The numbers on a sack of fertilizer, like 13-13-0, are referring to the proportion of _____ in the bag.                                                                                                                                                                                                 

Match the picture of each if the weeds to the name.

The goal for plants is to have higher rates of Photosynthesis than ryes of Cellular Respiration.

Match the pest to it’s description. Use each of the following answer choices once.

There are prepared maps dividing the U.S. and Canada into 11 zones based on average winter temperatures. This map is called the ______.                                                                                                             

Continue the previous problem: Determine the speed of the object near position 2, where x = {x} cm.  Enter the speed in the unit of cm/s. The original problem: A 250-g object connected to a light spring with a spring constant of 1.00 N/m sits on a frictionless horizontal table. Suddenly, the object is knocked by a force causing it to move towards right and then vibrate back and forth with an amplitude of 10.0 cm as shown in the drawings.   

In a spring-mass system, a 100-g mass block oscillates on a frictionless tabletop.  It’s position x varies with time t as: x(t)=(5.00 cm) x sin(2t) What is the amplitude of vibration in cm?  Enter your unit as “cm”.

Continue the previous problem: What is the position of the mass  in cm at t = π/{n} (sec)?   Enter your unit as “cm”. The original problem: In a spring-mass system, a 100-g mass block oscillates on a frictionless tabletop.  It’s position x varies with time t as: x(t)=(5.00 cm) x sin(2t)

A 0.717-g guitar string is 0.629 m long.  The string is under a tension of 73.9-N.  What is the frequency of the {n}th  harmonics in Hz?  Enter your unit as “Hz”.

Consider the following mass distribution where the x- and y-coordinates are given in meters: 5.0 kg at (3.0, 0.0) m, 3.0 kg at (0.0, {y1}) m, 4.0 kg at (0.0, 0.0) m and a fourth object of 8.0 kg at (2.0, {y2}) m.  Find y coordinate of center of gravity for this configuration. Enter your unit as “m”.
