An unstable isotope changes until it reaches a different element that is stable.
An unstable isotope changes until it reaches a different isotope of the same element that is stable.
i just did this on ed the other answer was wrong. these ones are right tho
Explanation:
acceleration equation is change in velocity/time
so 100/3 will be 33.3km
Answer:
Part(a): The required change in angular displacement will be .
Part(b): The angular displacement will be increased by a factor of 2.
Explanation:
If , , and represents the initial angular velocity, the final angular velocity , the angular acceleration and the change of angular displacement s, then from angular kinematic equation, we can write
Part(a):
Given, , and . Substituting ll the values in the above equation, we have
So the angle through which the parts rotates before reaching the final speed is .
Part(b):
Given, , and . So,
Therefore, the angular displacement will be changes by a factor of 2.
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.
