to the square of the current (P = I^2 * R), so doubling the current will result in four times the power output.
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
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
What would you do to the volume of a gas to reduce its pressure to one quarter of the original value?
To reduce the pressure of a gas to one quarter of its original value, you would need to increase the volume of the gas by a factor of 4. This can be achieved by expanding the container or increasing the space available to the gas while keeping the temperature constant. Following Boyle's Law, pressure is inversely proportional to volume when temperature is constant.
Were viking boats powered by motors?
No,in ancient times sails and oars were used to power the viking ships also known as longboats.
