The microbiology laboratory receives a genital culture from a 28-year-old female. The specimen direct Gram stain reveals, gram-positive cocci in clusters and gram-negative cocci in chains. The microbiologist inoculates a sheep blood agar plate, a chocolate agar plate, a modified thayer martin plate and a LIM Broth (selective enrichment for group B streptococci). The second shift microbiologist identifies the discrepancy and must take corrective action. The discrepancy indicates:

[3 points] A pendulum has a period of 1.87 seconds on Earth. What would be its period in seconds on Venus, where the acceleration due to gravity is about 0.91 that of Earth’s?

[2 points] Using the vectors in the figure, what is the magnitude of vector E if E = B – A? (Note: this is a vector equation.)

If the gravitational potential energy of a pole vaulter changes by 2080 J for a 4.0-meter jump, what is the mass of the pole vaulter in kg?

A 5 kg mass is hung from a 2-meter-long cable, causing the cable to stretch by 3 mm. Suppose a 15 kg mass is hung from the same cable. By how much does the cable stretch in millimeters?
