Jackson, being a Jets fan and trying to get away from this season, runs against the wind at a velocity of 2.0 m/s for 4.0 s and then turns around to save other Jets fans and runs with the wind at his back at 4.0 m/s for 4.0 s. Use positive values for against the wind and negative values for with the wind at his back. What is the average velocity of Brady during the 8 second time interval? *

The movement of electrons between atoms is called an

Aprotein molecule in an electrophoresis gel has a negative charge. the exact charge depends on the ph of the solution, but 30 excess electrons is typical. what is the magnitude of the electric force on a protein with this charge in a 1600n/c electric field? write in two significant numbers, and also in newton

Ineed this now one scientist feels that the changes in global climatic patterns may be good for the health of the biosphere. another scientist feels that sharp changes in climatic patterns could result in the extinction of the biosphere. which of these is the most likely reason the two scientists gave conflicting opinions on the impact of changes in the global climatic pattern? they do not have enough knowledge on the topic. they did not discuss the issue among themselves. they believe conflicting opinion strengthens science. they study different areas of science and have different scientific focuses.
