If an object has a density of 10g/cm^3 and is taken to a planet where where the gravity is two times greater than earth, what will be the density of the new object on the new planet

The slope of a good speed time indicates ? a. velocity b. acceleration c. direction d. speed

F500 j of energy were added to 1 kg of each of these samples, which would experience the least temperature increase?

Three different objects, all with different masses, are initially at rest at the bottom of a set of steps. each step is of uniform height . the mass of each object is a multiple of the base mass : object 1 has mass 4..00m , object 2 has mass 1..96m , and object 3 has mass . when the objects are at the bottom of the steps, define the total gravitational potential energy of the three-object system to be zero. if the objects are then relocated as shown, what is the new total potential energy of the system? each answer requires the numerical coefficient to an algebraic expression. each algebraic expression is given using some combination of the variables , , and , where is the acceleration due to gravity. enter only the numerical coefficient. (example: if the answer is 1..23mgd , just enter 1.23)
