Violent gas eruptions have been observed on mars, where the acceleration due to gravity is 3.7 m/s 2 . the jets throw sand and dust about 75.0 m above the surface. (a) what is the speed of the material just as it leaves the surface? (b) scientists estimate that the jets originate as high-pressure gas speeds through vents just underground at about 160 km/h . how much energy per kilogram of material is lost due to nonconservative forces as the high-speed matter forces its way to the surface and into the air?

i think the answer is a and b

i wish you luck

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .

find the surface area of the sphere to the nearest square unit. use a calculator.
