Answer:
a) El valor de la densidad es 0.79 
o 790
b) El peso especifico es 7749.9
Explanation:
a) La densidad se define como la propiedad que tiene la materia, ya sean sólidos, líquidos o gases, para comprimirse en un espacio determinado. En otras palabras, la densidad es una magnitud que permite medir la cantidad de masa que hay en determinado volumen de una sustancia. Entonces, la expresión para el cálculo de la densidad es el cociente entre la masa de un cuerpo y el volumen que ocupa:
En este caso:
- masa= 237 g= 0,237 kg (siendo 1000 g= 1 kg)
- volumen= 300 cm³= 0,0003 m³ (siendo 1 cm³= 0,000001 m³)
Reemplazando:
→ d=0.79
→ d=790
<u><em>El valor de la densidad es 0.79 </em></u><u><em> o 790 </em></u><u><em></em></u>
b) El peso específico es la relación existente entre el peso y el volumen que ocupa una sustancia en el espacio.
Entonces, en este caso, siendo el peso:
P= m*g= 0,237 kg* 9,81 
= 2,32497 N
el peso especifico es calculado como:
Pe= 7749.9
<u><em>El peso especifico es 7749.9</em></u><u><em></em></u>
Answer:
Nucleus A with 7 protons and 7 neutrons and Nucleus C with 7 protons and 5 neutrons are isotopes of the same elements
Explanation:
Isotopes are elements that have the same atomic structure but different molecular structure. An atom that has the same atomic number but different mass number are known to be isotopes.
The proton of an atom is the same as its atomic number while the sum of the proton and neutron is equal to its mass number.
According to the question, nuclei that has the same number of proton are isotopes of the same element. Therefore nuclei A and C with 7 protons each are isotopes of the same element since they have the same atomic number i.e number of proton = atomic number.
Their atomic masses of nuclei A and C are 14 and 12 respectively
Answer:
The correct answer would be downwards
Hope this helps have a good day
The impact would be great it would possibly freeze the work or melt the polar ice caps and flood the world to were we would invent technology light years away.
Core
Home of atoms of hydrogen also the lightest element in the universe.
Radiative Zone
Outside the inner Core it radiates energy through the process of photon emission.
Convection Layer
Outer most Layer of the Core, it extends form a depth of 200,000 kilometres to the visible surface. Energy is created by Convection. This is where light is produced.
Photosphere
Surrounds the stars and is where light and heat radiate.
Chromosphere
Reddish gas layer outside of the photosphere I think it also works with the Corona.
Corona
Aura of Plasma that surrounds the Sun and other stars, it extends millions of kilometres and easily seen during a total eclipse.
