Question 11 (10 points) Listen Two ice skaters, Daniel (mass = 65.0 kg) and Rebecca (mass = 45.0 kg) are practicing on the ice. Daniel stops to tie his lace, and while at rest he is struck by Rebecca, who is moving 12.0 m/s before she collides with him. After the collision, Rebecca is moving forward at 8.50 m/s at a 53-degree angle with respect to her initial direction. What is the velocity vector (magnitude and direction, or x- and y-components) of Daniel after the collision? Assume frictionless ice. Hint: Momentum is conserved separately in both the x- and y- directions. (1.8i -4.7j) m/s (4.8i -4.1j) m/s (4.8i -4.7j) m/s (4.0i -4.6j) m/s

Is the following a good example of a valid conclusion?Studies have shown a correlation in children who watch violence on t.v. and violent acts toward others. Studies have also shown a correlation in children between playing violent video games and the number of violent acts toward others.Therefore, it is logical to conclude that watching violence on t.v., video games, etc. leads children to violent acts toward others.Group of answer choices

How do eukaryotic cells ensure that newly translated proteins are correctly localized within the cell? The Shine-Dalgarno sequence base-pairs with the 16S rRNA Signal sequences in the mRNA cause it to be sent to the correct location to be translated Specific amino acid sequences in the new protein are recognized and used to move it to the correct location Proteins begin to fold as they emerge from the ribosome

D. Mean is 1 and standard deviation is 0. 15. What is the difference between the central limit theorem (CLT) and law of large numbers (LLN)? A. CLT concerns convergence of sample mean while LLN concerns convergence of the distribution of sample mean. B. LLN concerns convergence of sample mean while CLT concerns convergence of the distribution of sample mean. 16.
