A nucleus `"_n^mX ` emits one `alpha`-particles and two `beta`-particles. The resulting nucleus is:

A uranium nucleus ""_(92)U^(238) emits an alpha particle and a beta - particle in succession. The atomic number and mass number of the final nucleus will be

When a radio active isotopes "_88Ra^228 decays in series by the emission of three alpha -particles and a beta -particle, the isotopes finally formed is ...

""_(92)U^(238) emits 8 alpha particles and 6 beta particles. What is the neutron / proton ratio in the product nucleus.?

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

A couple is acting on a two particle system. The resultant motion will be:

When a boron nucleus ( ._5^10B ) is bombarded by a neutron, an alpha-particle is emitted. Which nucleus will be formed as a result?

The number of beta particles emitted by a radioactive substance is twice the number of alpha particles emitted by it. There resulting daughter is an:

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
