Answer:
a. 6.5 × 10⁴ mmHg
b. 5.9 × 10⁻⁴ atm
c. 1.0 × 10⁵ Pa
d. 0.97 atm
Explanation:
Transformaremos las siguientes unidades utilizando factores de conversión.
a. 85 atm a mmHg
Usaremos el factor de conversion 1 atm = 760 mmHg.
85 atm × 760 mmHg/1 atm = 6.5 × 10⁴ mmHg
b. 60 Pa a atm
Usaremos el factor de conversion 1 atm = 101325 Pa.
60 Pa × 1 atm/101325 Pa = 5.9 × 10⁻⁴ atm
c. 780 mmHg a Pa
Usaremos el factor de conversion 760 mmHg = 101325 Pa.
780 mmHg × 101325 Pa/760 mmHg = 1.0 × 10⁵ Pa
d. 740 mmHg a atm
Usaremos el factor de conversion 1 atm = 760 mmHg.
740 mmHg × 1 atm/760 mmHg = 0.97 atm
Complete question is;
What is the electrical potential at the surface of gold nucleus? The radius of a gold atom is 6.6 × 10^(-5) m and atomic number z = 79.
Answer:
172.36 × 10^(-5) V
Explanation:
We are given;
Radius; r = 6.6 × 10^(-5) m
Atomic number; Z = 79
Formula for Electric potential here is;
V = kZe/r
Where;
e is charge on proton = 1.6 × 10^(-19) C
k has a constant value of 9 × 10^(9) N⋅m²/C²,
Thus;
V = (79 × 1.6 × 10^(-19) × 9 × 10^(9))/(6.6 × 10^(-5))
V = 172.36 × 10^(-5) V
This is a question about converting energy from one form to another.
<span>While it is sitting on the ledge, it isn't moving, so at that point it doesn't have any kinetic energy. What it has is gravitational potential energy due to its height above the ground. </span>
<span>Just as it lands, it's at ground level, so it doesn't have any gravitational potential energy anymore. </span>
<span>The reason is that on the way down, it sped up, so all its original gravitational potential energy was turned into kinetic energy. </span>
<span>So if you can work out how much potential energy it had to start with, you will know that that is how much kinetic energy it ended up with just before it landed. </span>
<span>potential energy = m * g * h </span>
<span>where m is the mass, g is the acceleration due to gravity and h is the height </span>
potential energy = 4.45 * 9.81 * 0.800 = 35.3 J
