Answer 1

) these isotopes have almost identical chemical properties. ... (ii) they are electricity neutra

Answer 2

Explanation:

minute hand completes one rotation for 1 hour i.e, 60 mins

60 sec= 1min

100 sec= 1.6666667min. (1+40/60)

60 min= 360°

1.66666667 mins=360/60×1.66666667=10°

a=10°

r=10cm = 0.1m

distance covered = 2πr×a/360

= 2π×0.1×10/360

= 2π×1/10×10/360

= 2π/360

= π/180
