Answer:
Thin, aluminium and buried underground.
Explanation:
When it comes to electrification of a state or province, some characteristics of the wire to use must be considered. This would help to minimize and avoid power loss and wire burns.
i. The wire to use should be thin, and a quite number can be twisted one against the other so as to increase the surface area for heat dissipation.
ii. Aluminium wire is more preferable for this project. It has a high melting point, and reduces energy loss.
iii. Burying the wire underground through an insulator is the best choice, though expensive but would preserve the wire from external influence.
Answer:
physics, escape velocity is the minimum speed needed for an object to escape from the gravitational influence of a massive body. The escape velocity from Earth is about 11.186 km/s (6.951 mi/s; 40,270 km/h; 25,020 mph)[1] at the surface. ... [2] Speeds higher than escape velocity have a positive speed at infinity.
Answer:
a. When the parties have unequal bargaining power
c. When it covers public transportation
Explanation:
Exculpatory clauses are often found in agreements between a company and a consumer when the activity is in danger, such as at a fitness center or ski resort. The company wants the consumer to understand the risk involved and to avoid lawsuits, so it includes a disclaimer in its contract. These clauses are used to limit liability, so they are not enforced when the parties have unequal bargaining power and when covering public transport.
We can confirm that the difference between a comet and an asteroid lies in their compositions and physical characteristics <u>derived from those compositions</u>.
As stated in the question, the main difference between an asteroid and a comet is their compositions, meaning the materials from which they form.
Asteroids are rocky objects which a heavy metal composition, while comets tend to be made of dust, ice, and <em><u>some </u></em>rocky material. Some extra differences include:
- Comets reflect a steady amount of light (because of their ice composition)
- Asteroids will <em><u>reflect light at random intervals due to some metals that may be present on their surface</u></em>
- Comets tend to have a tail made of water from the melting ice when reflecting sunlight.
Therefore, we can confirm that the main difference between asteroids and comets is their compositions, which lead to distinct physical characteristics.
