1. (Unicamp) Suponha que um meteorito de 12 1,010x10 kg colida frontalmente com a Ter- ra 24 (6,010x10 kg) a 36.000 km/h . A colisão é perfeitamente inelástica e libera enorme quantidade de calor. a)Qual é a ordem de grandeza da energia cinética do meteorito se transforma em calor?

no because after the troops were pulled many blacks were killed by hangings lynchings and other cruel ways which in a way interrupted the reconstruction of the south and differed from the way abraham lincoln had an idea of reconstruction

step-by-step explanation:

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
