Britney has four different materials of different masses. She decides to test their electrical conductivity by connecting each in a closed electric circuit and then measuring the amount of current that passes through them. Her results are collected in the table below. Material Mass (g) Current (A) W 10.0 0.0 X 65.0 0.0 Y 23.5 4.0 Z 82.0 0.0 Which material is most likely a metal? A. X B. Y C. W D. Z

The diagram below shows a cell placed in a solution.a cell is shown placed inside a beaker. it is labeled cell. the solution inside the beaker is labeled 40% salt solution and the solution inside the cell is labeled 20% salt solution.only water is allowed to move in and out of the cell. what will most likely happen to the cell? it will expand as water moves out of it. it will shrink as water moves out of it.it will expand as water moves into it. it will shrink as water moves into it.
