In a boat, the sail and jib have an essential role in moving the boat in the water. The jib is known as the sail, which is triangular in shape. It...Become a member and unlock all Study Answers Start today. Try it now Create an accoun...
In science, density is the ratio of the mass to the volume. For an object having irregular shape, we can solve its density by taking its mass by weighing and dividing by the local gravity. Then to measure its volume, we can submerge the object in a beaker having a known quantity of ...

Boats may be sailed using a jib alone, but more commonly jibs make a minor direct contribution to propulsion compared to a main sail. Generally, a jib's most crucial function is as anairfoil, increasing performance and overall stability by reducing turbulence on the main sail's leeward side....

Of course this is a very rough estimation, and you should definitely measure your sails, but for a quick cost estimation it will do. The surface factor will only work with a standard Bermuda sloop rig, using a 100% jib and regular main. The price of sail cloth per square foot: You wa...

Which instrument is used to measure altitude in aircraft? What are the three types of inclined planes? How to solve problems regarding inclined planes? a) How long would it take a 1.50x10^5kg airplane with engines that produce 100MW of p...
Answer and Explanation:1 The aeroplane consists of an arrangement of high power engines and wings; the high power engine creates a sufficient amount of speed to accelerate...
Density measure how compact a substance which is measured by diving mass by its volume. Buoyancy, on the other hand, is the force that a fluid exerts on an object that is submerged to it. A dense object will eventually sink in water and float if it is less dense than the fluid....
