During normal beating, the heart creates a maximum 4.41 mV potential across 0.410 m of a person's chest, creating a 1.70 Hz electromagnetic wave. What is the maximum magnetic field strength in this wave

If you mix chlorine lithium in nickel together which two elements would be the most reactive

A33.1 g copper object is launched from a 1.5 m 30° steel incline positioned on the floor by being pulled up a string attached to a 50.0 g mass suspended vertically over a pulley. the object is projected towards a glass table where it lands when it is at the point along its trajectory with the lowest speed. it comes to a halt when it clears the opposite edge of the table. it then falls and lands on 9 physics texts each 5 cm thick that are stacked on the floor on the opposite side of the table. assume that the table does not have a ledge and the rectangular object experiences 0.05 n of air resistance as it falls towards the books. how far and how long did the object travel and how fast does it hit the books. assume that at the moment the copper object leaves the incline, the massless string and ideal pulley break off

An object moves from the position +34m to the position -15m in 15 seconds. what is it's total displacement? what is it's average velocity?
