Which statement correctly compares the uses of bar graphs versus circle graphs? 1) Bar graphs show data involved in distinct categories that do not overlap; whereas, circle graphs show patterns in data with variables that change over time. 2) Bar graphs show data involved in distinct categories that do not overlap; whereas, circle graphs show data as parts out of a whole (such as out of 100%). 3) Bar graphs show data as parts out of a whole (such as out of 100%) within a category; whereas, circle graphs show data having two or more different categories. 4) Bar graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).

Follow the steps provided in the simulation to add water to the graduated cylinder, select one of the three samples (copper, silver, or gold), set its mass to the values given in the statements below, and calculate its density. here is a summary of the steps required: add water by clicking and holding prepare a known volume of water button. until the desired volume of water has been added. if more than the desired volume is added, click the reset button. button and redo the procedure. a single click will add about 21.0 ml of water. to set the mass, click and hold weigh out metal button. until the desired amount of metal is added to the weighing pan. once the desired mass of the metal is added, release the button. transfer the metal to water and then click on calculate density button. to see how the density is calculated using water displacement to measure the volume of the solid. to save time you can approximate the initial volume of water to â±1 ml and the initial mass of the solid to â±1 g. for example, if you are asked to add 23 ml of water, add between 22 ml and 24 ml. which metals in each of the following sets will have equal density? check all that apply.

Most materials are not magnetic because their magnetism has worn off. their magnetic domains are arranged randomly. they lack magnetic fields. earth’s heat has destroyed their magnetism.

How are isotopes of the same element alike?
