A region where no magnetic field is desired is surrounded by a sheet of low-resistivity metal. Will this sheet shield the enterior froma rapidly changin gmagnetic field outside? Explain

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) ! : )

The particles that are found in the nucleus of an atom are
