Magnetic force - B.
Electrical force - A.
Gravitational force - D.
Contact force - C.
<h3><u>Explanation:</u></h3>
When a charge moves about its path, it produces a magnetic force around it. This magnetic field is perpendicular to the axis of movement of the charge and is directly proportional to the amount of charge, speed of the charge, and inversely proportional to distance between the charge and the point of measurement. Michael Faraday discovered this phenomenon.
Electrical force of attraction or repulsion is seen between the two charged bodies, or one charged body and one uncharged body which can induce charge to the uncharged body. The attraction or repulsion between the charged bodies are seen if the bodies are close enough, and this is called electrical force.
The gravitational force is also a non contact force that is seen between two bodies which is always attractive in nature and is seen between any two bodies.
A contact force like friction is a type of force that takes place only when two bodies are in contact with each other.
C. Because mutations are varieties
Answer:
Dependent Variable: Babies that use the formula
Independent Variable: Babies Without the formula
Explanation:
As the formula dose Increases, So does the weight of the babies (figurativly)
This is the Dependent variable because it depends on another factor
The Independent variable doesn't depend on the amount of formula taken because it doesn't use the formula, therefore it doesn't depend on anything, its Independent.
Answer - A. Deep because there is less O2 exchange
Reasoning - Bacteria has been known to only use half a percentage which is .5 percent of O2.
Hi I am a farmer and if you planet something in a spot year after year and don`t move it around you will drain the nutrients from the soil and it will not be good for farming any more so I will go with answer B. I hope that is right.
