Answer:
The football leaves with the velocity, u = 15.68 m/s
Explanation:
Given data,
The football bounces back up off the ground and is airborne for, t = 3.2 s
Let the football bounces back up off the ground in the vertical direction
The formula for time of flight is given by,
t = 2u /g
∴ u = gt / 2
Substituting the values,
u = 9.8 x 3.2 / 2
u = 15.68 m/s
Hence, the football leaves with the velocity, u = 15.68 m/s
Answer:
V = 156.13 [cm³]
Explanation:
El volumen de un solido con forma de paralepipedo se puede calcular por medio de la siguiente formula:
donde:
V = volumen [cm³]
ancho = 3.4 [cm]
largo = 11.2 [cm]
alto = 4.1 [cm]
Ahora reemplazando.
![V = 3.4*11.2*4.1\\V = 156.13 [cm^{3}]](https://tex.z-dn.net/?f=V%20%3D%203.4%2A11.2%2A4.1%5C%5CV%20%3D%20156.13%20%5Bcm%5E%7B3%7D%5D)
Electrons can move from one atom to another.
When a lot of them are doing it at the same time,
you have an electric current.
We asked around here at Brainly, and nobody knows
what an "Msideus" is, but we all know that there aren't
any of them in atoms.
Answer: it becomes a positive ion
Explanation:
So, when an atom loses 2 electrons there will be no change in the number of neutrons. Therefore, an isotope will not form. Thus, it is concluded that when an atom with no charge loses two electrons, it becomes a positive ion.
Answer:
Rubber is an insulator.
Explanation:
Rubber is an insulator. Electricity will always travel "the path of least resistance." Rubber has a very high resistance, so electricity will go somewhere else to find ground.
