7. () Figure 2 shows a mass P of 2.6kg, freely suspended by two strings AP and BP, fixed at two points
A and B on the same horizontal plane. AB is 1.3 m. BP is perpendicular to AP, BP is an elastist
string of natural length im, while AP is an inelastic string of natural length 0.5m. P hangs igles
equilibrium when BP is 1.2m.
Taking g = 10ms 2 find
(a) the tension in each of the strings
(b) the modulus of elasticity of BP.

Air initially at 0.75 bar, 1000 k, and occupying a volume of 0.12 m^3 undergoes two processes. process 1-2: the air is compressed isothermally until the volume is halved. process 2-3: the air undergoes a constant pressure process until the volume is halved again. assume ideal gas behavior. a) determine the mass of the air, in kg. b) the work and the heat transfer for each of the two processes, in kj. (100 kj = 1 bar . m^3)

Ascientist notices that an oil slick floating on water when viewed from above has many different colors reflecting off the surface, making it look rainbow-like (an effect known as iridescence). she aims a spectrometer at a particular spot and measures the wavelength to be 750 nm (in air). the index of refraction of water is 1.3
