Difference of Pulsed Radar Vs CW Radar. Pulse Radar is use for detecting of target location. and CW Radar stands for continuous wave radar.Here is difference between Pulsed RADAR and CW RADAR.Pulsed RADAR :In this system the pulse modulated signal are USED for transmission.Duplexer is used to use common ANTENNA for transmission & reception.It can indicate the range of target.The echo power received is useful for the indicating device.It requires comparatively higher transmitting power.The circuits used in this system are comparatively complicated.The performance is sometimes affected by the stationary targets.It can not operate down to zero range.The possible r.max is higher.The performance is not affected by presence of number of targets.Practically pulsed RADAR system are used more.One example of such RADAR application is the mapping of airport area.CW RADAR :This system USES modulated or unmodulated continuous SIGNALS for transmission.Circulator is used or separate antennas are used for transmission & reception. SIMPLE CW RADAR can not indicate the range.The doppler frequency shift of echo signal is useful for indication device.It uses lower transmitting power.The circuits are simpler.The performance is unaffected by stationary targets.Because the receiver is ON all times, it can operate down to zero range.The possible r.max is lower.The system gets confused by persence of large number of targets.CW RADAR are used in some application only, so comparatively have less application.Application is in aircraft navigation for speed measurement.

e density = WEIGHT in AIR / weight in air -weight in waterR.D = 80/80-64R.D = 80/16 R.D = 5now,density of WATER = 1 g/cm³so the OBJECT WOULD sink .i hope it helps..............

Simple Harmonic Motion. When the motion of an oscillator reduces DUE to an EXTERNAL force, the oscillator and its motion are damped. ... In the damped simple harmonic motion, the energy of the oscillator dissipates CONTINUOUSLY. But for smalldamping, the oscillations REMAIN approximately periodic.

end..I THINK ur QUESTION is INCOMPLETE???Then???? What is the PROBLEM??

Closed organ pipe:If the air is blown lightly at the open END of the closed organ pipe, then the air column vibrates in the fundamental mode. There is a node at the closed end and an antinode at the open end. If l is the length of the tube,l = λ1/4 or λ1 = 4l               …... (1)If n1 is the fundamental frequency of the vibrations and v is the velocity of sound in air, thenn1 = v/λ1 = v/4l                  …... (2)If air is blown strongly at the open end, frequencies higher than fundamental frequency can be produced. They are called overtones. Fig.b & Fig.c SHOWS the mode of vibration with two or more nodes and antinodes.l = 3λ3/4     or λ3 = 4l/3              …... (3)Thus, n3 = v/λ3 = 3v/4l = 3n1      …... (4)This is the FIRST overtone or third harmonic.Similarly, N5 = 5v/4l = 5n1          …... (5)This is called as second overtone or fifth harmonic.Therefore the frequency of pth overtone is (2p + 1) n1 where n1 is the fundamental frequency. In a closed pipe, only odd harmonics are produced. The frequencies of harmonics are in the ratio of 1: 3:5HOPE IT HELPS MRK IT S BRAINLIEST

are good conductors of heat because of FOLLOWING two reasons : a) Metal ions are closely packed in the metal lattice and thus the transfer of heat from one END to another is more EFFICIENT. b) Availability of free ELECTRONS makes transfer of heat easier making it a good conductor of heat

d by an ELECTRIC charge free to move in an electric field or a mass free to move in a gravitational field, or generally any appropriate test particle in a GIVEN force field. More abstractly, lines of force are lines in any such force field the tangent of which at any point GIVES the field direction at that point and the density of which gives the magnitude of the field.  HOPE IT HELP U

ght that can be lifted by an effort of 100 N at longer SIDE will be 300 NExplanation :ratio of shorter arm: longer arm = 1 : 3=> LOAD arm : Effort arm = 1 : 3we know that ,LOAD/ Effort =  Effort arm : Load arm=> load/100 = 3 : 1=> load = 300 NHence the weight that can be lifted by an effort of 100 N at longer side will be 300 N

e the distance from point of 1st ACCIDENT to destination & S be speed of train.Case 1: D/S + 3/4 =D/(2S/3)On Solving we get,D/S=3/2Here, 3/4 is taken for 45min train stopped at the spot and train got late by 90 min so actual delay due to speed reduction is 90-45=45 mins.Case 2: 30 min have been saved cause of train travelling 60 KM more with speed S. So time difference if it would have travelled this 60 km with 2S/3 speed is nothing but the save of 30 min.So, 60/S - 60/(2S/3)= 1/2Solving S=60km/h.Now initially train travelled for 30 min before accident so distance travelled before accident = 60/2= 30km.And after accident it travelled D km.So from case 1, D/S=3/2===> D=90.So total distance = 30 +90=120 kms.

u are familiar with differential calculus.In order to get minimum time period differentiate time period w.r.t. ll and set it to 00 Also check second derivative to be positive. That should give you k=lk=l.Note that LOCUS of this will be a circle of radius kk and centre the centre of GRAVITY. Maybe your book is talking about a rod where there will be 22 points only as other points are not lying on it.For maximum time period : Clearly this will happen as lltends to 00 and time period tends to infinity.For points where time period is same: Simply put time period at length aa to be equal to that of length bb.You will get 22 SOLUTIONS: a=ba=b ork2=abk2=abAs we want different points, we will ignore the first solution. There will be again infinite points satisfying this condition on a general BODY. But your textbook MAY be talking of a rod where there will be 44 such points:a,−a,k2/a,−k2/aa,−a,k2/a,−k2/afor a general non-zero a lying on rod.

and SUNSET are the instants when the upper EDGE of the Sun appears and DISAPPEARS over the HORIZON respectively as a result of Earth's rotation. ... At a result, when sunlight passes through the atmosphere, successive refraction occurs and bends the sunlight towards the GROUND (see Figure 1).
