The figure shows a graph of electric potential versus position along the x-axis. a proton is originally at point a, moving along in the positive x direction. how much kinetic energy does it need to have at point a in order to be able to reach point e (with no forces acting on the proton other than those due to the indicated potential)? points b, c and d have to be passed on the way.

An airplane flying parallel to the ground undergoes two consecutive displacements. the first is 76 km at 39.8◦ west of north, and the second is 156 km at 59.9◦ east of north. what is the magnitude of the plane’s total displacement? answer in units of km. 020 (part 2 of 2) 10.0

Asun-sized star will spend most of its lifetime as a: white dwarf red giant protostar main-sequence star

Will give brainliest! which statement best describes the difference between strong nuclear forces and weak nuclear forces? weak nuclear forces are involved when certain types of atoms break down. strong nuclear forces are responsible for holding atoms' nucleus together. weak nuclear forces hold bonds between atoms together. strong nuclear forces hold together the nucleus of an atom. strong nuclear bonds prevent atoms from falling apart. weak nuclear bonds prevent compounds from falling apart. strong nuclear forces are involved in breaking electrons from their shells. weak nuclear forces hold protons in the nucleus.
