Question
The year is 3691. A suburbanite family visits a historical museum where they admire an exhibit on 20th century cooking. In one of the cases lies a can of SPAM produced in 1996. Assuming complete homogeneity of the meat product's nuclei (and yes, we are assuming it's radioactive!), how many nuclei are still present if the half-life of the nuclei is 236 years and the can contained 5.0 times 10^8 nuclei of SPAM when it was produced? nuclei A spaceship is moving at 0.72 c (0.72 times the speed of light) with respect to the earth. An observer on the spaceship measures the time interval between two events as 34 hrs. If the spaceship had been moving with a speed of 0.9 c with respect to the earth, what would the time interval between the events have been? Dt_0.9 c = hrsExplanation / Answer
b)
At .72c time is stretched by a factor of 1.43
At .9c time is stretched by a factor of 2.3
the original length of time was and then multiply it by 2.3
In other words 34 = 1.43 of X
X = 24 hrs
So
2.3 (24) = 55.2 hrs
