A sound wave traveling in water 144m/s has a wavelength of 0.5m determine the frequency of the wave

Heya!!

For calculate frequency, lets applicate formula:

                                                   Δ   Being   Δ

                                               f = Frequency = ?

                                           v = Velocity = 144 m/s

                                          = Wavelenght = 0,5 m

⇒ Let's replace according the formula:

⇒ Resolving

Result:

The frequency of that wave is 288 Hertz

Good Luck!!

answer: the correct answer is 1.

explanation: there are various process in which a radioactive nuclei decays:

1) alpha decay: in this process, a heavier nuclei decays into lighter nuclei by releasing alpha particle. the mass number is reduced by 4 units.

2) electron capture: in this decay process, a parent nuclei absorbs an electron and gets converted into a neutron. simply, a proton and an electron combines together to form a neutron. mass number does not change in this process.

3) gamma ray emission: it is a decay process in which an unstable nuclei gives excess energy by a spontaneous electromagnetic process. this decay releases . this process does not change the mass number.

4) positron emission: it is a type of decay process, in which a proton gets converted to neutron and an electron neutrino. this is also known as -decay. in this the mass number remains same.

from the above information, we see that only alpha-decay is producing a change in the mass number of the nucleus.
