A straight wire 50cm long conducts a 6.0 A current directed up out is the page. If the wire experiences a forever of 0.24N to the right die to a magnetic field perpendicular to its length, what is the magnitude and direction of the magnetic field

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) ! : )
