If a wave has a wavelength of 9 meters and a period of 0.006, what is the velocity of the wave?
lana66690 [7]

<u>Answer</u>

D. 1,500 m/s

<u>Explanation</u>

the wave equation states that,

V = λf

Where V ⇒ Velocity

λ ⇒ wavelength

f ⇒ Frequency

F = 1/T

Where T ⇒ period

F = 1/0.006

= 166.667

∴ V = 9 × 166.667

= 1,500 m/s

True or false: Decreased output from the vasomotor center allows arterioles and veins to constrict.
wolverine [178]
<h3><u>Answer;</u></h3>

The above statement is False

<h3><u>Explanation;</u></h3>
  • Decreased output from the vasomotor center allows arterioles and veins to dilate.
  • The vasomotor center controls vessel tone or contraction of the smooth muscle in the tunica media.It is responsible for central regulation of cardiac electrical activity, myocardial performance, and peripheral vascular tone.
  • Changes in diameter affect peripheral resistance, pressure, and flow, which in turn affect cardiac output.
