Vi=15m/s
vf=20m/s
d=50m
a=(vf²-vi²)/2d
average acceleration= 1.75m/s
I believe L waves arrive last at a seismometer.
hope this helps!
E=hf C=wavelength*F
E=hC/wavelength
E=(6.626*10^-34)*(3.00*10^8)/670*10^-9
E=(6.626*10^-34)*(3.00*10^8)/450*10^-9
Are both intertwined. exercise and you will feel brand new!!!
