Answer:
Charge on the red box is -0.0033 C as it is attracting the blue box
Explanation:
As we know that two boxes are attracting each other
So here we can say that two boxes will have opposite charges
So as we know that electrostatic force between two charges is given as
here we have
here we know that
r = 4 m
F = 626 N
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
