Answer:
The possible frequency of guitar are 842 HZ and 892 HZ.
Explanation:
given the beat frequency = = 25 HZ
we know that beat frequency = difference of frequencies of two instruments
therfore 25 = x-867 or 25 = 867-x
therefore x = 842 or 892

Proton: Its electrical charge is +1, its mass is 1, it's found in the nucleus
Neutron: Its electrical charge is 0, its mass is 1, it's found in the nucleus
Electron: Its electrical charge is -1, its mass is negligible, it's found outside the nucleus
Explanation:
Atoms consist of three types of particles:
- Proton: the proton is found in the nucleus of the atom, and it has a positive electric charge, equal to
(expressed in units of fundamental charge, it has a charge of +1). Its mass is
, while its mass expressed in atomic mass units is 1 a.m.u
- Neutron: the neutron is also found in the nucleus of the atom, and it has no electric charge. Its mass is similar to the mass of the proton (slightly larger), and neutrons and protons are held together in the nucleus by the presence of the strong nuclear force
- Electron: the electron orbits around the nucleus, far away from it. It has negative electric charge, opposite to that of the proton (
, or -1 in units of fundamental charge). Its mass is much lower than that of the proton, approximately 1800 times smaller, so it can be considered as negligible.
