Four students created an experiment to determine the most efficient type of wheel and axle combination to use on a model racing car. The cars raced down a smooth, wooden incline track. Based on their results, what would be the best NEW combination Paulo should try on his next car if he wanted it to be more efficient?

The ideal new combination Paulo should attempt on his next car cannot be determined without understanding the precise outcomes of the experiment.

Depending on the particular parameters tested, the students' experiment may have examined different combinations of tire and axle sizes, materials, or shapes, and the results may have suggested varying levels of efficiency.

Paulo must therefore examine the experiment's findings and data before deciding which combo or combinations delivered the best results. Before choosing a new combination to try on his next vehicle, he should think about elements like cost, the accessibility of materials, and ease of assembly.

Paulo should examine the outcomes of the experiment carried out by the four students before deciding on the best new combination for his racing vehicle.

This would enable him to determine which wheel and axle combination(s) performed best in the situation. Paulo can select a different combination to test out on his next racing vehicle based on the outcomes. When choosing a novel combination, costs, material accessibility, and ease of assembly should all be taken into consideration.

With continual improvements made to microscopes over time, magnification technology advanced enough to discover cells in the 17th century. This discovery is largely attributed to Robert Hooke and began the scientific study of cells. Over a century later, many debates about cells began amongst scientists. Most of these debates involved the nature of cellular regeneration and the idea of cells as a fundamental unit of life. The cell theory was eventually formulated in 1839.

The three tenets to the cell theory are:
1. All living organisms are composed of one or more cells.
2. The cell is the basic unit of structure and organization in organisms.
3. Cells arise from pre-existing cells.
Which TWO of these contributed to formation of the cell theory?

Which statement about radiation is FALSE? The polar regions do not receive as much solar radiation as the equator. Radiation can travel through the vacuum of space. Some radiation from the sun reflects off the clouds and back into space. All parts of earth's surface receive the same amount of radiation from the sun.​
