Select the statements that are TRUE. Electrophilic aromatic substitution reactions have energies of activation that are very low
. Dienes and alkenes are much more stable than benzene rings. Benzene and its derivatives tend to undergo electrophilic aromatic substitution reactions. Addition reactions with benzenes lead to the loss of aromaticity. Benzene and its derivatives tend to undergo electrophilic aromatic addition reactions. Benzene and its derivatives undergo a type of substitution reaction in which a hydrogen atom is replaced by a substituent, but the stable aromatic benzene ring is regenerated at the end of the mechanism.

Straight line in the direction of the tangential velocity the ball had at the moment the string broke
Explanation:
After the string breaks, the ball now disconnected from the centripetal force that was exerted via the string, continues its travel in a straight line in the direction of the tangential velocity it had at the moment the string broke.
