If `x = 20 and y = 40`, then `x and y` are: A. Directly proportional B. Inversely proportional C. Neither directly nor inversely proportional D. Cannot be determined​

Both x and y are in direct proportion, then 1/x and 1/y are

In case of inverse proportion a_2 __ b_2

Consider the following statements : 1. If x is directly proportional to z and y is directly proportional to z, then (x^(2) - y^(2)) is directly proportional to z^2 . 2. If x is inversely proportional to z and y is inversely proportional to z, then (xy) is inversely proportional to z^2 . Which of the above statements is/are correct?

If x and y are in inverse proportion, then (x + 1) and (y + 1) are also in inverse proportion

If the kinetic energy of body is directly proportional to time t , the magnitude of force acting on the body is (i) directly proportional to sqrtt (ii) inversely proportional to sqrtt (iii) directly proportional to the speed of the body. (iv) inversely proportional to the speed of the body.

Law stating that "force is directly proportional to product of charges and inversely proportional to square of separation between them" is called

The value of electric potential at a distance r from a point charge will be (A) proportional to r (B) inversely proportional to r (C) proportional to r^(2) (D) inversely proportional to r^(2)

When x and y are in indirect proportion and if y doubles then x becomes_______

If x and y are inversely proportional then _____ = k where k is positive constant.
