What else can I help you with?
When operating a PWC at greater than no wake or idle speed how far away must you stay from a swimmer in the water?
50 feet
When you are operating a PWC and you are in a swimmer area when do you have to into no wake speed?
When operating a Personal Watercraft (PWC) in a designated swimmer area, you must reduce your speed to no-wake speed as soon as you enter the area. This typically means you should avoid creating any significant wake, which can pose a danger to swimmers. It's essential to maintain this speed until you are safely out of the swimmer area to ensure the safety of all individuals in the water. Always be aware of local regulations, as they may vary by location.
Is the speed in water vapor greater than speed in water?
Not the speed of sound.
When operating at GREATER THAN headway speed how far must a ski craft stay from swimmers in the water?
When operating at greater than headway speed, a ski craft must maintain a distance of at least 100 feet from swimmers in the water. This safety regulation is implemented to prevent accidents and ensure the safety of individuals in the water. Operators must always be vigilant and adhere to local laws and guidelines regarding safe distances.
Should you save a man who know how to swim or a woman who don know how to swin?
Save the non-swimmer - their need is greater ! The swimmer can at least tread water until they're rescued !
Is the speed of sound in steel greater than speed in water?
Yes.
When operating a pwc at greater than 6 knots how far away must you stay from persons in the water?
When operating a personal watercraft (PWC) at speeds greater than 6 knots, you must maintain a distance of at least 100 feet from persons in the water. This distance helps ensure the safety of swimmers, divers, and other individuals near the water. Always be aware of your surroundings and adjust your speed accordingly to prevent accidents.
When You are operating a vessel at greater than slow no wake speed. How far must you stay away from swimmers downed skiers or persons wading in the water?
When operating a vessel at greater than slow no wake speed, you must stay at least 100 feet away from swimmers, downed skiers, or persons wading in the water. This distance helps ensure the safety of individuals in the water and minimizes the risk of accidents caused by boat wakes or proximity. Always be vigilant and follow local regulations, as distances may vary by jurisdiction.
What moves a swimmer forward in the water?
The answer is: The swimmer exerts a reaction force on the water.
Is the speed of light greater or lesser in air than in water?
The speed is the same. Light travels at a finite speed.
The speed in water is less than or greater than the speed of sound of air?
The speed of sound in water is greater than the speed of sound in air . For example, at 20 °C and 1 ATM pressure, the speed of sound in air is 343 m/s, and its speed in water is 1482 m/s. In general, the speed of sound in a medium = (bulk modulus of the medium/ its density)^0.5 where the bulk modulus indicates how compressible the medium is; the greater the bulk modulus, the more incompressible the medium is. So, although water has a density much greater than that of air, water is also much more incompressible than air. When you solve for the speed of sound for both water and air using the above formula, you will find that it is greater in water.
A swimmer moves through the water at an average speed of 0.22 meter per second.The average drag force is 110 N.What average power is required of the swimmer?
Since the speed is constant (acceleration is zero), we know the horizontal forces are balanced.The swimmer's forward force cancels the 110N drag force.Work done by the swimmer is (110N x .22meter) = 24.2 N-m per second= 24.2 Joules per second= 24.2 watts
