The inclined plane is studied by mechanics and, to calculate it, we use Newton's Second Law.
Is a block of mass “m” supported by an inclined ramp at an angle? with respect to the horizontal plane. Despise the friction.
Forces acting on the body are: image 1
P: Force weight = P = m.g
Where: g = 9,8 m / s2
m = body mass given in kg.
FN: Normal reaction force to the plane.
When we neglect friction we notice that the body moves downwards. image 2
Answer:
- Gains from trade
- Consumer Satisfaction
- Greater Efficiency
- Growth Opportunities
Explanation:
According to Investopedia, specialization is a method of production where an entity focuses on the production of a limited scope of goods to gain a greater degree of efficiency.
A country can specialize on the production of a particular commodity or service that is peculiar to their part of the world giving them the opportunity to become very efficient and have more opportunities for growth. Some of the benefits of specialization in a country include;
- Economies of scale/ greater efficiency: A country that is involved in specialized production will have very efficient production because the more focus they have on one task, the more efficient they become at this task which reduces the time and money involved in producing a good.
- Gains from trade: Two countries that both have comparative advantages on different products will benefits greatly if they continue in their specialized products and trade. For example country X produces fabric at a very cheap rate and country Y produces rice at a very cheap rate. It will cost country X a greater amount to start rice production than to just trade and get rice from country Y and vice versa. So both countries benefit from specializing and trading.
- Growth Opportunities: A country can gain access to the world market which allows them to grow bigger and in turn increase their efficiency.
- Consumer Satisfaction: Specialization means that cost of production is lower which makes the cost of goods relatively cheaper.
Answer: C. Sympathetic nervous system
Explanation: The sympathetic nervous system is a part of the involuntary or autonomic nervous system, this is the system in the body that regulates the blood pressure, body temperature, pupil dilation, sweating and all the involuntary actions. It helps adjust the body fast enough to take action or react to stimuli without consciousness. When in the face of danger, let say for example, a snake coming towards you, a car coming towards you or hearing disturbing sounds in the dark. You next action or respond will be either to stand and fight or run away, The system responsible for that action (fight or flight) is the sympathetic nervous system.
Answer:
Correlation and causation are two very different things
Explanation:
Correlation means that two or more factors are dependent on each other in a way that one can be predicted with the help of the other. On the other hand, causation means that one thing causes another. For instance, a correlation between ice cream consumption and hot weather means that when its hot people eat ice cream more and in less hot weather people eat less ice cream. But if this correlation is confused with causation between ice cream demand and hot weather then it would mean that eating ice cream causes hot weather which will not be correct. Also for causation, three criteria should be met which are correlation, no effect of third extraneous variable and this casual effect should precede all other rational effects.
The answer is "Nature vs. Nurture".
The nature versus nurture debate is about the logical, social, and philosophical open deliberation about whether human culture, conduct, and identity are caused basically by nature or nurture. Nature is frequently characterized in this verbal confrontation as hereditary or hormone-based practices, while nurture is most generally characterized as condition and experience.
