What is the environmental purpose of issuing hunting licenses?

The plain and opaque surface M has the following properties: gray and diffuse, with an absorptivity of 0.7 and an area of 0.5 m², maintained at a temperature of 500°C. Surface M is exposed to incoming radiant energy at a rate of 10,000 W/m². Calculate the energy absorbed per unit time. Subsequent parts, d to f, will also pertain to surface M.

A sedimentation basin with a 30-meter diameter and an average water depth of 3.0 meters treats a wastewater flow of 0.3 cubic meters per second. Calculate the overflow rate and detention time.

A resistor R = 1 kohm an inductor L = 1 mH and a capacitor C = 1 muFare used in a circuit which is driven by a voltage source v_s(t) = 10 sin(10^5 t + 45degree)(waming: note the input is a sine function not a cosine function.) What is the phasor corresponding to the voltage source? Express it in the polar form AZB and write your answer as "A B" without the quotation marks.

Which of the following describes the introduction of a speech? A) Where the speaker should go big B) Where the speaker recaps the main points C) All of the above

Which of these formulas is the equivalent of I=E/R?​

Saturated water at 25C enters a tank through a 10-cm diameter pipe at a velocity of 3 m/s. At the bottom of the tank, water exits at 6 m/s through a 5.25- cm diameter pipe. The depth of the water in the tank is 1.5 m. The tank has a diameter of 1.25 m and a height of 2.5 m. Water in the tank is also magically kept at 25C, which is the same to the surrounding temperature. Assume that pressures at inlet, outlet, and the surrounding are roughly the same and pressure effect is negligible.

Which of the following identifies the three main steps in the design process of an engineer?
