Answer:
The options are not provided, so i will answer in a general way.
We know that:
The movement is along a straight horizontal surface, then we have one-dimensional motion.
The speed is 2m/s
We want a graph of position vs time.
Now, remember the relation:
Distance = Speed*Time
Then we can write the position as a function of time as:
P(t) = 2m/s*t + P0
Where t is our variable, that represents time in seconds, and P0 is the position at time t = 0seconds, we can assume that this is zero.
Then the equation is:
P(t) = 2m/s*t
And the graph is something like:
Answer:
a. Electric field lines can never cross each other.
d. Wider spacing between electric field lines indicates a lower magnitude of electric field.
Explanation:
a. The electric field lines cannot be crossed, since this would mean that there would be more than one electric field vector for the same point at the place where the crossing occurs.
d. The space between the field lines is inversely proportional to the intensity of the electric field.
Yeah what do you want me to answer for this question?
I have worked in both situations, and I understand each
of their preferences.
I hope both Kevin and Marsha are successful at their jobs,
and may they live long and prosper.
Thank you for sharing their heartwarming stories.
Answer:
Person in the Control group: SpongeBob
Independent variable: Muscle cream
Dependent variable: Amount of muscle power
Larry's conclusion should conclude that the MUSCLE CREAM double a person’s muscle power when used as part of a muscle-building workout.
Explanation:
Independent variable is the variable that is changed or manipulated by the experimenter in an experiment. In this experiment, the MUSCLE CREAM is the variable being changed for the groups i.e. Patrick and SpongeBob. Hence, the MUSCLE CREAM is the independent variable.
The dependent variable is the variable that responds to changes made to the independent variable. In this experiment, the dependent/responding variable is the AMOUNT OF MUSCLE POWER.
Control group is the group of an experiment that does not receive the experimental variable (muscle cream). In this experiment, the person that does not receive the experimental variable is SpongeBob i.e. was lathered with the regular lotion.
Larry, who is the one conducting the experiment, should conclude that MUSCLE POWER doubles a person’s muscle power when used as part of a muscle-building workout.
