Answer:
E cinetica = 140.24 [J] "unidades en Joules"
Explanation:
Para poder solucionar este problema debemos tener un dato aproximado de la masa de la pelota de beisbol, ya que en el problema este dato no fue dado, realizamos una busqueda por internet y encontramos que la masa de una pelota de beisbol es de aproximadamente m = 142 [gr].
Datos iniciales:
m = masa = 0.142 [kg]
v = velocidad = 160 [km/h]
debemos convertir de kilómetros por hora a metros por segundo.
Sabemos que la energia cinetica se define por medio de la siguiente ecuacion:
Answer:
The lifetime of the particle is
Explanation:
From the question we are told that
The average rest energy is
The intrinsic width is
The lifetime is mathematically represented as
Where h is the Planck's constant with a value of
substituting values
The paper clip did because it is a conductor. A pencil is made with wood and that is an insulator.
I believe it’d have a higher resistance because if it had a lower resistance more electrons could travel threw it
