Gabriela is playing with her toy rattle, and decides to toss the rattle in the air at a 90 degree angle. The initial velocity of the rattle is +9 m/s 1.Kristy claims that the rattle would achieve a higher height if it were launched at a 62 degree angle. Is Kristy correct? Explain your answer.

2.What is the velocity of the rattle be when it returns to Gabriela? Explain how you know.

What are some properties of transverse waves?

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

Am i correct on these two physics questions?
