Problem 2 (20 points): A steady, incompressible jet of water (jet 1) aligned with the horizontal with cross-sectional area $A_1 = 0.015 m^2$ and uniform velocity magnitude $V_1 = 10 m/s$ strikes a stationary block and splits into 2 jets (jet 2 and jet 3) as shown. The upper jet (jet 3) exits the block with a uniform velocity magnitude $V_3 = 10 m/s$ at an angle $\theta$ above the horizontal and has cross-sectional area $A_3 = 0.008 m^2$. The lower jet (jet 2) is aligned in the $-y$ direction with a uniform velocity magnitude $V_2 = 10 m/s$ and has cross-sectional area $A_2$. It is known that the net force acting on the block by the jets is equal to zero in the $y$-direction. Assume that the body forces are negligible, and the same uniform atmospheric pressure acts everywhere on the jets and the block. The density of water is $1000 kg/m^3$. a. Determine the cross-sectional area of jet 2, $A_2$. b. Determine the angle $\theta$. c. Calculate the horizontal force acting on the block by the jets and clearly indicate its direction (left or right).

Question 26 (2 points) Saved Which one of the following statements is true with regard to REM sleep? Question 26 options: REM sleep makes us roughly 50% of the normal sleep time for the average person During this phase of sleep, extremely variable and high amplitude EOG patterns occur. During this phase of sleep, sleep spindles form in the EEG response. In this stage, the individual drifts in and out of sleep and can be easily wakened.
