coulomb's law

f repulsive = q1q2/4 pi epsilon nought r squared

0.1= q1q2/4 pi epsilon nought 0.911 squared

q1+q2= 7.50 µC

0.1= q1(7.5µC-q1)/4 pi epsilon nought 0.911 squared

solve for q1

What happens to the appearance of an object as it gets hotter?
lana [24]

Answer:

Explanation:

When an object is heated then it becomes brighter and bluish compared to the initial condition. This happens because when an object is given heat then the electron in the ground state gets excited and reaches some higher state.

Except for the nodes on a standing wave, what is the frequency f of the points executing simple harmonic motion?
Katen [24]

Take into account that in a standing wave, the frequency f of the points executing simple harmonic motion, is simply a multiple of the fundamental harmonic fo, that is:

f = n·fo

where n is an integer and fo is the first harmonic or fundamental.

fo is given by the length L of a string, in the following way:

fo = v/λ = v/(L/2) = 2v/L

becasue in the fundamental harmonic, the length of th string coincides with one hal of the wavelength of the wave.
