The first law of thermodynamics is usually written as dq=dw+du. you need to look at the signs carefully; some other disciplines
Bad White [126]
<span>The first law of thermodynamics is follows the quantity dQ = dW + dU where Q is the heat flow, W is the work and U is the internal energy. Only the internal energy is a state function where it means that it does not follow a specific path to arrive at a certain number. Whereas the work and heat are not state functions and they follow a specific path or process in order to arrive at a certain number. An example would be  if y</span>ou are given 2,380 J of energy to do work as 12,900 J and you are to find the internal energy. Apply the equation above:

Q = U + W
2,380 J = U + 12,900 J
U = 15,280J.

Which of the following best explains why the Inuit principally relied on hunting for survival? Group of answer choices A.Tundra
Allushta [10]

Answer:

Option (A)

Explanation:

The Inuits refers to those people that live in the Arctic region, such as Greenland, the northern region of Canada, as well as Alaska. The region in which they live can be considered as tundra, which is characterized by the presence of low temperature, dry wind, shorter duration of seasons, and lack of vegetation. This type of region is found in the polar and near-polar areas and in the high altitude areas.

The climate of tundra is very cold, and there occurs the layer of permafrost in the soil, and it does not provide the essential conditions for the growth of plants. The growth of crops is hindered by the shorter season, lack of sunlight and low precipitation.

This is why the Inuits are dependent on hunting for heir survival

Thus, the correct answer is option (A).
