Because blood contains charged ions, moving blood develops a hall voltage across the diameter of an artery. a large artery with a diameter of 0.75 cm has a flow speed of 0.9 m/s. if a section of this artery is in a magnetic field of 0.24 t, what is the maximum possible potential difference across the diameter of the artery? answer in units of mv.

If the ama of the inclined plane below is 2, calculate the ima and efficiency. ima = efficiency =

Astudent pushes a 60-n block across the floor for a distance of 10 m. how much work was done to move the block

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
