Answer:
D. 539,000 J
Explanation:
The formula for potential energy(P.E) =mgh where m is mass of object, g is gravity acceleration 9.8 m/s² and h is height in meters.
From the question ;
m=500 kg
g= 9.8 m/s²
h= 110 m
P.E = mgh
= 500*9.8*110
=539,000 J
Answer option D
The other options are incorrect because the calculated values for the potential energy of the train are not equal to 539,000 J.

Answer:
The dependent variable is MEDV - Median value of owner-occupied homes in $1000's
Explanation:
The median value of the house has to be predicted, based on its properties and neighborhood properties, this can be done by using a linear regression model.
The dependent variable in Machine Learning is the output variable that we want to predict.
Therefore, according to the question given "MEDV" is the dependent variable.
I think it’s is false I’m not that sure
Answer:
When you build a compressor that is supposed to run in an enclosed system you want the coolant medium (and the lubricants) in this system to function optimally during the service life of the system.
First of all, the coolant medium has a tendency to absorb water and this moisture can be aggressive on the internal components of the compressor so you want to remove this once the system is sealed.
Second, you want to filter out any particles that may shorten the life of the system.
Those are the two purposes of the liquid line filter drier in the refrigeration system.
