Use a computer-interfaced Force Sensor to measure force. Calculate actual mechanical adavantage and ideal mechanical advantage. Determine efficiency. Make conclusions about pulley systems.
Answer:
2. The velocity of the particle is tangent to the circle
Explanation:
1. The velocity of the particle is constant.
Incorrect
Reason : Since the tangential speed is not constant, hence the velocity of the particle is not constant.
2. The velocity of the particle is tangent to the circle.
Correct
Reason : In circular motion, the direction of velocity is always given by the tangent to the circle.
3. The acceleration of the particle is constant.
Incorrect
Reason : The tangential speed of the particle is not constant which in turn keeps changing the centripetal acceleration of the particle. hence the acceleration of the particle is not constant.
4. The acceleration of the particle is toward the center of circle.
Incorrect.
The ratio method exists as an estimating technique which requires knowledge and experience,
<h3>What is meant by
ratio method?</h3>
- Ratio technique: This method uses a basic project attribute, like size in square meters or the number of software features, and the cost per meter or feature to project the overall cost and length of the project.
- Ratio analysis in project management can measure how effectively resources are being managed and how efficiently the project is running. The balance sheet and income statement of an organization are typically where financial ratios in the corporate environment are derived.
- A measure of the relationship between a proposed project's relative costs and benefits, expressed in monetary or qualitative terms, is the benefit-cost ratio (BCR). The expectation is that a project with a BCR of greater than 1.0 will provide a firm and its investors with a positive net present value.
Hence, The ratio method exists as an estimating technique which requires knowledge and experience,
