Electric force is given by:
F = (kQ₁Q₂)/r²
where k is Coloumb's constant of value 9 x 10⁹, Q₁ and Q₂ are charges and r is the separation between them.
Let the charge of the nucleus be located at its center.
The separation of the proton is equal to:
Radius of nucleus + distance from surface
= 3 + 1.8
= 4.8 fm
Charge of Nucleus = 54e
Charge of proton = e
F = (9 x 10⁹ x 54 x 1.60 x 10⁻¹⁹ x 1.60 x 10⁻¹⁹)/(4.8 x 10⁻¹⁵)²
F = 540 N

Part 3)
The mass of the proton = 1.67 x 10⁻²⁹ kg
acceleration = 540/1.67 x 10⁻²⁹
= 3.20 x 10³¹ m/s²

The atmospheric pressure at 2000m altitude is 560. mmHg. What is the atmospheric pressure in atm? atm

Lostsunrise [7]

This problem is providing the atmospheric pressure at 2000 m altitude which is 560. mmHg and asks for this pressure in units of atmospheres, which after doing the calculations, the result is 0.737atm.

<h3>Atmospheric pressure:</h3><h3 />

In this case, we can firstly define the concept of atmospheric pressure, also known as barometric pressure, as that pressure exerted by a column of air over a specific point in space at a defined altitude.

<h3>Units conversion in pressure:</h3><h3 />

In order to get the correct conversion, we use the following equivalence statement relating mercury millimeters and atmospheres:

760 mmHg = 1 atm

Hence, the required conversion turns out to be:

$560.mmHg*\frac{1atm}{760mmHg}=0.737atm$
