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:
How do you find out the missing masses in a balloon?
Well, actually you can't find the missing masses in a balloon. Why?
Because the mass of the mass of balloon, it can't see the mass of it, it only see if it the balloon is deflated or inflated.

Answer:
Explanation:
The bulk modulus is a constant that describes how resistant a substance is to compression.
It is defined as the ratio between increase in pressure and the resulting decrease in a volume of the material.
It is given by a formula :
OR
where:
& are the change in volume and change in pressure respectively.
V= original volume
According to the given:
So,
.................................(1)
&
..................................(2)
From the given conditions we compare equations (1) & (2):
cancelling the equal terms
The material in first case undergoes twice the volume reduction than that of the material in first case under the given conditions.
<h3><u>Answer;</u></h3>
4. the material the object is made of and the color of light that strikes it
<h3><u>Explanation;</u></h3>
- The color of an object is the wavelength of light that the object reflects, which is determined by the arrangement of electrons in the atoms of the material making the object.
- <em><u>We could therefore say that the color of object depends on or is determined by the material making up the object as this determines the the wavelengths of light the object reflects. Lastly, the color of light source also determines the color of the object.</u></em>
