Cumulative Problem 1 A typical human cell is approximately 11 um in diameter and enclosed by a membrane that is 4,4 nm thick. To
simplify the calculations, model the cell as a sphere.
1) What is the volume of the cell? (Express your answer to two significant figures.)

At very high pressures, gases become and will eventually a) more dense; become hotter b) more dense; change to a liquid or solid c) less dense; combust d) less dense; turn into a liquid

The process of predicting values that extend beyond the range of data points is called absolute value extrapolation interpolation prediction for any given: )

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?
