The formula $f = \frac{9}{5} c + 32$ can be used to convert temperatures between degrees fahrenheit ($f$) and degrees celsius ($c$). how many degrees are in the celsius equivalent of $-22^\circ f$?

Oxygen and hydrogen gas are at the same temperature t. what is the ratio of kinetic energies of oxygen molecule and hydrogen molecule if oxygen is 16 times heavier than hydrogen.

Engineers find a new metal that is stronger than steel but much lighter. this material is also significantly cheaper than what is currently used for most aircraft, available in large quantities, and easy to manufacture. the engineers are excited because this new material will lower the costs of buying and operating airplanes for companies. what is probably the best step for the engineers to make next?
