(e) a high-speed electron in space far from all material objects, and free of electric and magnetic fields. (d) a car moving with a constant velocity of 30 km/h on a rough road (c) a kite skillfully held stationary in the sky (b) a cork of mass 10 g floating on water (a) a drop of rain falling down with a constant speed Q:- Give the magnitude and direction of the net force acting on.What is the direction in which she should hold her umbrella? A woman rides a bicycle with a speed of 10 m s –1 in the north to south direction. Rain is falling vertically with a speed of 30 m s –1. What is the percentage error in the quantity P ? If the value of P calculated using the above relation turns out to be 3.763, to what value should you round off the result ?įill in the blanks by suitable conversion of units: The percentage errors of measurement in a, b, c and d are 1%, 3%, 4% and 2%, respectively. The Chronos differenceĬontact our team today for specialist advice, support and more information.State the number of significant figures in the following:Ī physical quantity P is related to four observables a, b, c and d as follows : A three-decade legacy of reliability makes them the preferred choice in the critical time or frequency systems found in telecommunications timing, calibration and metrology laboratories, satellite tracking stations and spaced-based master time standards. Their Cesium instruments are built to provide stand-alone dependability, ease of use, and ease of installation. The 5071A Standard Performance comes standard with a 2-year electronics warranty and 10-year tube warranty.Ĭesium beam frequency and time standard instruments from our partner Microchip meet the most stringent requirements demanded by commercial, military and space applications. The 5071A has demonstrated an average mean time between failures (MTBF) of greater than 160,000 hours since its introduction in 1992. An internal battery provides 45 minutes of backup in case of AC power failure. All controls are programmable, status can be checked remotely, and no adjustments or alignments are necessary during operation. The 5071A can be operated and maintained anywhere. A logical menu structure simplifies front-panel operations, selections, and status reporting. Easy to use with Automatic Start-up and Intuitive Menu StructureĪutomatic start-up is simple and requires no adjustments. The 5071A is the first cesium standard to specify stability for averaging times longer than 100,000 seconds (approximately one day). The 5071A option 001 high-performance cesium beam tube guarantees stability to be better than 1 part in 10-14 for averaging times of five days or greater. Long-Term Stability Better than 1 x 10-14

This is achieved under full environmental conditions in 30 minutes or less, and without the need for any adjustments or alignments. The intrinsic accuracy of the cesium beam tube assures that any 5071A option 001 will power up to within 5 x 10-13 of the accepted standard for frequency. Key Features Frequency Accuracy to 5 x 10-13 Combined with a GNSS timing receiver, the 5071A primary frequency standard can produce a highly robust, inexpensive, and redundant frequency and time system. Thanks to a stability specification for 30-day averaging time, the 5071A can keep extremely predictable time and phase for long periods. Delivering Exceptional Frequency StabilityĮasy to use, the 5071A delivers exceptional frequency stability.
Used with GNSS systems, the 5071A provides master clock integration for telecommunication, satellite communication, and navigation systems. Product Information Unsurpassed Accuracy, Stability and Reliability for Demanding Laboratory and Field ApplicationsĪccurate, stable, and capable of delivering extremely predictable time and phase for long periods, the Microchip 5071A Cesium Clock Primary Frequency Standard meets the needs of leading-edge metrology and calibration labs.
