Astronauts in space move a toolbox from its initial position →=<15,14,−8>m to its final position →=<17,14,−1>m. The two astronauts each push on the box with a constant force. Astronaut 1 exerts a force 1→=<18,7,−12> and astronaut 2 exerts a force 2→=<16,−10,16>. Required:
What is the total work performed on the toolbox?

Which is not a step in the rock cycle?

What is the name for the remnant of an asymptotic giant that has lost its shells? black dwarf white dwarf yellow giant black hole

Global warming will produce rising sea levels partly due to melting ice caps but also due to the expansion of water as average ocean temperatures rise. to get some idea of the size of this effect, calculate the change in length (in m) of a column of water 1.45 km high for a temperature increase of 1.12°c. assume the column is not free to expand sideways. as a model of the ocean, that is a reasonable approximation, as only parts of the ocean very close to
