Answer:
38 m
Explanation:
Number of turns=N=100
Magnetic field=B=0.50 T
Frequency of the generator=f=60 Hz
Rms value of emf=![E_{rms}=120 V](https://tex.z-dn.net/?f=E_%7Brms%7D%3D120%20V)
We have to find the length of the wire from which the coil is made.
Peak value of emf=![E_0=E_{rms}\sqrt 2=120\times \sqrt 2=169.7 V](https://tex.z-dn.net/?f=E_0%3DE_%7Brms%7D%5Csqrt%202%3D120%5Ctimes%20%5Csqrt%202%3D169.7%20V)
Length of wire=![4\sqrt{\frac{NE_0}{2\pi fB}}](https://tex.z-dn.net/?f=4%5Csqrt%7B%5Cfrac%7BNE_0%7D%7B2%5Cpi%20fB%7D%7D)
Substitute the values
Length of wire=![4\times \sqrt{\frac{169.7\times 100}{0.50\times 2\pi\times 60}}](https://tex.z-dn.net/?f=4%5Ctimes%20%5Csqrt%7B%5Cfrac%7B169.7%5Ctimes%20100%7D%7B0.50%5Ctimes%202%5Cpi%5Ctimes%2060%7D%7D)
Length of wire=38 m
Hence, the length of wire from which the coil is made=38 m
The atoms furthest from the nucleus
An object can be at rest and still be in motion because the earth is always in motion.
Answer:
Explanation:
10. As a spaceship is moving toward Earth, an Earthling measures its length to be 325 m, while the captain on board radios that her spaceship's length is 1150 m. (c = 3.00 × 108 m/s) (a) How fast is the rocket moving relative to Earth? (b) What is the TOTAL energy of a 75.0-kg crewman as measured by (i) the captain in the rocket and (ii) the Earthling?
