Suppose you must design an experiment to test how a paper airplane's shape affects the distance it will fly. Your plane must fly halfway across your classroom to get the best grade. The teacher reminds you to use both imagination and logical reasoning in your design.

Write a procedure for an experiment that tests how a paper airplane's shape affects the distance it will fly. Then, describe how you might use both imagination and logical reasoning to increase your chances of discovering an airplane shape that will fly at least halfway across the classroom.

Answer:

The larger the paper airplane the more it will weigh, the more it weighs the more lift will be needed to keep it flying. Eventually, the weight will become greater than the lift and the paper airplane will decend to the ground. In adition the larger the paper airplane the larger its wings can be

a studentistrying to design an artifical eardrum fo their science fair project. they made their eardrum hollow to cut down oncost and weight. when they tested howlong it took to test the subject tohear deep, they found that their control ear drum made outof wood did better than their created one. the temperature that day wa 98 fahrenheit.
determine which statement supports the students findings.
a.the created eardrum performed worst because sound travels faster in solids due to large distance between the particals
b. the created eardrum performed worst because sound travels faster in solids due to the small distance between the particles.
c.the created eardrum performed worst because sound travels slower in air due to the small distance between the particles.
d.the created eardrum performed worst because sound travels slower through air in high temperatures due to the particles moving slower.

they know that tsunamis,or ocean waves with a very large wave amplitude, happens after anther event, such as an earthquake or landslide has dramatically shifted the earths crust and therefore the water above that crust.while difficult to see the amplitude and wavelength of the individual waves while they are far out at sea, we can see how large they are as they get into shallower areas as they approach the shoreline. based on the model and explanation, how does an earthquake cause tsunamis?
A. an earthquake seismic wave provides mechanical energy to the ocean. as energy is added the amplitude of the wave is increased.
B. as the earthquake vibrates more waves are created. more waves means that there is less space between them decreasing the wavelength. because amplitude is inversely related to wavelength, this that the waves must be less energetic.
C. as the earthquake creates more waves the frequency is increased. because amplitude is directly related to frequency, the amplitude is also increased.
D. an earthquake seismic waves overlap and build upon each other as the earth continues to shake. as the earth shakes more, the amplitude of the wave increases.
