The diagram shows the electric field in the vicinity of a charge. One positive charge labeled Y. Vectors start perpendicular to the surface and spread out in all directions. Directly above is W. On the right is X and on the left is Z. The vectors are closer together below the charge and further apart above.

At which point is the electric field strongest?

W
X
Y
Z

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) ! : )
