F = qE + qV × B
where force F, electric field E, velocity V, and magnetic field B are vectors and the × operator is the vector cross product. If the electron remains undeflected, then F = 0 and E = -V × B
which means that |V| = |E| / |B| and the vectors must have the proper geometrical relationship. I therefore get
|V| = 8.8e3 / 3.7e-3
= 2.4e6 m/sec
Acceleration a = V²/r, where r is the radius of curvature.
a = F/m, where m is the mass of an electron,
so qVB/m = V²/r.
Solving for r yields
r = mV/qB
= 9.11e-31 kg * 2.37e6 m/sec / (1.60e-19 coul * 3.7e-3 T)
= 3.65e-3 m
Answer:
The correct option is
a. The inductive reactance is doubled and the capacitive reactance is halved
Explanation:
For a series RLC circuit, is a resonant circuit such that the impedance, Z, is minimum at the resonance frequency
Also we have that the capacitive reactance
, is given as follows;

Where;
ω = Angular frequency = 2πf
Where;
f = The frequency in the circuit

The inductive reactance is also given as follows;

Therefore, when the circuit frequency doubles, the inductive reactance doubles and the capacitive reactance halves
The magma is heated and becomes less dense by the core moving it toward the crust.
Option D.
<u>Explanation:</u>
Magma is a form of molten rock which might be partially molten or might be fully molten. Magma consists of silicate liquid.
This molten part of the rock is either ejected in the form of lava or this molten rock might move from upper layer of Earth to the lower layer of Earth. The crystals which are not molten which get transported into the magma, form bubbles and get separated.
James Clerk Maxwell laid the foundation for the discovery of electromagnetism. True
