Where is most of the mass of an atom located? A.in the nucleus B.in the orbits C.in the electrons Dit is split between the nucle
2 answers:
Answer:
A. In the nucleus
Explanation:
Atom mainly consisting of its three subatomic particles
1) Electron
2) Proton
3) Neutron
as we know that mass of electron is given as
mass of proton and neutron is approximately same and given by
now we know that mass of electron is 10000 times smaller than the mass of neutron and proton
so major part of mass of atom is due to proton and neutron
so its whole mass is concentrated in its nucleus
correct answer would be
A. In the nucleus

Answer:
El área de la placa es aproximadamente 5102.752 centímetros cuadrados.
Explanation:
Asumamos que el cambio dimensional como consecuencia de la temperatura es pequeña, entonces podemos estimar el área de la placa de cobre en función de la temperatura mediante la siguiente aproximación:
(1)
Donde:
- Ancho de la placa, en centímetros.
- Longitud de la placa, en centímetros.
- Coeficiente de dilatación, en
.
- Temperatura inicial, en grados Celsius.
- Temperatura final, en grados Celsius.
Si sabemos que ,
,
,
and
, entonces el área de la placa a la temperatura final:
El área de la placa es aproximadamente 5102.752 centímetros cuadrados.
The pressure exerted by the block on the table is given by:
where W is the weight of the box, and A is the bottom surface area of the box.
The weight of the box is:
Substituting into the first equation, we find the pressure:
