Once every month a new moon is observed when earth and moon orbit the sun . during this period the moon experiences a net zero gravitational force . mass of sun is 1,99×10^30kg
mass of moon is 7,35×10^22kg
gravitational force of attraction between moon and earth is 1,997×10^20N. calculate the distance between the centres of the sun and moon during the new moon​

What are similarities and differences of reflection, refraction, diffraction and absorption?

Select light for the type of wave, adjust the wavelength so that the light is red, and increase the amplitude of the light to the max. then, select the start button at the source location to begin producing the waves. light is a form of electromagnetic wave, containing oscillating electric and magnetic fields. the wave amplitude detector mentioned above shows how the electric field oscillates in time at the location of the probe. the amplitude of the wave at the location of the probe is equal to the maximum electric field measured. how does the amplitude of the wave depend on the distance from the source?
