For the rotation in two dimensions, both energy, and angular momentum is quantized.  Select one: True False

A missile is fired and a radar on the ground shows that the missile follows the law of movement r(t) = 5 (V₁² +25' VP² +25² arctan ¹). Answer what is proposed below: (A)) Find the speed, acceleration and shaking of the missile. (B) Find the curvature and torsion of the missile trajectory in t = 2 (C) Find the mobile frame (T, N, B) in t = 1. (D) What is the length of the path traveled by the missile from its launch in t = 0 to its impact in t=10

Please solve this question in fluid mechanics

I got an answer of x = 89.4mm And a reynolds number of  1.09 * 10^5   Just want to confirm my math

An open cylindrical container containing liquid is spinning about its vertical axis such that the liquid undergoes rigid body rotation. Which of the following phenomena are correct? (1) The surface of the liquid is a curve with lowest point at the axis of rotation. There will be no shear stress. There will be no pressure stress. (iii) (A) (B) (C) (D) (i) and (ii) (i) and (iii) (ii) and (iii) All of the above The Energy Line (EL) and Hydraulic Gradient Line (HGL) are used to represent the condition in a pipe flow. Which of the following statements are correct? (1) The difference between EL and HGL is the velocity head. When Bernoulli equation is valid, the EL is constant and remains horizontal, but the HGL needs not necessary so. When there is a sudden contraction in the pipe flow, the HGL will drop. (A) (B) (C) (D) (i) and (ii) (i) and (iii) (ii) and (iii) All of the above

A block with a weight of 5 kg hanging from the ceiling attached to a spring is raised and then pulled downward. As it passes downward through the spring's unstretched position it has a speed of 10 m/s downward. If the spring has a stiffness of 5 N/m, determine the maximum position below the spring's unstretched position achieved by the block.

The buoy in the photograph can be modeled as a circular cylinder of diameter d and mass m. If the buoy is pushed down in the water, which has density ρ, it will oscillate vertically. Consider d = 1.2 m, m = 1060 kg, and surface seawater, which has a density of ρ = 1027 kg/m3.       NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part.     Determine the frequency of oscillation. (Round the final answer to four decimal places.)   The frequency of oscillation is  Hz.

Simplify the Navier–Stokes equation as much as possible for the case of incompressible hydrostatics, with gravity acting in the negative z-direction. Begin with the incompressible vector form of the Navier–Stokes equation, explain how and why some terms can be simplified, and give your final result as a vector equation.
