phyiscs problem about interfernce of two radio waves?
Two coherent sources of radio waves, A and B, are positioned 5.00 meters apart. Each source emits waves with a wavelength of 6.00 meters. Consider points along the straight line connecting the two sou...
In the study of physics, what distinguishes a scalar from a vector?
In the study of physics, what distinguishes a scalar from a vector? A scalar is defined by a single numerical value, while a vector is characterized by both a magnitude and a direction. Scalars can be...
Displacement vectors of 3m and 5m in the same direction combine to make a displacement vector that is 2m?? How?? Why isn’t it 8m?
I have a question regarding displacement vectors. If I have two displacement vectors of 3 meters and 5 meters that are in the same direction, how can they combine to create a resultant displacement ve...
