A charged particle moving in a magnetic field experiences a force equal to:
Thus, the magnitude of the force that the proton experiences is given by:
The magnetic field is perpendicular to the proton's velocity, therefore, we have 
. Replacing the given values, we obtain:
Answer:
option D
Explanation:
given,
increase the intensity by factor of 9
I₁ = I₀
I₂ = 9 I₀
now,
A₂ = 3 A₁
hence, amplitude increase with the factor of 3
so, the correct answer is option D
Answer: C Heat Transfer, E Addition of Volatiles and A Decompression
Explanation:
- Decompression melting takes place within Earth when a body of rock is held at approximately the same temperature but the pressure is reduced.
Plate Tectonics cause most earthquakes.
