Aspool of thin wire (with inner radius r = 0.45 m, outer radius r = 0.60 m, and moment of inertia icm = 0.8208 kg·m2) pivots on a shaft. the wire is pulled down by a mass m = 1.300 kg. after falling a distance d = 0.500 m, starting from rest, the mass has a speed of v = 63.1 cm/s. calculate the energy lost to friction during that time.

Write the equation for momentum, first using symbols for the variables, then using words for the variables.

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?

Awoman holds a book by placing it between her hands such that she presses at right angles to the front and back covers. the book has a mass of m = 1.8 kg and the coefficient of static friction between her hand and the book is μs = 0.67. no attempt 50% part (a) what is the weight of the book, fgb in newtons?
