Greenhouse Experiment Summarize your findings from the greenhouse experiment. In your report, answer the following questions as well as explaining your hypothesis, observations, and conclusions. In which box did the temperature rise faster? In which box did the temperature rise higher? In which box did the temperature drop after removing it from the sunlight? How does this experiment demonstrate the greenhouse effect? If you can, compare your results with another student and explain the differences or similarities in your findings. What did you find out from this investigation? Be thoughtful in your answer.

Ahorizontal wire is tied to supports at each end and vibrates in its second-overtone standing wave. the tension in the wire is 5.00 n, and the node-to-node distance in the standing wave is 6.28 cm. (a) what is the length of the wire? (b) a point at an anti- node of the standing wave on the wire travels from its maximum upward displacement to its maximum downward displacement in 8.40 ms. what is the wire's mass?

Three different objects, all with different masses, are initially at rest at the bottom of a set of steps. each step is of uniform height . the mass of each object is a multiple of the base mass : object 1 has mass 4..00m , object 2 has mass 1..96m , and object 3 has mass . when the objects are at the bottom of the steps, define the total gravitational potential energy of the three-object system to be zero. if the objects are then relocated as shown, what is the new total potential energy of the system? each answer requires the numerical coefficient to an algebraic expression. each algebraic expression is given using some combination of the variables , , and , where is the acceleration due to gravity. enter only the numerical coefficient. (example: if the answer is 1..23mgd , just enter 1.23)

Acar starts from rest and accelerates along a straight line path in one minute. it finally attains a velocity of 40 meters/second. what is the car's average acceleration?
