Answer 1

m2 to np25 | Ae ( >> DE: - 2.170x70" ( ) ) RH=2.179x1018 SAE = -2-179 x 10 => 9€ - 2.149x1078 (200) AE = 45.759 x 10 20 T AE = 4.5759 x 1015 J Correct option is option (c) 4.9x15 19 J Close to AE all mass m= 13 kg N= 12 m/sec use h = 6.626x1034 J. See (plank's Constant) debroglie wowe lengan x = h mv 6.6268 10 34 I-8ec 13 kg 12 m/sec x = 0.04247 x 10 34 m 1 - 4.247 X10 36 Corred antwer amox A 4.251-36 Option (A) 4.2 x 16 36 m
