Por efecto del aumento de la temperatura, la roca se funde transformándose en magma. Si la temperatura al interior de la Tierra es tan elevada como para fundir roca, ¿por qué el suelo que pisamos no está a altas temperaturas?

Use the right-hand rule for magnetic force to determine the charge on the moving particle. this is a charge.

As a pendulum bob swings back and forth several times, the maximum height it reaches becomes less and less. this is because more and more of the pendulum bob's energy is being transformed into a. heat energy b. kinetic energy c. potential energy d. kinetic energy and potential energy
