Aclarinetist, setting out for a performance, grabs his 3.05-kg clarinet case (including the clarinet) from the top of the piano and carries it through the air with an upward force of 34.4 n. find the case\'s vertical acceleration. indicate an upward acceleration as positive and a downward one as negative.

Which quantities are scalars? choose all that apply a.distance b.speed c. acceleration d.velocity

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^−2m on an edge at the ocean's surface, decrease by 7.5 x 10−10m^3? explain the formula beyond this point: p=1.0x10^4, b=2.6x10^10, l=9.8x10^−2, delta v=7.5x10^−10. at some point l needs to be cubed. why p is divided by delta v?

What are similarities and differences between refraction, reflection, diffraction and absorption?
