The man stands a distance (d = 20 m) from the wall and throws a ball at it with a speed (vo 16 m/s). Determine the angle = (0) at which he should release the ball so that it strikes the wall at the highest point possible. What is this height (h)? The room has a ceiling height (h₂ = 6 m ) and the value of ( h₁ = 1.3 m ).​

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

Consider a beam traveling through diamond and impinging upon the diamond-air interface. the critical angle of incidence for total internal reflection to occur is closest to the following value: select one: a)-22.50° b)-23.85 c)-24.30 d)-23.40° e)-none of the above

Steam enters a turbine at steady state at 2 mpa, 360°c with a velocity of 100 m/s. saturated vapor exits at 0.1 mpa and a velocity of 50 m/s. the elevation of the inlet is 3 m higher than at the exit. the mass flow rate of the steam is 15 kg/s, and the power developed is 7 mw. let g 9.81 m/s^2. determine: a)-the area at the inlet, in m^2 b)-the rate of heat transfer between the turbine and surroundings, in kw c)-draw a p-v diagram for this process.
