Answer:
9.03 x 10³ m /s
Explanation:
magnetic field inside a solenoid
B = μ₀ n I , where μ₀ = 4π X 10⁻⁷ .
n is no of turns per unit length and I is current
so B₁ = 4π x10⁻⁷x 593 / 20.9 x 5.65 x 10²
201.5 x 10⁻⁴ T
B₂ = 4π x 10⁻⁷ x 343 / 19.1 x 1.37 x 10²
= 30.93 x 10⁻⁴ T
Net magnetc field
B₁ -B₂ = B = (201.5 - 30.93) x 10⁻⁴ T
B = 170.57 x 10⁻⁴ T
Now protons move in circular path of radius R in the magnetic field of B
B q v = m v² / R
v = B q R / m
= 170 .57 x 10⁻⁴ x 1.6 x 10⁻¹⁹ x 5.53 x 10⁻³ / (1.67 x 10⁻²⁷)
= 903.71 x 10
= 9.03 x 10³ m /s

Answer:
The mechanism of energy transport through a medium involves the absorption and reemission of the wave energy by the atoms of the material. When an electromagnetic wave impinges upon the atoms of a material, the energy of that wave is absorbed.
D =vt
since it has to go down and come back up, you must half the time in this problem.
d = (1498)(0.5•2.5)
d = 1872.5 m
Answer:
4347.8 m/s
Explanation:
It is given that the radius of the circular path traversed by proton and electron is same. Also, we know that magnitude of charge on an electron and proton is same. Magnetic field strength is same for both.
Take the ratio:
Answer:
The answer is B
Explanation:
The absorption happens when photons from light hit atoms and molecules, and they vibrate because of that specific interaction. Then the heat ejects from the object in the format of thermal energy.
