The sum of the resistance = 2 ohms x 80 lights = 160 ohms.
Current = Total voltage / total resistance:
Current = 120V / 160 ohms
Current = 0.75 Amps
Distance = (speed) x (time)
Distance = (0.5 m/s) x (2.3 s)
Distance = (0.5 x 2.3) m
Distance = 1.15 meters
Answer:
<h2>The period is 0.04 sec</h2>
Explanation:
This problem is based on oscillatory motion.
What is the period of oscillation?
This can be defined as the time taken to complete one full revolution or oscillation.
given that the fly flaps its wings back and forth 25 times in one second. then the frequency is 25 Hz
we know that period T= 1/F
T= 1/25
T=0.04 sec
