Answer:
Explanation:
Direction of velocity of electromagnetic wave is given by the formula
E = E j ( vector form )
B = - Bi ( vector form )
Direction of velocity = direction of vector E X B
= E X B
= E j x -Bi
= - EB -k
v = EBk
So the direction of velocity will be along z direction.
Wavelength = Speed / Frequency = 340/200= 1.7m
Answer:

Explanation:
Given that acceleration of the airplane is


initial velocity is given as


now we have displacement in x direction given as



Displacement along y direction is given as



so the magnitude of the displacement is given as



Most pictures used as the milky way are actually just pictures of other galaxies (such as Andromeda) that we just figure are similar enough to ours.
