The tilt can lead to darkness, for the sun is away from the Earth. The sun will reach the Earth at different times, and if it is further away, it will cause the temperature to change.
Answer:
Energy production requires the setting up of a complete interconnected chain from generation of energy from the root source of the energy to the storage of the generated energy and the eventual utilization of the energy when required
Solar energy, indirectly, continues to be the main source of energy, however, the direct use of solar energy to power the systems we use in our everyday life, require the development of technologies, such as high efficiency solar cells, means of energy storage, and compatible efficient energy usage which are industrial areas that are seeing good progress but in which the current developed equipment are expensive to produce, and due to their efficiency, are undergoing further research and development
Therefore, due to the continuous increasing improvement in solar technology which can observed, the use of the produced energy through solar is evolving, and therefore, will continue to play a continuously increasing but lower role compared to other sources of energy which have been developed to satisfactory level that can drive an industry, considering the financial investment involved

Answer:
<em>She raised approximately 4 meters as she crosses the bar</em>
Explanation:
<u>Energy Conservation</u>
In the absence of air resistance and any other energy-absorbing events, the total mechanical energy is conserved. Recall the mechanical energy is the sum of the gravitational potential energy and the kinetic energy:
When our athlete is at the ground level her height is 0, thus she has only kinetic energy given by the speed she's at when starting the jump:
Later when she's directly above the bar, she has both energies since some speed remains at a certain height h we must calculate. The mechanical energy is
Equating both energies
Simplifying by m and rearranging
Solving for h
She raised approximately 4 meters as she crosses the bar
Answer:
Fusion and fission are similar in that they both release large amounts of energy. Nuclear fusion is a process in which two nuclei join to form a larger nucleus. Nuclear fission is a process in which a nucleus splits into two smaller nuclei.

Answer:
Explanation:
Given
Total time=27 min 43.6 s=1663.6 s
total distance=10 km
Initial distance
time taken=25 min =1500 s
initial speed
after 8.13 km mark steve started to accelerate
speed after 60 s
distance traveled in 60 sec
time taken in last part of journey
distance traveled in this time
and total distance
