Match the process with the fundamental interaction responsible for this process. - Protons in a nucleus repel each other. -The Earth pulls on the Moon. -Protons and neutrons attract each other in a nucleus. -A neutron outside a nucleus decays into a proton, electron, and antineutrino. with these : 1- The electromagnetic interaction 2- the gravitational interaction 3- The weak interaction 4- The strong interaction

1- The electromagnetic interaction - A neutron outside a nucleus decays into a proton, electron, and antineutrino

2- the gravitational interaction - The Earth pulls on the Moon

3- The weak interaction - Protons and neutrons attract each other in a nucleus

4- The strong interaction - Protons in a nucleus repel each other.

Wave speed = Wavelength x Frequency

26 m/s = Wavelength x 49

Divide by 49 to find the wavelength:

The wavelength is approximately 0.53
