First, we need to fight the weight of the balls instead of their mass. We do this by multiplying their weight it kg by 9.8. This gives us .98 N. To find the potential energy of the rolling ball, we find its kinetic energy. The formula for this is KE=mass*velocity^2*1/2.
Plugging in our numbers, we have Kinetic energy = .1 * 1^2*1/2 which gives us .05 joules.
Now we find the potential energy of the ball on the shelf. For this we do:
Potential energy = .1*9.8*1, and our answer is .98 joules. Clearly, the ball on the shelf has more energy.
Well, I'm not sure right now that it actually does.
But if it does, that's because the sun is about 400 times
FARTHER from the Earth than the moon is.
The sun is a yellow dwarf star, so the correct answer is yellow. Hope it helps! If you could vote me brainiest, that would be awesome!
Answer:
El material del calorímetro es aislante, conducción térmica entre sustancias y alrededores casi nula.
Explanation:
Es posible suponer que la energía térmica que gana el agua en un calórimetro equivale a la energía térmica perdida por la muestra que se prueba, en tanto que el material del calorímetro se caracteriza por ser de naturaleza aislante, es decir, que no permite las interacciones de energía entre los fluidos al interior y los alrededores del calorímetro.
