Tooth decay is caused by ________.

ANF causes

""_zX^(A) to ""_zY^(A) This reaction is possible in _____________ decay.

A free ^238U nucleus kept in a train emits an alpha particle. When the train is stationary, a nucleus decays and a passenger measures that the separation between the alpha particle and the recoiling nucleus becomes x at time t after the decay. If the decay takes place while the train is moving at a uniform velocity v, the distance betwen the alpha particle and the recoiling nucleus at a time t after the decay as measured by the passenger is

What is the disease caused caused by the presence of 47 chromosomes in humans? Explain it.

The nucleus undergo nuclear decay to get converted into a more _________.

Free ^238 U nuclei kept in a train emit alpha particles. When the train is stationary and a uranium nucleus decays, a passenger measures that the separation between the alpha particle and the recoiling nucleus becomes x in time t after the decay. If a decay takes place when the train is moving at a uniform speed v , the distance between the alpha particle and the recoiling nucleus at a time t after the decay, as measured by the passenger will be
