WebThe density was measured employing the gravimetric buoyancy method. X-ray diffraction (XRD) patterns were obtained. Crystal domain size was estimated using the Scherrer equation from XRD diffraction peaks using the full width . at half maximum (FWHM) of the (111) peaks. Cross-sectional scanning electron microscopy (SEM) was performed at An instrument used to measure gravity is known as a gravimeter. For a small body, general relativity predicts gravitational effects indistinguishable from the effects of acceleration by the equivalence principle. Thus, gravimeters can be regarded as special-purpose accelerometers. Many weighing scales may be regarded as simple gravimeters. In one common form, a spring is used to coun…
