Answer:
Electric current can best be induced in a wire by moving a magnet up and down near the wire is the correct answer.
Explanation:
Electric current is the flow of electron that carries the negative charge in the electric circuit.
Electric current induced in the wire through:
- Electric current is induced in the wire when the magnet moves in and down of the wire that is connected to a very high resistance voltmeter and when we move the magnet up and down the magnetic flux gets change and these changes produce induced current
- When the coil of wire is put in the magnetic field which is changing then the current will be induced in the wire.
Answer:
1) v = 2.20 10⁵ m / s
, 2) r = 4.86 10⁻³ m, r = 4.92 10⁻³ m
Explanation:
1) A speed selector is a section where the magnetic and electrical forces have opposite directions, so
q v B = q E
v = E / B
V = E s
E = V / s
v = V / s B
v = 148 / (0.0016 0.42)
v = 2.20 10⁵ m / s
2) when the isotopes enter the spectrometer, we can use Newton's second law
F = m a
Acceleration is centripetal
a = v² / r
q v B = m v² / r
r = m v / qB
The mass of uranium 235 is
m = 3.903 10⁻²⁵ kg
The radius of this isotope is
r = 3,903 10⁻²⁵ 2.20 10⁵ / (92 1.6 10⁻¹⁹ 1.2)
r = 4.86 10⁻³ m
The mass of the uranium isotope 238 is
m = 238 a = 238 1.66 10-27 = 395.08 10-27 kg
The radius is
r = 395.08 10⁻²⁷ 2.20 10⁵ / (92 1.6 10⁻¹⁹ 1.2)
r = 4.92 10⁻³ m
Answer:
Atacama Large Millimeter/Submillimeter Array (ALMA) Observatory's primary goal is to provide a radio telescope array that will allow scientists to observe and image galaxies out to the edge of the universe, and stars and planets in their formative stages with unprecedented clarity.
Explanation:
Answer:
Newtons
Explanation:
Its units are newtons because force has both magnitude and direction.
Answer:
1 m/s²
Explanation:
a = ∆v/t = (55 - 25)/30 = 30/30 = 1 m/s²
