Which atomic model was proposed as a result of j. j. thomson’s work?

What is the weight of a feather (mass = 0.0001 kg) that floats through earth's and the moon's atmospheres?

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) ! : )
