1. A student weighing 460.0 N climbs a vertical stairway that is 4.5 m high in 32.5 seconds. What is his power output?
2. A worker pushes horizontally on a large crate with a force of 215.0 N and the crate moved 2.6 m. How much work was done?
3. While rearranging a dorm room, a student does 318.0 J of work in moving a desk 2.4 m. What was the magnitude of the applied horizon

Answers

Answer 1

Answer:

1. Power = 63.69 Watts.

2. Workdone = 559 Joules.

3. Force = 132.5 Newton.

Explanation:

Given the following data;

1. Force = 460N

Distance = 4.5m

Time = 32.5 seconds.

To find the power;

First of all, we would determine the work done by the student using the formula;

Workdone = force * distance

Workdone = 460 * 4.5

Workdone = 2070 Joules.

Now, we can calculate the power;

Power = workdone/time

Power = 2070/32.5

Power = 63.69 Watts.

2. Force = 215N

Distance = 2.6 m

To find the work done by the worker;

Workdone = 215 * 2.6

Workdone = 559 Joules.

3. Workdone = 318 Joules

Distance = 2.4m

To find the magnitude of force applied;

Force = workdone/distance

Force = 318/2.4

Force = 132.5 Newton.

Answers

Answer:

Green buildings can be built from the ground up or reconstructed from existing buildings using revamped, recycled, reused, and renewable resources. They create healthy indoor environments for human use and healthy outdoor environments for nature’s use. They usually encompass landscaping with native plants, which reduce the amount of water used. Two examples of green buildings are Fusionopolis in Singapore and Hearst Tower in New York City.

What is global periphery?

According to the theory of world systems, peripheral nations are those that have less developed economies than semi-peripheral and core nations.

Typically, these nations receive a disproportionately small percentage of the world's wealth. The economic scale between core and periphery nations is reversed.

They are the least developed nations in comparison to the core and semi-periphery nations, and are typically low- or middle-income nations that receive an unfairly little fraction of the world's wealth.

Megacities exhibit unplanned expansion patterns and frequently have squatter settlements, which is the attribute that best describes a geographic trait shared by megacities in the global periphery.

Thus, the correct option is C.
