Explanation: 1/32 = 1/2^5, so the fossil has aged for 5 half lifes. Assuming the half life is 5,730 years, that's 5 xx 7,730 = 28,650 years old. Answer link. 5 half lifes (half lives?) 1/32 = 1/2^5, so the fossil has aged for 5 half lifes. Assuming the half life is 5,730 years, that's 5 xx 7,730 = 28,650 years old.
HL2 is different, it's obviously more modern, so it will probably feel better, and it has much more story dialogue. But I think you should wait until Black Mesa comes out in full, it's HL1 remake on improved HL2 engine, and it's amazing, I think you will enjoy it. R4Z0R__. • 6 yr. ago. The problem with HL2 now is that it was such a revolutionary game when it came out it completely changed the landscape. Story driven first person games have surpassed it many, many times by now, however that wouldn’t have been possible without HL2 and it’s impact. So yeah, by 2022 standards it’s simply a good game. First, neptunium-238 (half-life 2.1 days) was synthesized, which subsequently beta-decayed to form the new element with atomic number 94 and atomic weight 238 (half-life 88 years). Since uranium had been named after the planet Uranus and neptunium after the planet Neptune , element 94 was named after Pluto , which at the time was considered to
