PLEASE HELP ASAP
1) During a transformation, a positive radon nucleus repels a positive helium nucleus
(m = 6.64 × 10–27 kg), giving it an energy of 7.37 × 10–13 J. How fast is the helium
nucleus moving when it is far away from the radon nucleus? Draw an energy bar chart
to assist you.

2) A positive charge of +7.2 μC and a positive charge of +6.64 μC are 10 cm apart, at
rest. After t seconds, the particles are at a distance 15 meters apart with velocities
–8.7 m/s and 9.1 m/s, respectively. Draw an energy bar chart of the situation and
determine the direction of the forces and velocities of each charge.

Respuesta :

I dotn know the first question but the second one. If u think about it positive charge is +7.2 so then add +6.64 then get the answer to that then u, know there are 60 seconds in a miniute and
