The Solar electricity source of
energy comes from the sun’s rays. It is more often in the form of a panel known
as the solar panel. It has a photovoltaic system that generates and supplies
energy in commercial and residential areas. Countries are using this type of
electricity to save electric-induced power.
When an earthquake strikes usually seismic waves carry the energy outward (a.) With the greatest power at the focus and as the seismic waves travel outward they become more and more weak until they disappear.<span />
Answer:
As a substance gains heat energy (in the case of the lava lamp, heat is transferred from the hot light bulb to the lava), it becomes less dense than the surrounding liquid ), causing the substance to rise.
Answer:
You have a displacement of 5 units to the right.
Explanation:
First you go three to the right which lands on the 3 mark. Then you move it 4 to the left which substracts 4, landing the object at -1. Finally you move 6 to the right, and you finish at marker 5. Since displacement is not total distance but just final distance from the start point directly to end point, it is only a displacement of 5.
The refractive index of a medium is independent of (not related to) the angles of incidence or refraction. It's just a property of the medium. <em>(D)</em>
