Speed = Distance/Time Speed = 3 Time = 60 Distance = Speed x Time Distance = 3 x 60 = 120m
The first step is to identify which components of the ‘SUVAT equations of motion’ the question gives us. Here we have the initial (u) and final (v) speeds, the distance (s) and ...
In beta-minus decay, a neutron decays into a proton plus an electron. For alpha decay, the mass number decreases by 4 and the atomic number decreases by 2. For beta-minus decay, the mass number remains th...
When the nucleus of an atom is unstable, it occasionally emits either waves or particles to stabilise itself.
The three types of radiation are: Alpha particles, Beta particles and Gamma waves.
For this, we need to use the equation F = 1/T (where F = frequncy, and T = period). The period of this wave is the time taken for one whole wave to pass i.e. from one wave crest to the next wave crest. ...
