<span>To answer this question with specific values, you would need a phase diagram for the substance in question. In more general terms, the pressure needs to be lower than the pressure of the triple point, the substance must be present in its solid state, and the temperature must rise high enough to produce a gas.</span>
Answer:
A. both fields use the same technology
Explanation:
Answer:
θ = cos^(-1) (-A/B)
Explanation:
The image of the reauktant forces A & B are missing, so i have attached it.
Now, from the attached image, we will see that;
Angle between A and B is θ
Also;
A = Bcos(180° − θ)
Now, in trigonometry, we know that;
cos(180° − θ) = -cosθ
Thus;
A = -Bcosθ
cosθ = -A/B
Thus;
θ = cos^(-1) (-A/B)
The work done by Nick as he raises the given mass over the given distance is approximately 2 Joules.
Given the data in the question:
- Mass raised;

- Distance covered;

Work done; 
First we calculate the force used to raise the mass to the given distance.
Since the movement was vertical, the force must over come the mass and the pull of gravity (
).
Using Newton's second law of Motion;

We substitute our values into the equation

Now, we determine the work done by Nick.
Work done is simply the energy transferred from one store to another.
It is expressed as;

So we substitute our values into the equation

Therefore, the work done by Nick as he raises the given mass over the given distance is approximately 2 Joules.
