Answer:
C. Both A and B
Explanation:
Fuses are rated by the amperage they can carry before heat melts the element. The fuse is ideal for protection against short circuits. Short circuits produce enough amperage to vaporize a fuse element and break connection in one cycle of a 60-cycle system.
Specifically, the voltage rating determines the ability of the fuse to suppress the internal arcing that occurs after a fuse link melts and an arc is produced.
Answer:
student attach a save block to a horizontal spring so that the block spring system will oscillator with the block spring system released from rest horizontal position that is not the systems equilibrium position well this question regards about the energy used the answer may be 0.73 Joel ok you just try it ok verified
Explanation:
apply applied the potential energy value mean the formula MGH write it means what mass into gravitation in to height
Good i’m tired how about you
I think what’s wrong is that the paper clip isn’t connecting to the other thing on the bottom
Answer:71 dB
Explanation:
Given
sound Level ![\beta _1=124 dB](https://tex.z-dn.net/?f=%5Cbeta%20_1%3D124%20dB)
distance ![r_1=5.01 m](https://tex.z-dn.net/?f=r_1%3D5.01%20m)
From sound Intensity
![\beta =10dB\log (\frac{I_1}{I_0})](https://tex.z-dn.net/?f=%5Cbeta%20%3D10dB%5Clog%20%28%5Cfrac%7BI_1%7D%7BI_0%7D%29)
![124=10dB\log (\frac{I_1}{I_0})](https://tex.z-dn.net/?f=124%3D10dB%5Clog%20%28%5Cfrac%7BI_1%7D%7BI_0%7D%29)
![12.4=\log (\frac{I_1}{I_0})](https://tex.z-dn.net/?f=12.4%3D%5Clog%20%28%5Cfrac%7BI_1%7D%7BI_0%7D%29)
![I_1=(1\times 10^{-12})\times 10^{12.4}](https://tex.z-dn.net/?f=I_1%3D%281%5Ctimes%2010%5E%7B-12%7D%29%5Ctimes%2010%5E%7B12.4%7D)
![I_1=2.51 W/m^2](https://tex.z-dn.net/?f=I_1%3D2.51%20W%2Fm%5E2)
we know Intensity ![I\propto ^\frac{1}{r^2}](https://tex.z-dn.net/?f=I%5Cpropto%20%5E%5Cfrac%7B1%7D%7Br%5E2%7D)
![I_1r_1^2=I_2r_2^2](https://tex.z-dn.net/?f=I_1r_1%5E2%3DI_2r_2%5E2)
![I_2=I_1(\frac{r_1}{r_2})^2](https://tex.z-dn.net/?f=I_2%3DI_1%28%5Cfrac%7Br_1%7D%7Br_2%7D%29%5E2)
![I_2=2.51\cdot (\frac{5.01}{2.25\times 10^3})^2](https://tex.z-dn.net/?f=I_2%3D2.51%5Ccdot%20%28%5Cfrac%7B5.01%7D%7B2.25%5Ctimes%2010%5E3%7D%29%5E2)
![I_2=1.24\times 10^{-5} W/m^2](https://tex.z-dn.net/?f=I_2%3D1.24%5Ctimes%2010%5E%7B-5%7D%20W%2Fm%5E2)
Sound level corresponding to ![I_2](https://tex.z-dn.net/?f=I_2)
![\beta _2=10\log (\frac{I_2}{I_0})](https://tex.z-dn.net/?f=%5Cbeta%20_2%3D10%5Clog%20%28%5Cfrac%7BI_2%7D%7BI_0%7D%29)
![\beta _2=10\log (\frac{1.24\times 10^{-5}}{1\times 10^{-12}})](https://tex.z-dn.net/?f=%5Cbeta%20_2%3D10%5Clog%20%28%5Cfrac%7B1.24%5Ctimes%2010%5E%7B-5%7D%7D%7B1%5Ctimes%2010%5E%7B-12%7D%7D%29)
![\beta _2=70.93\approx 71 dB](https://tex.z-dn.net/?f=%5Cbeta%20_2%3D70.93%5Capprox%2071%20dB)
