1/A ball is dropped from the top of a building. After 3 seconds, its speed is measured to be 29.4 m/s. Calculate the acceleration of the dropped ball. 2/ How fast will the ball be going after 4 seconds?

heat the gas and measure the pressure

so easy. just google the electromagnetic waves and it’ll pop up.

i don't understand. explain it clearly

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
