<em>Answer:</em>
- The atom consist of three parts, proton, neutron and electrons. The electrons determine that i will combine or beak from other substances.
<em>Explanation:</em>
The atom consist of three parts which are following
The proton and neutron form nucleus of an atom. It is present at center of an atom. They have positive charges, while electrons remained outside the nucleus in particular energy levels or shell around the nucleus.
During combination or breaking of substances ,only arrangements of electrons take place. The valence shell electrons decide whether they have to combine or not, while nucleus remained unchanged during any reactions.
Answer:
A = 356 cm²
Explanation:
In this case, you need to use the formula to calculate the area of regular solid.
This is the following expression:
S = 2LH + 2LW + 2WH
Where:
L: length
W: Width
H: Height
But we do not know the height of the solid. We should calculate it with the given data first:
1424 = 2*28*H + 2*28*16 + 2*16*H
1424 = 56H + 896 + 32H
1424 - 896 = 88H
H = 528/88
<em>H = 6 cm</em>
Now that we know the height we can calculate the area of the other solid. In the other solid the length has been reduced to half, so I will assume that the Width and height is also reduced to half.
L2 = 14 cm
W2 = 8 cm
H2 = 3 cm
Replacing we have:
S = (2*14*3) + (2*14*8) + (2*8*3)
<u>S = 356 cm²</u>
<u>And this should be the total surface area, assuming the width and height is reduced to half too.</u>
If you don't assume it's reduced to half, then use the original values of Width and Height. Doing so, the Surface would be:
S = (2*14*6) + (2*14*16) + (2*6*16)
S = 808 cm²
