Question

which of the following objects is in equilibrium : an object that moves at constant acceleration,an object that moves at constant velocity

Solution 1

Answer:

An object that moves at constant velocity

Explanation:

For an object to be in equilibrium, according to Newton's first law, the object must maintain its state of rest or movement without a resulting force acting on the object.

In this case the object in both options is in motion, but the only one in which that movement is constant and without resulting forces is when it moves at constant speed, so it is in equilibrium.

On the other hand, when it moves with at constant acceleration, by Newton's second law $F = ma$ ( $m$ is the mass and $a$ is acceleration), if there is an acceleration there will be a resultant force so the object is not in equilibrium.

The answer is an object that moves at constant velocity is in equilibrium.

Solution 2

Constant velocity is the answer

Question

What makes air pollution a global problem? A Wind B Travel C Gravity D Sunlight

Solution 1

Wind is what makes air pollution a global problem. Details about air pollution can be found below.

What is air pollution?

Air pollution refers to the release of toxic substances called pollutants into the atmosphere.

Air pollution is a global problem because it is transported via the wind to different regions of the planet.

This is why air pollution that arises from a region can affect other regions of the planet.

Therefore, wind is what makes air pollution a global problem.

Question

Which organism in the food web above is sometimes a first-level consumer and sometimes a second-level consumer?Explain

Solution 1

The answer is Mouse/Herbivore a first-level consumer and sometimes a second-level consumer

what is organism?

An individual form of life, such as a plant, animal, bacterium, protist, or fungus; a body made up of organs, organelles, or other parts that work together to carry on the various processes of life.

First organism is always a producer (plant) such as grass.The 2nd organism is the first level or primary consumer. Ex. Mouse - It eats the producer, so it is a herbivore.

Question

How does applying force to an object affect its motion

Solution 1

The force you apply to an object and its motion are directly proportional. The more net force is used against an object, the more it will (or be likely) to move. (this does not factor in friction or resistance which honestly, is just another variable)
