Electrical power P is given by the expression `P = (Q xx V) div` time.
What do the symbols Q and V represent ?

Electrical power P is given by the expression P = (Q xx V) div time. Express the power P in terms of current and resistance explaining the meaning of symbols used there in.

In electrocardiography P-Q interval represents :

The Boolean expression P+bar(P)Q , where P and Q are the inputs of the logic circuit, represents

The distance between two moving particles P and Q at any time is a.If v_(r) be their relative velocity and if u and v be the components of v_(r) , along and perpendicular to PQ .The closest distance between P and Q and time that elapses before they arrive at their nearest distance is

In Figure if the potential at Point P is 100 V , what is the potential at point Q?

Two identical discs of same radius R are rotating about their axes in opposite directions with the same constant angular speed omega . The discs are in the same horizontal plane. At time t = 0 , the points P and Q are facing each other as shown in the figure. The relative speed between the two points P and Q is v_(r) . In one time period (T) of rotation of the discs , v_(r) as a function of time is best represented by

The diagram, given below, represents two inequations P and Q on real number lines : Write down P and Q in set builder notation.

The displacement-time graphs of two particles P and Q are as shown in the figure. The ratio of their velocities V_P and V_Q will be

Three motorcyclists P, Q and R, initially at the same point, start moving from rest on the same road in the same direction. They move with constant acceleration a_p,a_Q and a_R(a_Pgt a_Qgt a_R) . At any instant ,the separation between P and Q is (3)/(2) times the separation between Q and R . Then at any instant (2v_P+3v_R)/(v_Q) = where v_P,v_Qand v_R are instantaneous velocities of P, Q and R respectively.

The diagram, given below, represents two inequations P and Q on real number lines : Represent each of the following sets on different number lines : (a) P cup Q (b) P cap Q (c ) P - Q (d) Q - P (e ) P cap Q (f) P cap Q
