Question

I believe all of these statements are false, but could you explain why for each please? THANK YOU!!
Question 9: Now, consider a beaker of water placed on a scale. The combined body is then suspended in the water. Comment on each of the following student predictions regarding what happens to the reading of the scale. With which do you agree or disagree? Explain. 1. We predict the reading of the scale will not change because the object is suspended in the water and never touches the bottom of the beaker. 2. We predict the reading of the scale will increase by an amount equal to the object's weight because water is incompressible so we are effectively weighing the object and the beaker together. 3. We predict the reading of the scale will decrease by an amount equal to the tension force suspending the object.

Answer 1

'FBood Beaker la le leverthing 12 New reading N = FRT (MB +MW) g original reading 1) The reader statement student prediction is wrong since There will be an increase in reading of the beaker equal to The bonyant for ce applied on the combined mass . Fe mg - T 2) The student prediction is wrong since some of the weight of the co object is supported by Tension in the string and hence it will not appear on scale. 3) The student prediction is fabe since the reading of slade will increase by FB a C mg -T) FB : bougant force on the combined mass mg = weight of combined mass TE Tersion in the strong
