Question 1: Write the following statements in notations and equations. As shown in the example, use the symbols given in ( ) to represent the variables. Statement Example The square of the period (T) is directly proportional the cube of the radius (r) of the orbit. Notation Tzar3 Equation T2 =kr3 The volume (V) of gas is directly proportional to the absolute temperature (T) of the gas. Centripetal force (F) is inversely proportional to the radius (r) of the orbit. The volume (V) of a sphere is directly proportional to the cube of its radius (r). The gravitation force (F) between two objects is inversely proportional to the square of the distance between them (d) Q-2. Tell whether the following equations express direct or inverse proportions with D or I respectively. The symbol "k" represents constant. O
