Answer:

[tex]\alpha=(1/120)*14*360=42[/tex]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

[tex]t_t= 1/120 seconds[/tex]

eel rotates

[tex]\alpha_1=14rev *360[/tex]degrees in 1 second

so:

eel rotetas [tex]\alpha=(1/120)*14*360=42[/tex]degrees
