Distance = speed/time

width/distance given is 2.9*10^3 miles
1 mile=1.6*10^6mm
total distance now is 2.9*1.6*10^9
speed is 25 mm/yr
plug the values,

The force between two objects, each of charge +Q is measured as +F when the objects are separated a distance d apart. If the cha
dybincka [34]

Answer:

F'=4F

Explanation:

According to Coulomb's law, the magnitude of the force (F) between two  objects  with the same charge(+Q), separated a distance (d) apart, is defined as:

F=\frac{kQ^2}{d^2}

Here k is the Coulomb constant. The charge on each object is doubled, that is Q'=2Q:

F'=\frac{kQ'^2}{d^2}\\F'=\frac{k(2Q)^2}{d^2}\\F'=4\frac{kQ^2}{d^2}\\F'=4F

e-lub [12.9K]

Answer:

The frequency of the beats is 43.6408 kHz

Explanation:

Given:

f = frequency = 39.6 kHz

vc = speed of the car = 35 m/s

vs = speed of the sound = 343 m/s

Question: What is the frequency of the beats, f' = ?

As the car moves towards the source, the frequency of the beats

f'=f*(1+\frac{v_{c} }{v_{s} } )=39.6*(1+\frac{35}{343} )=43.6408kHz
