I think the answer is B but not too sure.
(a) The velocity ratio of the screw is 1570.8.
(b) The mechanical advantage of the screw is 785.39.
<h3>
Velocity ratio of the screw</h3>
The velocity ratio of the screw is calculated as follows;
V.R = 2πr/P
where;
- P is the pitch = 1/10 cm = 0.1 cm = 0.001 m
- r is radius = 25 cm = 0.25 m
V.R = (2π x 0.25)/(0.001)
V.R = 1570.8
<h3>Mechanical advantage of the screw</h3>
E = MA/VR x 100%
0.5 = MA/1570.8
MA = 785.39

Marine debris is any trash or litter that ends up in a marine environment. This harms wildlife through entanglement, ingestion, and disturbs the habitat of many species of animals. This becomes a global problem when it is a danger to human health. Nails, syringes, and glass can cause harm to people on the beach. On top of that, trash in the waterway increases the amount of chemicals destroying our water quality.

The units which would need to be converted before being used for a calculation are cm and 0 ks.
<h3>
What is Unit?</h3>
This is referred to a standard which is used to make comparisons in the aspect of measurement.
The units cm and 0 ks aren't in their standard form which is m and s respectively.

Answer:
d. There is no way of knowing the phase composition without more information.
Explanation:
There is no way to ascertain the phases present in the container when equilibrium is established because we are not furnished with enough information.
- The most important information needed to have a deeper understanding and provide solution is temperature.
- Liquid water and ice can both exist at the same temperature.
- So we cannot conclude based on the information at hand.
