Answer:
Poynting vector oscillate at a frequency of 2omega
Explanation:
This is because The poynting vector is proportional to the cross product of electric and magnetic field vectors. So Because both fields oscillate sinusoidally with frequency w, trigonometric identities show that their product is a sinusoidal function of frequency of 2w.
Forces are by the cable, gravity and normal force by the incline.
The correct answer is North & South poles attract each other. This is because opposites attract. If it were a north & north pole they'd repel each other, same if it were a south & south pole. This is because each magnetic field has a way of attracting two opposite poles (north to south, south to north).
Answer:
Explanation:
Lithification is the process by which sediments compact under the influence of pressure and the sediments become rocks. This process limits the porosity by destruction of porosity by compaction and cementation.
Sandstone is clastic sedimentary rock that forms by the process of lthification which involves the compaction and cementation of sand grains.
