Answer:
378 Hz
Explanation:
When source of sound moves away from stationary listener
f' = f x V / ( V + Vs)
f' = 600 x 340 / ( 340 + 200)
f' = 204000/540
f' = 378 Hz

Thats to fast
Answer:
R = 11.8 ohms
Explanation:
Formula
R = R_ref[1 + a(T - T_ref)]
Givens
- R_ref = 10 ohms
- T_ref = 20oC
- T = 65oC
- a = 0.004
- R = resistance at 65oC = ???
Solution
R = 10*[1 + 0.004(65 - 20)]
R = 10*[1 + 0.004(45)]
R = 10*[1 + 0.18]
R = 10*(1.18)
R = 11.8 ohms
Be sure you understand not to add the 1 and 0.004 together. You don't get 1.004 at any point of the solution. If you do, you won't know what to do (exactly) with the 45.
RDA stands for Recommended Daily Allowance. To determine the amount needed of a certain adult per day, we simply multiply the mass of the adult to the value of RDA. For this case, we do as follows:
Daily requirement = 12 mg/kg ( 78 kg ) = 936 mg of lysine = 936000 g
