Aball is on the end of a rope that is 1.72 m in length. the ball and rope are attached to a pole and the entire apparatus, including the pole, rotates about the pole's symmetry axis. the rope makes an angle of 64.0° with respect to the vertical. what is the tangential speed of the ball

Neurons are components of the nervous system of the body that transmit signals as electrical impulses travel along their length. these impulses propagate when charge suddenly rushes into and then out of a part of the neutron called an axon. measurements have shown that, during the inflow part of this cycle approximately 5.6x10^11 na per meter, each with a charge of e enter the axon. how many coulombs of charge enter a 1.10 cm length of axon during this process
