Sebuah bandul diletakkan diatas sebuah balok yang berada didalam air (ρ a = 1000 kg/m 3 ). Massa bandul maksimum yang dapat ditampung oleh balok tersebut jika balok bermassa 50 kg dan memiliki volume 10.10^-2 m3 .

The free body diagram shows a box being pulled to the left up a 25-degree incline. the magnitude of the normal force is

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?

Two resistors r1 and r2 may be connected either in series or parallel across an ideal battery with emf ε. we desire the rate of energy dissipation of the parallel combination to be 8.75 times that of the series combination. if r1 = 105 ω, what are the (a) smaller and (b) larger of the two values of r2 that result in that dissipation rate?
