Question

∆m=0,019a.e.m c=3•10⁸mc

Answer 1

∆m=0,019a.e.m c=3•10⁸mc

Answer 2

It seems like you're providing a mathematical expression with some symbols, but it's not clear what you're asking.

∆m = 0.019 a.e.m c = 3 × 10^8 m/s

It looks like you're referring to the change in mass (∆m) in terms of atomic mass units (a.e.m) and the speed of light (c) in vacuum. If you have a specific question or if you need help with a particular calculation related to this expression, please provide more context so I can assist you effectively.
