Which one of the following Remote Sensing Systems employs only one detector?

The maximum superelevation to be provided on a road curve is 1 in 15. If the rate of change of superelevation is specified as 1 in 120 and the road width is 10m, then the minimum length of the transition curve on each end(rotation of the pavement about the edge) will be

A four- lane divided highway, with each carriageway being 7.0m wide, is to be constructed in a zone of high rainfall. In this stretch, the highway has a longitudinal slope of 3% and is provided a camber of 2%. What is the hydraulic gradient on this highway in this stretch?

In an area of heavy rainfall, a State Highway of high-type bituminous surface with four lanes (14.0 m wide) is to be constructed. What will be the height of the crown of the road relative to the edges for a composite camber (i.e. middle half as parabolic and the rest as straight lines)?

Consider the following statements: 1). Effective stress in a sand layer below a lake with standing water does not alter as the water level fluctuates.2). Regarding the water table below the ground surface, any rise in the water table causes equal amount of changes in both pore pressure and total stress. 3). Capillary saturation will cause effective stress to increase. Which of these statements are correct?

A descending gradient of 4% meets an ascending grade of 1 in 40 where a valley curve of length 200 m is to be formed. What will be the distance of the lowest point on the valley curve from its first tangent point?
