Help! I’ll give brainliest! If an observer is hearing a rising pitch, that means that the frequency of the waves in their positi

False because if it's getting higher/rising that doesn't mean it's getting lower (my opinion Idk if correct, it's just common sense.)

The statement is false.

Pitch of a sound wave is the quantity that determines how high or low a sound is when it is perceived. A higher pitch corresponds to a higher frequency.

There could be another case, the Doppler's effect. the source or the observer might be moving towards the other. In such cases, the frequency of the sound wave does not change but it appears to be rising due to the motion.

the density of maple wood is about 755.kg/m. What is the mass of a solid piece of maple that has a volume 640.cm?
jenyasd209 [6]

I believe that the correct given values are:

density = 755 kg/m^3

volume = 640 cm^3

 

First let us convert volume to m^3 units.

volume = 640 cm^3 * (1 m / 100 cm)^3 = 6.4 x 10^-4 m^3

 

so the mass is:

mass = 755 kg/m^3 * (6.4 x 10^-4 m^3)

<span>mass = 0.4832 kg = 483.2 g</span>

What is the primary ingredient of power yoga?
LuckyWell [14K]
The primary ingredient of power yoga was said to be heated. The heat makes the power yoga so particularly effective as a physical therapy. The heat is primarily used in shaping glasses to any figures that the person may want to. Power yoga can practically provide more space for fluids to carry the nutrients and remove toxins

By Faraday’s Law, if a conducting wire of length ℓ meters moves at velocity v m/s perpendicular to a magnetic field of strength
sasho [114]

Answer

given,

conducting wire  length =  ℓ m = 0.5

moves at velocity =  v m/s = v ( t ) = 4 t + 9

magnetic field strength = B  = 2 T

V = − B ℓ v

V = - 2 × 0.5 × v

V = - v

a) \dfrac{dV}{dv} = \dfrac{d(-v)}{dv}

   \dfrac{dV}{dv} = -1

b) given

    v ( t ) = 4 t + 9

    V = (-1)(4t + 9)

   \dfrac{dV}{dt} = \dfrac{d((-1)(4t + 9))}{dt}

   \dfrac{dV}{dv} = -4
