Question

5. Express each of the following in terms of
trigonometric ratios of angles, lying between 0°
and 45°:
(i) sin 58° + cos 53°
(ii) tan 63° + cot 59°
(iii) sec 74° + cosec 51°
(iv) cos 77° + sin 77°
(v) sin 720 + coser 540​

Answer 1

Answer:

Answer:

relative density of liquid

     = density of liquid / density of water

     = buoyancy force in liquid / buoyancy force in water

     = Loss of weight in liquid / loss of weight in water

     = [ weight of object  in air - weight of object in liquid ] / [ weight of object in air - weight of object in water ]

     = [ 75 - 70.5 ] / [ 75 - 66 ]

     = 4.5 / 9

     = 0.5

Density of liquid = 0.5 * density of water

             = 0.5 * 1000 kg / m^3

                 =  500 kg/m^3
