Answer:
The actual work output is 1,125 kilojoules.
Explanation:
Energy efficiency is defined as the efficient use of energy. An appliance, process, or facility is energy efficient when it consumes less than the average amount of energy to perform an activity. Then, energy efficiency is the ratio between the amount of energy used in an activity and the amount expected to be carried out.
Efficiency is calculated as:
efficiency = output / input
Where output is the amount of mechanical work (in watts) or energy consumed by the process (in joules), and input (input) is the amount of work or energy that is used as input to carry out the process.
In this case:
- Efficiency always has a value between 0 and 1. In this case, efficiency=0.15
- output=?
- input= 7500 kilojoules
Replacing:
0.15=output/7500 kilojoules
Solving:
Output=0.15* 7500 kilojoules
output=1,125 kilojoules
<u><em>The actual work output is 1,125 kilojoules.</em></u>
Answer:
When the northern hemisphere experiences autumn, the southern hemisphere experiences <u><em>spring</em></u>
Explanation:
When the northern hemisphere experiences autumn, the southern hemisphere experiences <u><em>spring</em></u>
This is due to the equinoxes. An equinox is an event that occurs twice a year. During these seasons all areas of the Earth's surface experience an equal amount of daylight and darkness. The sun is on the equator line, so the day and night in both hemispheres have the same duration. At that time the part of the Earth closest to the Sun is the equator.
The shape of the Earth means that while the spring equinox is experienced in the northern hemisphere, the autumn equinox is entered in the southern hemisphere.
