A tacheometer is setup at an intermediate point on a traverse course PQ and the following observations are made on a staff held vertical. Staff Station Vertical Angle Staff Intercept Axial Hair Readings P + 9o30′ 2.250 2.105 Q + 6o00′ 2.055 1.975 The constants are 100 and 0. Compute the length PQ and the reduced level of Q. RL of P = 350.50 m. Correct Answer 422.13 m; 335.47 m

Use D = Ks + C, where the constant K is equal to (f /i). It is called multiplying constant of the tacheometer and is generally kept as 100. The constant C is equal to (f + c). It is called an additive constant.

Stadia readings were taken with a theodolite on a vertical staff with the telescope inclined at an angle of depression of 3o30′. The staff readings were 2.990, 2.055 and 1.120. The reduced level of the staff station is 100.000m, and the height of the instrument is 1.40 m. What is the reduced level of the ground at the instrument? Take constants as 100 and zero.
Match the following, in the context of the leveling staff. a. Self-reading staff 1. The smallest division is 5 mm. its length is about 3 metres. b. Solid Staff 2. It has a moving target against which readings are taken by the staff man. The sliding target comes along with the vernier. c. Telescopic Staff 3. The readings are always taken from the telescope hence appear inverted. Therefore, readings are taken from downwards. d. Target staff 4. It has three telescopic lengths of 1.5, 1.5, and 2 meters when stretched out fully. Normally, its total length is 5 metres

Station 1, Station, 2 and station 3 are three towns on a river which flows uniformly. Station 2 is equidistant from station 1 and station 3. A man rows a boat from station 1 to station 2 and back in 17 hours. He can row from station 1 to station 3 in 7 hours. Find the ratio between the speed of boat in still water to the speed of flow of water?
The given bar graph represents both, theoretical and practical readings obtained in 5 rounds of readings while conducting a scientific experiment. What is the ratio of the difference obtained in readings 2 and 5 when calculated theoretically to the difference obtained in readings 1 and 3 when readings were taken practically?
Given below are four jumbled sentences. Pick the option that gives their correct order. A. According to hair loss experts, excess DHT drastically increases collagen production in the hair follicle. B. Hair loss can be traced to an increase of internal Dihydrotestosterone (DHT) and collagen production. C. Eventually, collagen blocks the pore completely causing a lack of necessary blood flow due to which your hair loses its sheen, thins down and finally you lose your hair completely. D. When too much collagen lines the interior of the follicle, it narrows the pores, decreases blood flow and slowly strangles your hair to death.
