Loghan and kyle want to see if the type of ice cream in the freezer affects how hard or soft it is. each time they placed a new brand of ice cream in the freezer, they put it in a different place. they made sure that the freezer temperature was the same each time. they also made sure that the freezer door remained closed after each carton was placed inside it. based on their experiment design, their results should be reliable.

Two conductors, a and b, are each in the shape of a tetrahedron. but of different sizes. they are charged in the following manner: 1. tetrahedron a is charged from an electrostatic generator to charge q. 2. tetrahedron a is briefly touched to tetrahedron b. 3. steps 1 and 2 are repeated until the charge on tetrahedron b reaches a maximum value. if the charge on tetrahedron b was q/4 after the first time it touched tetrahedron a. what is the final charge qbmax on tetrahedron b?
