up incline.png A block is shot up an the above incline with an initial speed of 12.0 m/s.  It slides up the ramp and then back down.  If the coefficient of kinetic friction between the block and the incline is 0.40 will be the speed of the block when it slides back down to the bottom of the ramp?

A mass m1 = 15.0 kg traveling East at 12.0 m/s undergoes an elastic, head on, collision with a mass m2 traveling West at 14.0 m/s.  After the collision m1 is traveling West at 10.0 m/s.  What was the mass of m2?

In 2018, a genome-wide association study for major depressive disorder (MDD) was published in the journal Nature Communications. The first Manhattan plot below is from that publication. In this study, genome-wide significant SNPs had a P  7.3, and the cutoff for suggestive SNPs was P=10−6 [-Log10(6)].   1) How many independent loci are associated with MDD at a genome-wide significance level in the 2018 GWAS? [2] 2) If the only difference between these two studies is sample size, which GWAS has the biggest sample size? [2019] 3) If the only difference between these two studies is sample size, do the genome-wide significant variants identified in the 2018 study have a bigger or smaller effect size than most of the genome-wide significant variants identified in the 2019 study? [bigger]
