G=mg=>m=G/g=16680/9.8=1702 kg
p=mv=>v=p/m=54400/1702=32 m/s
Answer:
Δt = 0.315s
Explanation:
To calculate the time difference, in which both fans hear the batterstrike, you first calculate the time which takes the sound to travel the distances to both fans:
d1: distance to the first fan = 18.3 m
d2: distance to the second fan = 127 m
vs: speed of sound = 345 m/s
You replace the values of the parameters to calculate t1 and t2:
The difference in time will be:
Hence, the time difference between hearing the sound at the location s of both fans is 0.315s

The resistance of the laser whose voltage difference pushes the current through its laser diode is 2 ohms.
<h3>What is resistance?</h3>
The resistance is the opposition offered to the current flow.
According to the ohm's law, potential difference is directly proportional to the current flowing in the conductor.
V =I x R
Where R is the constant of proportionality called resistance.
Given is the potential difference V =10 Volts and the current flow of 5A, then the resistance will be
R = 10/5 = 2 ohms.
Thus, the resistance of the laser is 2 ohms.
