25. A particle is performing simple harmonic motion along
x-axis with amplitude 4 cm and time period 1.2 s. The min-
imum time taken by the particle to move from x = 2 cm to
x= +4 cm and back again is given by​

Apossible explanation for a set of facts that can be tested by further investigation is called

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?
