Why is it important that the cell is semi-permeable? The most important thing about membranes is that they regulate what moves in and out of a cell. The membrane is selectively permeable because substances do not cross it indiscriminately. Some molecules, such as hydrocarbons and oxygen can cross the membrane. What are semipermeable examples? An […]

Does rotation of the Earth affect bullet?
Does rotation of the Earth affect bullet? Ballistic trajectories The Coriolis force minutely changes the trajectory of a bullet, affecting accuracy at extremely long distances. It is adjusted for by accurate long-distance shooters, such as snipers. Why do snipers have spotters? The spotter helps to closely observe the targets and their surroundings. The sniper fires […]

What is a comfortable wave period?
What is a comfortable wave period? Re: Wave height / Period /Wind speed comfort I’ve always felt that a wave period (in seconds) of 1.33 times the wave height (in feet) generally provides a comfortable ride. A wave period equal to, or less than, wave height (square waves) will be very uncomfortable. What is a […]
