PCl_5 has trigonal pyramidal geometry with sp^3 d hybridisation in gases and liquid state but in solid state it exist as ionic compound. The hyridisation of P and shape of POCl_3 are.

Arrange the following steps in a sequence of find the vlume oof an irregular shaped solid body. (A). The irregular shaped solid is tied with the thread and is lowered into the measuring cylinder. (B). A measuring cylinder with graduations in millilitre or cubic centimetrer is taken. (C). The level of water in the measuring cylinder rises after immersion of the solid. (say V_(2) ) (D) First, it is filled with water to a certain level or volume. (say V_(1) ) (E). The volume of the stone is equal to the difference between the volume of the water before and after the immersion of the stone. (V_(2)-V_(1)) .

Fluids at rest exert a normal force to the walls of the container or to the sruface of the Body immersed in the fluid. The pressure exerted by this force at a point inside the liqid is the sum of atmospheric pressure and a factor which depends on the density of the liquid, the acceleration due to gravity and the height of the liquid, above that point. The upthrust acting on a body immersed in a stationary liquid is the net force acting on the body in the upward direction. A number of phenomenon of liquids in motion can be explain by Bernoulli's theorem which relates the pressure, flow speed and height for flow of an ideal incompressible fluid. A container of large uniform corss sectional area. A resting on a horizontal surface holds two immiscible, non viscous and incompressile liquids of densities d and 2d , each of height H//2 as shown in the figure. The lower density liquid is open to the atmosphere having pressure P_(0) . Situation I: A homogeneous solid cylinder of length L(LltH//2) . cross sectional area A//5 is immersed such that it floats with its axis vertical at liquid -liquid interface with lenght L//4 in the denser liquid. The density of the solid is

A solid sphere of radius r is melted and cast into the shape of a solid cone of height r , the radius of the base of the cone is 2r (b) 3r (c) r (d) 4r

A scale drawing of an object is the same shape at the object but a different size. The scale of a drawing is a comparison of the length used on a drawing to the length it represents. The scale is written as a ratio. The ratio of two corresponding sides in similar figures is called the scale factor. Scale factor= length in image / corresponding length in object. If one shape can become another using revising, then the shapes are similar. Hence, two shapes are similar when one can become the other after a resize, flip, slide or turn. In the photograph below showing the side view of a train engine. Scale factor is 1:200. This means that a length of 1 cm on the photograph above corresponds to a length of 200cm or 2 m, of the actual engine. The scale can also be written as the ratio of two lengths. If two similar triangles have a scale factor 5:3 which statement regarding the two triangles is true?
