What type of contraction involves the development of tension but no change in length?.

1 answer:

6 0

An isometric contraction is the kind of contraction that leads to development of tension but no increase in length.

An isometric contraction occurs as the muscle produces tension without changing the angle of a skeletal joint. Isometric contraction is a static muscle action that helps to maintain the posture. For example, the antigravity muscles. It occurs in the biceps when the arms may be holding a weight. In such a posture, the biceps enlarge due to holding of weight and produces tension but do no increase in length. It stops the flexion of elbow. In such contraction, no work is done, and lesser amount of heat energy is released in comparison to isotonic contractions.

...Study of secondary sources. This is one of the differences between the two educational styles. Renaissance humanism heavily focused on revisiting the Classical period of Ancient Rome and Greece. Humanists favored studying primary sources over secondary sources, which they saw as being corrupted by modern scholars and thus inaccurate and misleading. Scholastics of the medieval ages were however very fond of secondary sources.

Law Incorporation [45]

The correct answer (c) the fundamental attribution error.

The fundamental attribution error refers to an individual's tendency to attribute another's actions to their character or personality, rather than external situational factors beyond their control.

To understand people's behavior, we use attribution theory to attribute feelings and intentions to them. For example, when we see someone shouting on public transportation, we may unconsciously apply this theory. You could blame their personality, assuming they are an angry person.

Fundamental accountability Error results from our differing perceptions of our own and others' behavior. When we perceive others' behavior, we essentially see them moving while their surroundings remain constant. As a result, they and their actions become the focus of our attention.

Assume that your firm wants to choose between two project options:

stepladder [879]

Answer: Project B should be chosen as it has a higher NPV of $70,314.97

Explanation:

You need to find the Net Present Value of both projects. The better investment is the one with a higher Net Present Value.

As there will be inflation, this needs to be included in the required return:

= 10% + 3%

= 13%

This will be the rate for discounting.

Project A:

Net Present Value = Present value of cash inflows - Cash invested

Present value of cash inflows:

This is a constant inflow so is an annuity. Present value will be:

= Amount * Present value interest factor of annuity, 5 years, 13%

= 150,000 * 3.5172

= $527,580

Net Present value = 527,580 - 500,000

= $27,580

Project B:

Net Present Value = Present value of cash inflows - Cash invested

= 50,000 / (1 + 13%)² + 200,000 / 1.13³ + 300,000 / 1.13⁴ + 200,000 / 1.13⁵ - 400,000

= 470,314.97 - 400,000

= $70,314.97

Project B should be chosen as it has higher NPV.
