Adisk between vertebrae in the spine is subjected to a shearing force of 600 n. find its shear deformation, taking it to have a shear modulus of 1x10^9 n/m^2. the disk is equivalent to a solid cylinder 0.700 cm high and 4.00 cm in diameter. a)3 î¼m
b)3 mm
c)3 cm
d)3 km

1point) a skydiver weighing 130 lb (including equipment) falls vertically downward from an altitude of 14,000 ft and opens the parachute after 20 s of free fall. assume that the force of air resistance, which is directed opposite to the velocity, is of magnitude 0.85|v|0.85|v| when the parachute is closed and is of magnitude 17|v|17|v| when the parachute is open, where the velocity vv is measured in ft/s. assume that acceleration due to gravity has magnitude 32 ft/s/s; remember that weight is the product of mass and gravitational acceleration. find the speed of the skydiver when the parachute opens. speed is 150.6121788 ft/s find the skydiver's height when the parachute opens. height is 2338.98591 ft find the limiting velocity vlvl after the parachute opens. (think about whether this should be positive or negative.) vl=vl= 7.647 ft/s

Ihave a density of 1.61g/cm^3 and a mass of 28g. find the missing value

Amajor difference radio waves, visible light, and gamma rays is the of the photons, which results in different photon frequencies and wavelengths
