Part (d) Write an equation for the pressure difference AP between the inside and outside of the ball when it is submerged a distance y below the surface of the water. Expression : AP = Select from the variables below to write your expression. Note that all variables may not be required. a, B, Q, 0, a, d, g,j, k, m, P, PG, t, x, y Part (e) Solve the pressure equation for the depth (in meters) at which the pressure difference between the inside and outside of the ball will become zero. At this depth the pressure inside the basketball is the same as the pressure outside the ball. Numeric : A numeric value is expected and not an expression. y = Part (f) At what depth, in meters, would the pressure difference between the inside and outside of the ball be zero if the ball were submerged in mercury (g = 13,500 kg/m3) instead of in water? Numeric : A numeric value is expected and not an expression. y =

Where did you get the 3 from for the distance of q?

What is the degree of freedom of the two questions

Please answer 3, 4, 5, 6, 8, 9, 10, 12 1 is 0, 2 is 0, 7 is point A, 11 is 2.  I included a picture of someone who solved but they were mostly incorrect. Please do not answer if the solution set I provided with the incorrect answers was you. I appreciate the attempt, but the solutions for 3, 4, 5, 6, 8, 9, 10, 12 were marked wrong, so unless you have different answers, please do not submit the same incorrect solution set. The wheel is attached to the spring. The mass of the wheel is m=20 kg. The radius of the wheel is 0.6m. The radius of gyration kG=0.4 m. The spring’s unstretched length is L0=1.0 m. The stiffness coefficient of the spring is k=2.0 N/m. The wheel is released from rest at the state 1 when the angle between the spring and the vertical direction is θ=30°. The wheel rolls without slipping and passes the position at the state 2 when the angle is θ=0°. The spring’s length at the state 2 is L2=4 m. (1) If the mass center G is set as the origin (datum), the gravitational…

Please answer from  iv onwards as you have already sent me the answer to the other please show working and correct answer
