Answer:
mass x gravity x height
Explanation:
Gravitational potential energy is measured in jules
Answer:
Silicon (2.33 g/cm3) < Titanium (4.51 g/cm3) < Nickel (8.9 g/cm³) < Copper (8.96 g/cm³)
Explanation:
Density of copper = 8.96 g/cm³
Density of Nickel = 8.9 g/cm³
Density of Titanium = 4.51 g/cm3
density of silicon = 2.33 g/cm3
The correct order of above metals based on the increasing density is as follow
Silicon (2.33 g/cm3) < Titanium (4.51 g/cm3) < Nickel (8.9 g/cm³) < Copper (8.96 g/cm³)
Thus, copper has the highest density among all.
From the definition of entropy, the entropy change of an object is

where
Q is the heat absorbed
T is the absolute temperature
in our problem, we have Q=25.0 J, while the absolute temperature is (converting in Kelvin)

and so the entropy change is
Interactúan dos objetos cargados dependiendo de la carga domínate en el objeto, ya que cargas iguales se repelen y cargas opuestas se atraen. ... Al frotar un cuerpo cargado con otro objeto de carga neutra, este se cargara pero adquiriendo la carga opuesta al objeto cargado inicialmente.
