5. A group of students is making paper airplanes. They think that the kind of paper and the design of the airplane may affect how far each paper airplane flies. The students first test if the kind of paper affects how far the airplane flies. They make several airplanes out of different kinds of paper, using the same design. Why is it important that all the airplanes have the same design? A. By using the same design, the students can leam about the effect of the design. B. If they do not use the same design, the students cannot learn about the effect of the paper. C. By using the same design, the students can learn about both the effect of the design and the effect of the paper. D. It is NOT important for the airplanes to have the same design because the students are not testing the effect of the design.

The pressure increases by 1.0 x 104 n/m^2 for every meter of depth beneath the surface of the ocean. at what depth does the volume of a pyrex (bulk modulus 2.6 x 1010n/m^2) glass cube, 9.8 x 10^β2m on an edge at the ocean's surface, decrease by 7.5 x 10β10m^3? explain the formula beyond this point: p=1.0x10^4, b=2.6x10^10, l=9.8x10^β2, delta v=7.5x10^β10. at some point l needs to be cubed. why p is divided by delta v?
