Ahorizontal spring mass system is to be constructed. a spring which has a spring constant of 3 kg/s2will be used. the system should be designed so that when it is released and vibrating freely (there is no forcing) the amplitude of its vibrations will decay like e−0.6t, and it should oscillate with a period of 2 seconds. (although the motion is oscillatory it is not strictly periodic because the amplitude decays exponentially. in this context "period" refers to the period of the sine and/or cosine functions that create the oscillations in the motion.) based on these constraints determine the mass of the object, m (kg), to be used, and also determine the value of the friction coefficient, b (kg/s).

In a laboratory, nakisha mixes sodium hydroxide solution with an indicator called phenolphthalein. when combined, they create a pink solution. nakisha wonders if mixing other solutions with phenolphthalein will also create this pink color. how could she use the scientific inquiry process to explore it further?

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?
