Instructions: Select the Intro Simulation located at the bottom of the simulation window.
Once the Intro Simulation loads, select all of the following from the options located on the right-hand side of your screen:
U-shaped ramp
Pie Chart
Bar Graph
Grid
Speed
Leave the mass on the center setting
3. Then, drag your skater onto the highest part of the U-shaped ramp and select the start arrow to begin. You may use the pause button to stop your skater and the slow motion button to slow the skater down.
Record your data in the chart below using the following terms: increases, decreases, or stays the same. Be sure to complete the entire data chart.

Position of the Skater on the U-shaped Ramp
Amount of Potential Energy
Amount of Kinetic Energy
Speed
Total Energy
1
Moving down the ramp from 6 meters to 4 meters

2
Moving down the ramp from 4 meters to 2 meters

3
Moving up the ramp from 2 meters to 4 meters

4
Moving up the ramp from 4 meters to 6 meters

marginal cost is a microeconomic measure that us to evaluate the extent to which the level of production of a good is sustainable in accounting, that is, to how many quantities the company plans to profit from the production of the good.

the concept of marginal cost is simple, it means the cost of producing one more item. for example, in the case of pies, the marginal cost is the cost of producing one more pie than those that have already been produced.

it is important to understand that productive activity influences marginal cost. the marginal cost of some goods can be very high, while others may be insignificant. for example, the marginal cost of producing an extra plane is very high. already the marginal cost of a water company to provide 1l more water is derisory.

in the case of pies, the cost involves the inputs, the labor and the fixed cost, which involves the fixed space of the bakery. the level of production initially has the marginal cost decreasing because there is space and manpower available. however, to produce more you have to hire more workers and buy more inputs. if physical space is limited, workers will conflict with places, inputs and their productivity will decrease, meaning there is an optimum point of production for each level of space and manpower. from this point on, the productivity of the workers will be getting smaller because of lack of space, so that the marginal cost of producing one more pie will be increasing. so, although you have not posted the chart, but if you have the answer, you can see that my explanation goes according to the marginal cost curve that will increase from the 4th pie, answer (c).

could you show the options for the answers? : )
