The young "s" modulus and rigidity modulus of a metal are "40" Gpa and "20" Gpa respectively.Then bulk modulus is (A) "13.33" Gpa (B) "26.67" Gpa (C) "6.67" Gpa (D) "120" Gpa

If the compressibility of water is 0.5GPa^(-1), then its bulk modulus is

 The volume change of a solid copper cube 10 cm on an edge, when subjected to a pressure of 7 MPa is (Bulk modulus of copper 140 GPa)

If a,b,c are in GP.a,x,b and b,y,c are both in A.P., the valuc of is (1)/(x)+(1)/(y) is

An elastic string of length 42 cm and cross section area 10^(-4) m^(2) is attached between two pegs at distance 6 mm as shown in the figure. A particle of mass m is kept at midpoint of string stretched as shown in figure by 20 cm and released. As th string attains natural length, the particle attains a speed of 20 m//s . Then young modulus Y of string is of order (A) 10^(@) (B) 10^(12) (C) 10^(8) (D) 10^(4)

The young 's modulus of brass and steel are 1.0 xx 10^(11) Nm^(-2) and 2.0 xx 10^(11) N//m^(2) . Respectively . A brass wire and steel wire of the same length extend by 1 mm, each under the same forece . It radii of brass and steel wires are R_(B) and R_(S) respectively, them

The two parallel sides of a trapezium are 1.5m and 2.5m respectively.If the perpendicular distance between them is 6.5 metres,the area of the trapezium is (a) 10m2 (b) 13m2 (c) 20m2 (d) 26m2

The volume change of a solid copper cube 10 cm on an edge, when subject to a pressure of 7 Mpa is (Bulk modulus of copper =140GPa )

A rod PQ of length 1.05m having negligible mass is supported at its ends by two wires one of stell (wire A ), and the other of aluminium (wire B ) of equal lengths as shown in fig. The cross-sectional areas of wires A and B are 1.0mm^(2) and 2.0mm^(2) respectively. At what point along the rod a load W be suspended in order to produce (a) equal stress, (b) equal strains in both steel an aluminium. (Y_("steel") = 200 GPa, Y_("aluminium") = 70 GPa)
