Physics Help

Order annual and semester physics tests for schoolchildren and students. We can help you solve problems in physics We provide help to schoolchildren and students from Russia, Belarus, Ukraine, Latvia in the discipline of “physics” and all related sciences. Why do you need to order solutions to physics problems? Because physics is an experimental science which hasn’t been studied completely because all its regularities and theoretical data are based on experiments which later fail to work under certain conditions.  You…

Problems on internal energy with solutions Physics problem #1. Scissors and a pencil lying on the table have the same temperature. Why do the scissors feel colder than the pencil? Problem Solution: A human hand under normal conditions has a higher temperature than the scissors and pencil. Therefore, when the hand comes in contact with these objects the heat exchange starts: the hand loses some heat, and the pencil and the scissors get it. But the thermal conductivity of wood,…
