Answer:
48kg
Explanation:
i could be wrong if i am srry
(1500 rev/min)(min / 60 s) / (3.0 s) = 8.33 rev/s²
<span>(B) </span>
<span>(1/2)(8.33 rev/s²)(3.0 s)² = 37.5 rev </span>
<span>(C) </span>
<span>(1500 rev/min)(min / 60 s)[2π(0.12 m) / rev] = 18.8 m/s</span>
Answer:
The speed of the wave is 
Explanation:
Given that,
Frequency = f
String length = l
We need to drive a formula of the speed of the wave
Using formula of fundamental frequency

We know that,


Where, v = speed of wave
= wavelength of the wave
f = frequency
The speed of the wave is

Hence, The speed of the wave is 
Matter is a thing. ex: paper. notice how paper can be written on. notice how it is ...well, THERE. now notice light. the light is not atoms. it is electricity that does weird stuff to create a big enough source of energy to be a source of light. sorta like fireflies
