Water wave traveling in a straight line on a lake is described by the equation y(x, t)=(2.75cm)cos(0.410rad/cmx+6.20rad /st) where y is the displacement perpendicular to the undisturbed surface of the lake.

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary 

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !
