An iron ball and an aluminum ball of mass 100 g each are heated to the same temperature and then cooled to a temperature of 20°c. the heat lost by the iron ball is 3.6 kj. the heat lost by the aluminum ball is 7.2 kj. what does this imply?
a) the specific heat of iron is greater.
b) the specific heat of aluminum is greater.
c) the iron ball was heated to a higher temperature.
d) the aluminum ball was heated to a higher temperature.

The mini-refrigerator fire was most likely caused by what type of wiring?

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.

Organelles are 1. responsible for producing power for the cell 2. tiny structures in the cell that carry out the cell's activities 3. responsible for digestion in the cell 4. found outside of the membrane
