Answer:
Yes I think... But the joke is it is a walk then.
Hg vacuum at 20 inches is the saturation pressure that corresponds to 32 degrees Fahrenheit of R-123.
To find the answer, we need to know more about the saturation pressure.
<h3>
What is saturation pressure?</h3>
- The saturation pressure is the pressure at which a vapor is in equilibrium with its liquid (such as steam with water).
- It is the highest pressure that water vapor can get at a particular temperature.
- R-123 refrigerant is probably hard to find these days.
- It was discovered that chlorine-containing refrigerants have the potential to actively harm the Ozone layer if they are released into the atmosphere.
- The saturation pressure that corresponds to 32 degrees Fahrenheit of R-123 is 20 inches Hg vacuum.
Thus, we can conclude that, Hg vacuum at 20 inches is the saturation pressure that corresponds to 32 degrees Fahrenheit of R-123.

Answer:
The acceleration of the laundry cart is 13.3 m/s²
Explanation:
Hi there!
According to Newton's second law, the sum of all forces acting on an object in a given direction is equal to the mass of the object times its acceleration in that direction:
∑F = m · a
Where:
∑F = net force acting on the cart.
m = mass of the cart.
a = acceleration.
Then, solving this equation for the acceleration:
∑F / m = a
60.0 N / 4.50 kg = a
a = 13.3 m/s²
The acceleration of the laundry cart is 13.3 m/s²
