Draw the vector starting at the black dot. the location, orientation, and length of the vector will be graded. you can move the vectors f⃗ 1 and f⃗ 2 to construct the required vector, but be sure to return them into their initial positions before submitting the answer.

While standing outdoors one evening, you are exposed to the following four types of electromagnetic radiation: yellow light from a sodium street lamp, radio waves from an am radio station, radio waves from an fm radio station, and microwaves from an antenna of a communications system. rank these type of waves in terms of increasing photon energy.

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 of a column of water 1.00 km high for a temperature increase of 1.00ºc. note that this calculation is only approximate because ocean warming is not uniform with depth. (answer in ×10^{-3} −3 m)

The energy released by a nuclear fusion reaction is produced when
