Solve the all given part of following question:
Question: A typical human cell is approximately 10 um in diameter and enclosed by a membrane that is 5.0 nm thick. To simplify the calculations, model the cell as a sphere.
Part I: What is the volume of the cell? (Include the membrane in your calculation.)
Part II: What is the volume of the cell membrane?
Part III: What percent of the cell volume does its membrane occupy?
Please show work and steps. Do not just copy paste from the internet. Thanks.
A sphere of radius 1.0 cm is dropped into a glass cylinder filledwith a viscous liquid. The mass of the sphere is 12.0 g and thedensity of the liquid is 1200 kg/m3. The sphere reaches a terminalspeed of 0.15 m/s. What is the viscosity of the liquid?
assume you are 90 cm from a plane mirror. What area of the mirror is used to reflect the rays entering one eye from a point on the tip of your nose if your pupil diameter is 5.5 mm.
Suppose a news report stated that starship Enterprise had just returned from a 5 year voyage while traveling at 0.81c. If the report meant 5.0 years of Earth time, how much time elapsed on the ship
Imagine removing one electron from every atom in a tiny cube of gold 1 mm on a side. (Never mind how you would hold the resulting positively charged cube together.) Do the same thing with another such cube a meter away.
