Answer:

C.85

Explanation:

Use the equation:

v= fλ ( v=wave speed, f= frequency, λ= wavelength)

4700= 55×λ

λ=4700÷55 =85.45 =85(approximately)

Explain how a book can have energy even if it is not moving.
frutty [35]
Can something have energy even if it's not moving?
All moving objects have kinetic energy. When an object is in motion, it changes its position by moving in a direction: up, down, forward, or backward. ... Potential energy is stored energy. Even when an object is sitting still, it has energy stored inside that can be turned into kinetic energy (motion).


Does a book at rest have energy?
A World Civilization book at rest on the top shelf of a locker possesses mechanical energy due to its vertical position above the ground (gravitational potential energy).



Does a book lying on a table have energy?
The book lying on a desk has potential energy; the book falling off a desk has kinetic energy.

a violinist plays a note with a wavelength of 0.77955 m. if the speed of the sound is 343 m/s, what pitch is this note?
prisoha [69]
Answer: The pitch of the note is: 439.99 Hz


Explanation:

Since,

v = fλ

Therefore,
f =  \frac{v}{\lambda}

Where v = 343m/s
λ = <span>0.77955 m

Plug-in the values:

</span>f =  \frac{343}{0.77955}
<span>
f = 439.99 Hz(pitch)</span>

A hypothetical planet has a mass of one-half that of the earth and a radius of twice that of the earth. what is the acceleration
algol [13]
Let m = mass of earth 
<span>let r = radius of earth </span>
<span>let a = acceleration due to gravity on earth </span>
<span>G = constant (it doesn't change) </span>

<span>If you plug in the mass and radius of the new planet, you get </span>

<span>a = G (.5m)/(2r)^2 </span>
<span>a = 1/8 (Gm/r^2) </span>

<span>so the acceleration on the new planet is 1/8 what it is here.</span>
