In a series circuit, an ammeter shows that the current leaving the positive end of a cell is 0.5 A. What current flows into the negative end of the cell?

Compare the horizontal displacement of the two balls as they travel to the ground. what do you observe?

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 electric field inside a cell membrane is 8.0mn/c. what's the force on a singly charged ion in this field?
