Laboratory specimens for the detection of infectious disease should be collected:

Enforcement of the Federal Food, Drug and Cosmetic act is the responsibility of the FDA.

[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?

Which type of media is designed to distinguish microorganisms on the basis of certain growth characteristics?

[2 points] A marble column with a radius of 0.5 meters and height 9.0 meters shortens by 2.4×10-5 meters when a load is placed on it. The elastic modulus of marble is 5.0×1010 N/m2. What is the mass of the load in kg?

“Back in the day” compact disk (CD) players would spin CDs at specific angular velocities to read data at different radii on the disk. If the diameter of a CD is 12 cm, and the player is reading data off the edge of the disk at a linear speed of 1.26 m/s, how fast is the CD spinning in revolutions per minute (rpm)?
