mode of building, construction, or organization; arrangement of parts, elements, or constituents: a pyramidal structure. something built or constructed, as a building, bridge, or dam. a complex system considered from the point of view of the whole rather than of any single part: the structure of modern science.
Answer:
Explanation:
The beam of positively charged particles would not be deflected if the electric force acting on them is equal to the magnetic force:
where
q is the charge of the particles
E is the magnitude of the electric field
v is the speed of the particles
B is the intensity of the magnetic field
is the angle between the direction of v and B
Since the beam of particles travels perpendicular to the magnetic field, we have . So, we can rewrite the equation as
where
Substituting into the formula,
Answer:
The statement is true
Explanation:
The complete question is
Light bends when it changes the medium because the dielectric permittivity of the material makes the path more hard to penetrate
True or False
Solution
The given statement is true as it is the dielectric permittivity of the material which does not allow light to pass through it easily.
The medium decrease the amplitude of light and hence induces change in direction without altering its velocity or frequency.
Answer:
It comes from the sun unevenly heating the earth. Creating warm and cool spots.
