Para cambiar de lugar un escritorio de acero de 56kg, este se desliza sobre el piso de concreto aplicándole una fuerza de 159N, inclinada 35°. ¿Cuál es la magnitud de la aceleración que experimenta el escritorio, si se produce una fuerza de fricción de 56N entre el escritorio y el piso?

a electromagnetic waves

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.

d. platinum would have the greatest temperature increase because it has the lowest specific heat.

b. a lightning bug, plug of grass, and a worm
