A string along which waves can travel is 4.36 m long and has a mass of 222 g. The tension in the string is 60.0 N. What must be
lora16 [44]

Answer:

frequency is 195.467 Hz

Explanation:

given data

length L = 4.36 m

mass m = 222 g = 0.222 kg

tension T = 60 N

amplitude A = 6.43 mm = 6.43 × 10^{-3} m

power P = 54 W

to find out

frequency f

solution

first we find here density of string that is

density ( μ )= m/L ................1

μ = 0.222 / 4.36  

density μ is 0.050 kg/m

and speed of travelling wave

speed v = √(T/μ)       ...............2

speed v = √(60/0.050)

speed v = 34.64 m/s

and we find wavelength by power that is

power = μ×A²×ω²×v  /  2     ....................3

here ω is wavelength put value

54 = ( 0.050 ×(6.43 × 10^{-3})²×ω²× 34.64 )   /  2

0.050 ×(6.43 × 10^{-3})²×ω²× 34.64 = 108

ω² = 108 / 7.160  × 10^{-5}

ω = 1228.16 rad/s

so frequency will be

frequency = ω / 2π

frequency = 1228.16 / 2π

frequency is 195.467 Hz

In your own words explain why the thickness and length of a wire could effect the flow of electrons​
agasfer [191]

Answer:

(you can use my exact words) The length and thickness would make it so that the electrons move differently than they would a shorter and thinner wire because with the wire being longer the electrons would have a longer trip and with the wire being thicker the electrons would be more spread out and move be able to move more freely

CALCULATE THE DECELERATION OF A RUNNER
AlexFokin [52]

Answer:

a =  \frac{ {v}^{2} -  {u}^{2}  }{2s}  \\ or \\  a =  \frac{v - u}{t}  \\ say \: a =  - 10m. {s}^{ - 2}  \\  \therefore \: deceleration =  - 10m. {s}^{ - 2}

How does something become charged using friction?​
KonstantinChe [14]

<u>Answer:</u>

"Where friction or rubbing results in the transfer of electrons between particles, objects can become negatively or positively charged."

<u>Explanation:</u>

The motion resistance of one moving object with respect to another is called as "Friction". It isn't a basic force, like gravity or electromagnetism. Alternatively, scientists believe it is the product of the electromagnetic attraction in two touching surfaces between charged particles.

The friction have formula:  

Friction force (<em>f </em>)  = coefficient of friction  × normal force (N)

For an instances when one ride a bicycle, an example of rolling friction is the contact between the wheel and the way.
