3. The gravitational force between two objects (mass1 = 8 kg, mass2 = 4 kg) is measured when the objects are 10 centimeters apart. If the 8 kg mass is replaced with a 4 kg mass and the 4 kg mass is replaced with a 8 kg mass, how does the new gravitational attraction compare to the first one that was measured?

Select the correct answer from each drop-down menu. compared to its surroundings, the concentration of solutes is low inside a cell. so, the cell is with respect to its surroundings. a particular solute in this cell uses energy for its transport from the cell to its surroundings. this type of transport is called

Calculate the amount of heat produced when 18000 coulombs of charge is transferred in one hour through a potential difference of 50v

In a system, when potential energy decreases, then entropy also decreases. true false
