What is the force of attraction between marvin (mass 50kg$ and his dog commander k-9 (mass 30kg) when they are 3 meters apart? why is the five so small?

((6.7*10^-11)*(50kg)(30kg))/(5m^2) I don’t got a calculator but there them numbers it’s like Newton’s gravitational equation or sum like that

When seismic waves hit a fault, the waves are reflected off the fault. seismograph can detect these reflected seismic waves. geologists then use these data to map the fault's length and depth
