(i) 1 u = 1.66×10^(-27)kg
16.00u = 16×1.66×10^(-27)
=26.56×10^(-27)
=2.656×10^(-26) kg
(ii) v=d/t
3×10^8 = d/8min
3×10^8×(8×60)sec =d. (1min=60sec)
d = 3×480×10^8
d = 1440×10^8 metres
d = 1.44×10^8 km. (1m=1/1000km)
(iii)d = 8.33 light min
d = 8.33×1.798754748×10^10
d= 14.98359×10^10
d=1.498359×10^11
d(approximately)=15×10^11m
