Nonrenewable energy resources, like coal, nuclear, oil, and natural gas, are available in limited supplies. This is usually due to the long time it takes for them to be replenished. Renewable resources are replenished naturally and over relatively short periods of time. (solar energy, wave energy, etc)
Answer:
All of the planets move around the Sun in a direct (eastward) direction, but three of them (Venus, Uranus and Pluto) rotate in a retrograde (westward) direction, and are said to have a retrograde rotation. Do not confuse revolution, or motion around an orbit, with rotation, or turning about an axis.
Explanation:
Yea it is right 1950. Geography !
Answer: 36 months
Explanation:
The earth complete its orbit in 12 months
While the superior planet complete its orbit in 18 months
Therefore since they are moving in the same direction, both planet will meet at the point where the superior planet and earth completes x and x+1 number of orbits.
Where x is a constant that represents number of orbits.
The period y when they both complete x and x+1 orbit respectively are;
y= 18x and y = 12(x+1)
Equating the two equations, we have,
18x=12(x+1) = 12x + 12
18x-12x= 12
x= 12/6= 2
Since x= 2
y= 18x=18×2= 36months
y= 36 months
Goodluck...
