Can we convert mass to energy? First discovered by Einstein more than 100 years ago, it teaches us a number of important things. We can transform mass into pure energy, such as through nuclear fission, nuclear fusion, or matter-antimatter annihilation. Can mass be converted into energy or can mass be destroyed?

What are 4 reasons cells divide? Terms in this set (4) Food, Waste, and Gas Exchange. They need to maintain a workable ratio of surface area to volume to allow an efficient transfer of materials in and out of the cell. Growth. In order for an organism to grow, they must divide so they can […]

How long do coals burn for? about 1 hour Why do coals burn hotter? Coal and charcoal burn much closer to the source and keep the heat more concentrated leading to a higher temperature.

What four devices are used in measuring fault movements? Four instruments that are used to monitor faults are creep meters, laser-ranging devices, tiltmeters, and satellites. A creep meter uses a wire stretched across a fault to measure sideways movement of the ground. A laser-ranging device uses a laser beam bounced off a reflector to detect […]

Is it better to represent data in tabular form or in graph? Information: If the data that you have to be represented have numerical values, as well as details in text format, tables will represent it better. Charts do not have a way to represent text information without limitations. It can play with numbers to […]
