Water is flowing through a pipe of inner diameter 1.6 cm and length 12 m at a speed of 4.3 m/s. If the pipe is at a height of 5.2 m, what is the gravitational potential energy density of the water

*30 points + brainliest answer* gravity is pulling an object into the sun. the closer the object gets to the sun, the greater the gravitational force that acts on the object, increasing its acceleration. a line graph plotting the speed of the object against time would have which shape? a: straight line of positive slope b: curved line that slopes upward c: curved line that slopes downward d: straight line of negative slope

In this lab you will use a cart and track to explore various aspects of motion. you will measure and record the time it takes the cart to travel certain distances, and then complete some calculations. in the space below, write a scientific question that you will answer by doing this experiment.

In a real system of levers, wheels, or pulleys, the ama is less than the ima because the resistance force is greater than the effort force the effort force is greater than the resistance force some of the effort force must do work against friction the work input is dependent on the work output
