A car is driving 20.7 m/s when the passenger throws a ball from the window at 3.7 m/s in the same direction as the motion of the car. Ignoring air resistance, what is the speed of the ball (in m/s)? (Assume both given values are to the nearest 10th).

From the perspective of an employee that effective channeling of work related information and concerns

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

Answer fast for how does the force exerted by two magnets change as the magnets are moved farther apart? the magnetic force increases. the magnetic force decreases. the magnetic force stays the same.
