By adding tape to his BAAD, Cramwood increased its mass and increased
its inertia. The bigger BAAD requires more force to stop and ends up smacking Cramwood in the head when he applies the brakes.
What is inertia?Inertia is the tendency of an object to resist a change in its motion. Specifically, it is the property of matter that causes an object to maintain its state of rest or uniform motion in a straight line unless acted upon by an external force.
In other words, an object at rest will remain at rest, and an object in motion will continue to move at a constant speed and in a straight line, unless acted upon by an external force.
The amount of inertia an object has depends on its mass, with more massive objects having more inertia than less massive objects.

PLEASE IN 10 MINUTES!!
Answers
Answer:
Explanation:
Most antelopes are herbivores which means they eat only plants. If they cannot find enough plant matter to eat, slowly, the population in a herd of antelopes would go down from the lack of nutrients and energy they need from the food they eat(vegetation).
What is an ecosystem and what are its parts and functions?
What can challenge an ecosystem?
What are the roles of the water and food cycles in an ecosystem?
Answers
An ecosystem is a structural and functional unit of ecology where the living organisms interact with each other and the surrounding environment. In other words, an ecosystem is a chain of interactions between organisms and their environment.
Answer:
An ecosystem consists of all the organisms and the physical environment with which they interact. These biotic and abiotic components are linked together through nutrient cycles and energy flows. Energy enters the system through photosynthesis and is incorporated into plant tissue.
Parts & Functions Of an Ecosystem
The functions of the ecosystem are as follows: It regulates the essential ecological processes, supports life systems and renders stability. It is also responsible for the cycling of nutrients between biotic and abiotic components. It maintains a balance among the various trophic levels in the ecosystem.
What are the major parts of an ecosystem? An ecosystem includes soil, atmosphere, heat and light from the sun, water and living organisms.
Challenges For An Ecosystem
Some of the primary challenges include, but are not limited to, habitat loss, climate change including sea level rise, and levee stability.
The Role and Function of Water
Water cycle have several impacts on the nature - it takes part in weather, erosion and watering plants.
In short term it is positive, to see green grass and trees, not just bonedry dead nature.
In longer term we can see weather changing, clouds made of tiny drops of water coming and leaving - changing humidity (important for fungi and liches), local temperature changes etc.
Longest takes erosion and it is mostly about changing soils structure and nutritients for plants. Erosion can be also seen on riverbeds - in soft rocks/soils being wider, in harder rocks narrow. Also sedimentation in delta is important for development of border ecosystems.
Water makes organisms live and rocks move, that is the importance of water cycle.

1. is the first blank increases or decreases?
2. Is the second blank increases or decreases?
Answers
2. Increases
As a star's size increases, its luminosity increases as a star's temperature increases, its luminosity increases.
what is star luminosity ?luminosity is a calculated unit which means the energy produced by stars or galaxy , it is represent in the form of either joules per second or watts.
It generally depends on the size of the star that the lager sized star more energy it give, more luminous.
Secondly, the temperature of the star, if two same sized stars with different temperature, then higher temperature will be more luminous.
It is otherwise determined the actual measure of the absolute magnitude of the power output of the star.
It can be used to understand the stellar classification of various stars.
It can be used to predict the lifecycle of the star and helps astronomers.
luminosity is much more specific than brightness of the star as it is a mathematical calculation.
