Welcome back Pretty~Nelly — missed you this week. Here are the solutions for questions 7 through 11 based on the provided data: Step 1: Address Question 7 (Plotting the graph) I cannot plot a graph directly. However, the data provided in the table will be used to calculate the slope as requested in the next step. The graph would show V (apparent loss in weight in oil) on the vertical axis against U (apparent loss in weight in water) on the horizontal axis. Step 2: Determine the slope, S, of the graph (Question 8) The slope S is calculated as the change in V divided by the change in U. We can use any two points from the table, for example, the first point (U_1, V_1) = (0.04, 0.06) and the last point (U_6, V_6) = (0.12, 0.14). S = ( V)/( U) = (V_6 - V_1)/(U_6 - U_1) S = 0.14 N - 0.06 N0.12 N - 0.04 N S = 0.08 N0.08 N S = 1.0 Step 3: Physical significance of the slope, S (Question 9) According to Archimedes' principle, the apparent loss in weight of an object when immersed in a fluid is equal to the weight of the fluid displaced. The apparent loss in weight in water, U = W_1 - W_2 = _water g V_object. The apparent loss in weight in vegetable oil, V = W_1 - W_3 = _oil g V_object. Therefore, the slope S = (V)/(U) = _oil g V_object_water g V_object = _oil_water. The physical significance of the slope S is the relative density (or specific gravity) of the vegetable oil. Step 4: Approximate density of vegetable oil (Question 10) Given that the density of clean water is 1 g/cm^3 and the slope S = _oil_water. We can calculate the density of vegetable oil: _oil = S × _water _oil = 1.0 × 1 g/cm^3 _oil = 1.0 g/cm^3 Step 5: State any precautions taken (Question 11) • Ensure the object is fully immersed in the liquid without touching the bottom or sides of the beaker. • Read the spring balance at eye level to avoid parallax error. • Ensure the spring balance is calibrated to zero before taking measurements. • Avoid air bubbles clinging to the object when it is immersed in the liquid, as this would affect the buoyant force. • Repeat measurements for accuracy and consistency.
