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”.

A girl of 50.0-kg skating at 10 m/s crashes into another girl of mass 35.0-kg moving in the same direction at 8.0 m/s.  Assuming the impact lasts 0.15 s, after which they move together, how much energy is lost in this collision (the absolute value in J)?   Enter your unit as “J”.

A 50.0-g uniform meter stick is supported by a fulcrum at the 30.0-cm mark. A 100-g mass is hung at the 50.0-cm mark.  What mass (in g) should you place at the 10.0-cm mark to perfectly balance the stick in horizontal position?  Enter your unit as “g”.
