Answer:
number protons and force are Q = 1,472 10⁻¹⁷ C F = 3,656 10⁻⁸ N
Explanation:
Atoms are neutral whereby the number of electrons in the atom is compensated by an equal number of positively charged protons in the nucleus, so there are 92 protons, the total charge can be found by a rule of proportions
Q = # proton * 1.6 10⁻¹⁹C
Q = 92 * 1.6 10⁻¹⁹
Q = 1,472 10⁻¹⁷ C
To calculate the force of an electron we use Coulomb's law
F = k q1 Q / r²
F = k e Q / r²
The Coulomb constante is 8.99 10⁹ N m² /C²
F = 8.99 10⁹ 1.6 10⁻¹⁹ 1,472 10⁻¹⁷ / (7.61 10⁻¹⁰)²
F = 3,656 10⁻⁸ N
This force is attractive.
<span>Pollination is when the male gamete or pollen reaches the female flower through different modes...wind,air,animals,...
Fertilization </span><span>is when the male gamete "join" with the female gamete to become an embryo.
I hope I helped.:) </span>
Answer:
Option (2) : Sixteen times the first cube
Explanation:
Well it is due to the fact that when you
submerge
the wooden block into the cylinder. The displacement of water from the initial-measurement (before the block was submerge) to finial-measurement will be the volume of wooden block.
Note: In cases of floating objects. You can always add a sinker to it to submerge the object.
But
you will need to take into account the volume of the sinker and minus off the added volume of sinker.
