A field test is used to measure the density of crude oil recovered during a fracking*operation. The crude oil recovered is mixed with brine. The oil and brine mixture are placed in an open tank and allowed to separate. After separation, a 1.0-m layer of oil floats on top of 0.55 m of brine. The density of the brine is 1030 kg/m3and the pressure at the bottom of the tank is 14 kPa gage. Find the density of the oil.

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 710 n/m. it is initially at rest on an inclined plane that is at an angle of θ = 23° with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is μk = 0.19. in the initial position, where the spring is compressed by a distance of d = 0.16 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. a) what is the block's initial mechanical energy? b) if the spring pushes the block up the incline, what distance, l, in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.
