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.
Answer: can you translate this for me plz
Explanation:
Carbondioxide, being a green house gas has the property of trapping the heat from the sunlight and thus increasing the temperature of the place. As more and more rain forests are cut down and burned, there is an increase in this green house gas in the atmosphere thus leading to a steady increase in the temperatures.
As we look at the graphs that are given, we can see that the graph C shows the steady increase in the temperature as the time passes. Hence option C is the right answer
When light reaction occurs in the stroma of chloroplast glucose is produced
In this case, the dependent variable is the rate of respiration, the independent variable is the type of plant (either fruit or tomatoes), whereas a fixed variable may be the temperature.
<h3>What is a dependent variable?</h3>
A dependent variable is any type of experimental condition that is modified during the experiment.
Conversely, independent variables do not change along the experimental procedure (e.g., type of plant).
Finally, a fixed variable, also known as a control variable, is any condition that remains stable during the experimental procedure (in this case, for example, room ambient temperature).
In conclusion, the dependent variable is the rate of respiration.
