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:
Explanation:
Resistance of the tungsten wire
R = resistivity x length / cross sectional area
=
= 107 x 10⁻⁴ ohm
Resistance at 120 degree can be obtained from the following formula
= 155.15 x 10⁻⁴ ohm
= 160 x 10⁻⁴ ohm ( rounding off to two syg fig )
current = 12.5
potential diff = 12.5 x 155.15 x 10⁻⁴ V
= 0 .1939 V
= .19 V
required electric field = potential diff / length of wire
= .1939 / 16 x 10⁻²
= 1.2 N / C
