With the springs removed, release the cart from rest on a level track with a hanging mass of 50 g. determine the cart velocity when passing through the photogate 30 cm down the track from the starting point of the car. use conservation of energy to find the theoretical value of the glider’s velocity. (remember that each mass has kinetic energy when the cart passes through the photogate.) experiment

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.
