Some of the hydrogens are bonded directly to the carbons of the parent alkane according to the numbering based on IUPAC substitutive nomenclature convention. Identify the carbon number of the parent (according to IUPAC substitutive nomenclature numbering of the parent) to which the hydrogens resonating at the indicated ppm are bonded.
C) Signal at 1.79 ppm Input a number.
D) Signal at 1.65 ppm Input a number.
E) Signal at 1.22 ppm Input a number.
F) Signal at 0.91 ppm Input a number.

Aplate clutch has a single pair of mating friction surfaces 250-mm od by 175-mm id. the mean value of the coefficient of friction is 0.30, and the actuating force is 4 kn. a) find the maximum pressure and the torque capacity using the uniform-wear model. b) find the maximum pressure and the torque capacity using the uniform-pressure model.

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?
