Answer:
Explanation:
Given that,
Magnetic force acting on an electron,
The magnitude of the magnetic field,
We need to find the magnitude of the velocity. We know that the magnetic force is given by :
Where
v is the velocity
So,
So, the magnitude of velocity is.
Hello,
This is true. Net force can be calculated using the equation F = ma, where f is net force, m is mass, and a is acceleration. Simply multiply mass and acceleration to obtain the net force being exerted on the object.
True
Hope this helps!
Answer:
Resonance depends on objects, this may happen for example when you play guitar in a given room, you may find that for some notes the walls or some object vibrate more than for others. This is because those notes are near the frequency of resonance of the walls.
So waves involved are waves that can move or affect objects (in this case the pressure waves of the sound, and the waves that are moving the wall).
this means that the waves are mechanic waves.
Now, in electromagnetics, you also can find resonance frequencies for electromagnetic waves trapped in things called cavities, but this is a different topic.
