Suppose you adjust your garden hose nozzle for a hard stream of water. You point the nozzle vertically upward at a height of $1.5 m$ above the ground (the hose is $1.5 m$ off the ground). When you quickly move the nozzle from the vertical you hear the water striking the ground next to you for another $2.1 s$ .What is the water speed as it leaves the nozzle?

Why is gravitational force the weakest force in nature?

The majority of Physics equations are not overly complex since they are based on questions that are either related to some theory or focus on a specific experiment. You will find a plethora of answers that will help you understand the main concepts from college physics to more complex engineering tasks that are quite specific. If you are dealing with equations, the solutions will let you compare things to what you have and find an answer. There will also be questions that are more verbal in nature, meaning that they go beyond the formulas, so ensure to check them, too!
