Consider three straight infinitely long (parallel to each other), equally spaced wires (with distance d), each carrying a current i in the same direction.
assume the three wires are coplanar. (eg. they are lying on the x, y plane where z = 0) , if the middle wire is rigidly displaced a very small distance x (x < < d) upward(in the z direction) while the other two wires are held fixed. analyze and describe the resulting motion of the middle wire. be specific in terms of magnetic field and gravity.

An object with initial temperature 130 ∘ f is submerged in large tank of water whose temperature is 50 ∘ f . find a formula for f ( t ) , the temperature of the object after t minutes, if the cooling constant is k = − 0.2 . remember newton's law of cooling (the rate of change of temperature with respect to time is equal to k times the difference between the temperature of the object and the surrounding temperature) ! : )
