Chemotherapy is a cancer treatment that uses drugs to kill cancer cells. However, it is problematic, because the drugs also kill every healthy cell that they contact. How could nanotechnology best be used to improve the treatment of cancer with chemotherapy?

A: A nanometer-size carrier could be designed to bring the chemotherapy drugs only to cancer cells.
B: A nano carbon wire could be designed that would aid in the manufacture of chemotherapy drugs.
C: A quantum dot could be used to watch where the chemotherapy drugs go in the body.
D: Biomaterials could be made that would allow for cell growth within the cancer cells so that they are easier to find.

3. a worker pushes a 30.5 kg polished stone along a polished table with a force on bonin a straight line for 5.20 s after starting from rest. there is no friction between thestone and the table. at the end of the table. the stone is hooked to a cable with a lengthof 62.0 cm to rotate it to a rough table to store until they can be picked up. the roughtable has a coefficient of static friction 0.702 with the polished stone. remember that 8= 9.80 m/s2a) what is the speed of the stone when it is hooked to the cable? b) what is the tension in the cable while the stone is rotating? (there is still nofriction)c) how much force is needed to make the stone begin sliding from rest on therough table? ius = 0.70262.0 cm30.5 kg20.5 kg6= 0
