Answer:
As most economies witness rapid expansion, demand for power is projected to increase significantly. Though most economies have invested in fossil fuels, renewable and sustainable sources present great possibilities for cheap and reliable electricity. One energy resource that ranks among the top renewable and sustainable sources is tidal energy.
Tidal energy or tidal power is a form of renewable energy obtained due to alternating sea levels. The kinetic energy from the natural rise and fall of tides is harnessed and converted into electricity. Tides are caused by the combined gravitational forces of the moon, sun, and earth. However, tides are influenced most by the moon. The moon’s gravitational force is so strong that it tugs the ocean into a bulge. The high and low tides create tidal currents, which are essential in the generation of this kind of energy, mostly prevalent in coastal areas.
Arete is a sharp ridge separating two cirques or glacial vallies found in mountain regions. It is French for fishbone or the backbone of a fish, spine
The simplest, obvious category is " <em>Satellites</em> " .
But there's a lot of good reason to call it "Component of Binary Planet" .
As a fraction of the size and mass of its planet, our moon is the largest in the solar system.
Several writers have pointed out that an alien astronomer studying our solar system might describe the 3rd body from the Sun as a "Binary planet".
Question is missing:
"What is the gravitational force between the Sun and Jupiter?"
Answer:
Explanation:
The gravitational force between two objects is given by
where
is the gravitational constant
m1, m2 are the masses of the two objects
r is the separation between the objects
In this problem, we have
is the mass of the sun
is the mass of Jupiter
is their separation
Solving the equation, we find
A red light means to stop. If you are turning from a two-way road or onto a two-way road, then you are NOT allowed to reverse your car If you can't do it
Red is typically used to indicate danger or warning, and on traffic lights, it indicates a potential hazard ahead and, as a result, serves as a signal for drivers to stop. If the traffic light turns red while you are already at a junction, you must move swiftly to the opposite side to avoid a potential accident with oncoming traffic.
If the traffic light has turned red as you approach the junction and you are just entering it, you must stop. Unless there is a sign clearly telling you not to turn left at the red light, you may do so. Give way to people and cars coming from other directions when turning.
