Answer:
Increase the distance by a factor of 6.
Explanation:
The intensity at a distance r is given by :
Here,
P is power emitted
r is distance from source
It means that the intensity is inversely proportional to the distance from the source.
To decrease the intensity of the sound you are hearing from your speaker system by a factor of 36, we can increase the distance by a factor of 6. Hence, this is the required solution.
<u>Explanation:</u>
s = ? u = 0m/s v = ? a = 5m/s² t = 2s
v = u + at
= 0 + (5 x 2)
= 10 m/s
s = ut + 1/2 at²
= (0)(2) + x x 5 x 2²
= 10 m

Answer:
r=15.53 nm
Explanation:
Lets take electron is in between iron and uranium
Charge on electron
Charge on iron
Charge on uranium
We know that force between two charge
For equilibrium force between electron and iron should be force between electron and uranium
Lets take distance between electron and uranium is r so distance between electron and iron will be 37.5-r nm
Now by balancing the force
So r=15.53 nm
So force
