Two small charged spheres are 6.52 cm apart. they are moved, and the force each exerts on the other is found to have tripled. ho

densk [106]

So all that really matters is the radius and how it changes, which is by a fact or of √3 and ∴ 6.52/√3 = 3.76cm which is the answer

Please show work and tell me how you did it.

Ilya [14]

Explanation:

1) speed of bicycle = $\frac{distance}{time}$

speed of bicycle= $\frac{20}{2}$

speed of bicycle = 10 miles/hour

2)speed of rocket = $\frac{distance}{time}$

speed of rocket= $\frac{9000}{12.12}$

speed of rocket= 742.57 meter/second

3)speed of jet plane = $\frac{distance}{time}$

speed of jet plane= $\frac{528}{4}$

speed of jet plane= 132 meter/second

4)speed = $\frac{distance}{time}$

time = $\frac{distance}{speed}$

time of trip= $\frac{350}{80}$

time of trip = 4.375 hour

5) Distance = speed × time

Distance = 6 × 3 × 60

Distance = 1080 meter

6) Average speed = $\frac{total distance}{total time}$

Average speed = $\frac{816}{10}$

Average speed = 81.6 km/hour

7) Time = $\frac{Distance}{speed}$

Time = $\frac{450 \times 1000}{120}$

Time = 3750 m/s
