If an agent can only inhibit gram-postive bacteria, then it has a narrow spectrum.

If an agent can only inhibit gram-negative bacteria, then it has a broad spectrum.

When performing a Kirby Bauer disc diffusion assay, the smaller the zone the ________ susceptible the bacteria are to the agent.

A 65.0 kg mountain climber hangs below a rock outcropping from a nylon rope. The diameter of the nylon rope is 0.00800 m. What is the change in length of the rope if it was 45.0 m long before she hung from it?        Nylon:  Shear modulus: 2.00 x 109 N/m2    Young’s modulus: 5.00 x 109 N/m2     Bulk modulus: 6.00 x 109 N/m2

A water balloon is thrown straight down with an initial speed of 12.0 m/s from a second floor window, 5.00 m above ground level. If air resistance is negligible, how fast is the balloon moving when it is 0.500 m above the ground?  USE ENERGY CONCEPTS TO SOLVE.

Trying to escape Vanessa and Jenny, Joshua runs away down the sidewalk with a velocity of 3.60 m/s and leaps into a wagon that is initially rolling directly towards him at 0.500 m/s.  If Joshua’s mass is 65.0 kg and the mass of the wagon is 80.0 kg, what is the wagon’s final velocity?  Assume that friction is negligible.

Suppose a 76.0-kg safe is sitting on a wood floor. A robber, whose arm muscles are too puny to lift the safe, attempts to push it across the floor.  If he pushes with a horizontal force of 300.N, will he succeed in moving the crate?  The coefficient of kinetic friction is 0.300, and the coefficient of static friction is 0.500.  Show mathematically, and explain in words, how you reach your answer.
