A 1.80-m section of a straight wire oriented along the z axis carries 13.5 A of current in the positive z direction. The wire is placed in a region with a uniform magnetic field of 4.40 T in the positive y direction. What are the magnitude and direction of the magnetic force on the wire

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) ! : )
