Establish relation between I,H,V and theta. , CLASS 10 | Question Paper 2013 | PHYSICS Doubtnut

The relation between B_H, B_v, and B is

A man wlaking briskly in rain with speed v must slant his umbrella forward making an angle theta with the vertical . A student derives the following relation between theta and v : tan theta=v and checks that the relations has a correct limit : as v rarr 0, theta rarr 0 , as expected . (We are assuming there is no string wing and that the rains falls vertically for a stationary man). Do you think this relation can be correct ? If not, guess at the correct relation .

For real gases, the relation between P, V and T is given by an van der Waals equation, (P+(an^(2))/(V^(2)))(V-nb)=nRT . For the following gases CH_(4),CO_(2), O_(2),H_(2) which gas will have (i) highest value of 'a' and (ii) lowest value of 'b' respectively?

In previous question, what is the relation between h_1 and h_2

Following is the relation between current and charge I=AT^(2)e^(qt//V_(L)) then value of V_(L) will be

The velocity-displacement graph of a particle is shown in Fig. 2 (EP). 10 . (a) Write the relationbetween (v) and (x). (b) Obtain the relation between acceleration and displacement and plot it . . . .

Using method of dimensions, establish relation among given physical quantities : (a) Heat H produced in a wire depends on current i flowing through it, its resistance R and time t . (b) The magentic field F_(m) acting on a moving charged particle in magnetic field depends on charge on particle q , its speed v and magnetic field B Dimensional formulae : R : ML^(2) T^(-3) A^(-2), B : MT^(-2) A^(-1)

Two masses A and B are connected with two an inextesible string to write constraint relation between v_(A) & v_(B) Student A : v_(A) cos theta=v_(B) Student B : v_(B) cos theta=v_(A)
