Answer:
F/2
Explanation:
In the first case, the two charges are Q1 and Q2 and the distance between them is r. K is the Coulomb's constant
Hence;
F= KQ1Q2/r^2 ------(1)
Where the charge on Q1 is doubled and the distance separating the charges is also doubled;
F= K2Q1 Q2/(2r)^2
F2= 2KQ1Q2/4r^2 ----(2)
F2= F/2
Comparing (1) and (2)
The magnitude of force acting on each of the two particles is;
F= F/2
B IS YOUR ANSWER.
Soft sound has small amplitude and louder sound has large amplitude. Since, the second wave has large amplitude, it will have the loudest sound.
Answer:
In vector form , if angle between velocity vector and acceleration vector is less than 90° and greater than 0° then it is positive acceleration and if it is less than 180° and greater than 90° then it is negative acceleration. If there is no acceleration vector then it is called zero acceleration
Explanation:
Answer:
340 meters
Explanation:
For this we have to use the formula of constant velocity motion:
![d=v*t\\where:\\d=distance\\v=velocity\\t=time](https://tex.z-dn.net/?f=d%3Dv%2At%5C%5Cwhere%3A%5C%5Cd%3Ddistance%5C%5Cv%3Dvelocity%5C%5Ct%3Dtime)
Because you hear the blows exactly 1 per second. And you hear only one blow after she finished, the sound takes one second to get to you.
![d=340(m/s)*(1(s))=340m](https://tex.z-dn.net/?f=d%3D340%28m%2Fs%29%2A%281%28s%29%29%3D340m)
4.52•10^12 = 4520000000000
or?
4.52•10^12,000,000 = 452 with 12 million zeros minus 2 zeros at the end,
Because 4.52•10^12m doesn’t have a value added to it. But there are your valid answers anyways.
