Imagine that you have a selenium driver object (driver), on a page that contains several buttons. And you are in search of a specific button, but none of the Button web elements have a class or id to search by. Which of the following would return a list of all the Button web elements so you can check individually?

A valve on a storage tank is opened for 4 hours to release a chemical in a manufacturing process. The flow rate R (in liters per hour) at time t (in hours) is given by the linear model . Write the linear model in exponential form. Round the coefficients in equation to four decimal places.

A 1.5 kg1.5\, \text{kg} block is pressed against a spring with spring constant 250 N/m250\, \text{N/m}, compressing it by 0.20 m0.20\, \text{m}. The block is then released and slides across a horizontal frictionless surface. (a) How much potential energy is stored in the spring?(b) What is the block’s speed after leaving the spring?(c) If the block then enters a rough patch with coefficient of kinetic friction μk=0.15\mu_k = 0.15, how far does it travel before stopping?
