Google Sheets, the spreadsheet tool that's part of the Google Apps productivity suite, lets users format cells based on certain conditions, including the date contained in a cell and how far away that date is from the present.
The Geiger counter, is an instrument used for measuring ionizing radiation used widely in such applications as radiation dosimetry, radiological protection, experimental physics and the nuclear industry.eiger counters are widely used to detect gamma radiation, and for this the windowless tube is used. However, efficiency is generally low due to the poor interaction of gamma rays compared with alpha and beta particles.
The radio telescope is used to detect most of the things that an optical telescope can not see. The comments of a radio telescope are the same as in a car radio. The both have the antenna, the receiver, the detector, and the computer or speaker. The radio telescope's dish has to be very large. The reason for this is that the radio telescope detects very weak signals. So it has to be big to do that. The dish of a radio telescope collects all the waves at the wave length that the receiver is tuned to.
