Build your paper cup telephone system?

Physics
1 answer:
Burka [1]1 year ago
6 0

To Build your paper cup telephone system do the following:

Two cups, some inelastic string, thread, or fishing line, two paper clips, and a pencil or sewing needle are needed to make a paper cup phone.

Use a pencil or sewing needle to make a hole in the bottom of each cup, then thread a string through each hole to make a paper cup phone.

To keep the thread from coming away from the cups, secure each end with a paper clip. One person should speak into one cup, and you should listen through the other.

Pull the string taut. With the cups, you can talk to someone up to 100 feet away.

A string phone functions quite similarly to a landline. Talking into the cup causes the bottom to vibrate as sound waves are transmitted within the cup by your voice.

The other cup's bottom receives the vibrations that are transmitted to the string, across it, and into it. The second cup vibrates as a result of the sound waves transmitting your voice's audio.

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>

If Earth's mass was cut in half, what would happen to your mass? Group of answer choices
Alex777 [14]

Answer:

nothing, mass is not affected by gravitational force

Explanation:

Weight is the gravitational force a planet exerts on a mass on the surface.

It is the product of the mass of an object with the gravitational acceleration that the planet produces.

The weight is the gravitational force

W=mg

where,

m = Mass of the object

g = Acceleration due to gravity = 9.81 m/s²

Mass is the property that matter has which opposes the force being applied to it. It is intrinsic to the object itself and does not change according to the gravitational force. But, the weight changes.

Neporo4naja [7]

Answer:

0.0170m or 1.70cm

Explanation:

L=(μ₀*N^2*A)/(l)

N=x/2*pi*r so r=x/2*pi*N

A=pi*r^2=(pi*x^2)/(4*pi^2*N^2)

L=(μ₀*N^2*A)/(l)=(μ₀*N^2*pi*x^2)/(4*pi^2*N^2*l)=(μ₀*x^2)/(4*pi*l)

l=(μ₀*x^2)/4*pi*L)=[(4*10^-7)*(1.15m)/4*pi*2.47*10^-6H)=0.0170m or 1.70cm

Hope this helps. Any questions please feel free to ask. Thanks!

Which features on mars point to the possibility of liquid water on the planet?
Stells [14]
     In 2011 NASA researchers identified features on Mars known as Recuring Slope Lineae ( or RSL ). RSL are relatively dark and narrow features.They are thought to be a signs of salty liquid water on Mars. One hypothesis for RSL formation is that they form when underground bodies of salty water leak into the surface.
   Answer: Recuring Slope Lineae.
