There are six distinct changes of phase which happens to different substances at different temperatures. ... Sublimation: the substance changes directly from a solid to a gas without going through the liquid phase. Deposition: the substance changes directly from a gas to a solid without going through the liquid phase.

Answer:
degrees
Explanation:
Eels have been recorded to spin at up to 14 revolutions per second when feeding in this way
So the angle the eel rotate is going to be
Camera record 120 frames per second
time taken for 1 frame record
eel rotates
degrees in 1 second
so:
eel rotetas degrees
Answer:
Object in motion: By the Newton's first law about inertia, an object in motion tends to keep in motion, unless an external force act on it.
Object at rest: By the Newton's first law about inertia, an object at rest tends to keep at rest, unless an external force act on it.
The hydrometer displays the density of the liquid you stick it in, COMPARED TO WATER.
If you stick it in pure water, it should read 1.00 . This is a good way to check your hydrometer and see whether it's reading correctly ("calibrated").

Total displacement 155 m
Explanation:
From the question, the formula to apply will be that of cosine rule where:
where
a= 43 m , b=130m and c =? , <C=28° + 90° =118°
Substituting values in the equation as;
