Answer:

Teniendo dos tuberías, una hueca y otra sólida, con la misma masa, radio y longitud, ambas poseen la misma rapidez angular, entonces el cuerpo hueco tendrá mayor energía cinética rotacional que la tubería sólida, esto es debido a que el tubo hueco tiene mayor inercia rotacional.

La ecuación de energía rotacional viene dada como:

Er = (1/2)·I·ω

De esta manera tenemos que el tubo hueco tiene mayor inercia rotacional que el tubo sólido, por ende, mayor energía.

Magnetic resonance imaging needs a magnetic field strength of 1.5 T. The solenoid is 1.8 m long and 75 cm in diameter. It is tig
TEA [102]

Answer:I=2.27\times 10^3 A

Explanation:

Given

Magnetic Field Strength B=1.5 T

Length of solenoid L=1.8 m

Diameter of Solenoid D=75 cm

diameter of wire d=1.90 mm

No of turns N=\frac{Length\ of\ solenoid}{diameter\ of\ wire}

N=\frac{1.8}{1.90\times 10^{-3}}=947.36 turns

Magnetic Field is given by

B=\frac{\mu _0NI}{L}

where \mu _0=magnetic\ permeability\ of\ free\ space=4\pi \times 10^{-7}

I =current

Thus I=\frac{BL}{\mu _0N}

I=\frac{1.5\times 1.8}{4\pi \times 10^{-7}\times 947.36}

I=2270 A

I=2.27\times 10^3 A
