How do you calculate effusion? From Graham’s law, we can use the molar mass of each gas: rate of effusion of hydrogenrate of effusion of oxygen=√32g mol−1 √2g mol−1 =√16√1=41 rate of effusion of hydrogen rate of effusion of oxygen = 32 g mol − 1 2 g mol − 1 = 16 1 = […]
Do balloons hurt animals?
Do balloons hurt animals? Dolphins, whales, turtles, and many other marine species, as well as terrestrial animals such as cows, dogs, sheep, tortoises, birds and other animals have all been hurt or killed by balloons.

What materials amplify sound the best?
What materials amplify sound the best? A material’s elasticity or “springiness” is also important for transmitting sound: less elastic substances such as hard foams and paper are more likely to absorb sound than carry it. The best materials for carrying sound waves include some metals such as aluminum, and hard substances like diamond. What does […]

Does higher frequency mean higher speed?
Does higher frequency mean higher speed? The frequency of a signal voltage is measured in cycles per second. One hertz is one complete cycle per second. While higher frequency can mean a faster system, a truer measurement of communication speed is bit rate. Most data communications systems operate at millions of cycles per second, or […]

What do you expect to find in mid ocean ridge?
What do you expect to find in mid ocean ridge? Mid-ocean ridges occur along divergent plate boundaries, where new ocean floor is created as the Earth’s tectonic plates spread apart. As the plates separate, molten rock rises to the seafloor, producing enormous volcanic eruptions of basalt. What technology did scientists use in the mid 1900s […]
