a. what is the independent variable
b. what is the dependent variable
c. explain what type of graph should be used to display this data and why
d. what would the label of the X axis be?
Answers
Answer:
A) Year
B) Number of Wolves
C) Bar graph
D) Year
Explanation:
A) The year is always definite; it never depends on any other variable. The number of wolves doesn't change the year.
B) The number of wolves depends on variables like food, water, shelter, ect. The number of wolves isn't magical and just change on its own.
C) I think a bar graph will work best best it shows a more visual representation of the number of wolves. A line graph can be confusing with how proportional and scattered the data is, and a scatterplot diagram would be better if you were tracking the number of wolves and another variable, like available food or something like that. With the given data, to me, a bar graph makes the most sense.
D) The independent variable tends to always be what x stands for, and the dependent variable always tends to be what the y stands for. Since the year is our independent variable, and our x is the year, we can name the x axis "Year." Its simple, but it works.
I hope this helps!

Why is visible light between infrared and ultraviolet
Answers
Answer:
The infrared has longer wavelengths (700 nm to 1 mm) than those of visible lights (390 nm to 700 nm). Note though that visible light is the only radiation that can be seen by the human eye. The ultraviolet is much more intense and has a shorter wavelength (400 nm to 10 nm) compared to visible light.
Explanation:
GREETINGS!
Visible light is in between UV and IR region because visible light has a wavelength ranging from 400nm to 700nm, and below 400nm is the region of UV and above 700 is the region of IR, So visible lights is in between UV and IR
To understand things more clearly you could see the electromagnetic spectrum to see which ray lies lies in what region.

If a student leaves home at 7:30 AM to walk to his school 2 km away, stops at a neighbor's house for 15 min, then arrives at school at 8:00 AM, what is the student's average speed for the trip to school?
Answers
Answer:
The student's average speed for the trip to school is 4 [tex]\frac{km}{h}[/tex]
Explanation:
Speed is a quantity that relates the displacement that an object makes in a given unit of time. In other words, speed is a physical quantity that expresses the relationship between the space traveled by an object, the time used for it and its direction.
Since the average speed relates the change in position to the time taken to effect said change, then:
[tex]speed=\frac{change in position}{time}[/tex]
In this case, the student travels a total distance of 2 km between his home and school and the total time spent on the trip is 30 minutes, then:
change in position= 2 kmtime= 30 minutes= 0.5 hours (being 60 minutes = 60 hours)Replacing:
[tex]speed=\frac{2 km}{0.5 hours}[/tex]
Solving:
speed= 4[tex]\frac{km}{hours}[/tex]
The student's average speed for the trip to school is 4 [tex]\frac{km}{h}[/tex]

A motorcyclist started a race from START line and from rest, and accelerated with the acceleration of 2 m/s2 for 7 seconds. Then he increased the acceleration to 4 m/s2 and went with that acceleration for 8 seconds. What was the racer’s position from the START line after 7+8 seconds from the start of the race?
Answers
Answer:
289 m .
Explanation:
s = ut + 1/2 at² , u is initial velocity , t is time , a is acceleration and s is distance covered .
For t = 7 s
s = 0 + 1/2 x 2 x 7²
= 49 m
velocity after 7 s
= a x t = 2 x 7 = 14 m /s
for next 8 s , initial velocity u = 14 m /s
S = ut + 1/2 at²
= 14 x 8 + 1/2 x 4 x 8²
= 112 + 128
= 240 m
Total displacement in 7 + 8 s
= 49 + 240 = 289 m .

A runner is jogging in a straight line at a steady vr= 8.8 km/hr. When the runner is L= 3 km from the finish line, a bird begins flying straight from the runner to the finish line at vb= 17.6 km/hr (2 times as fast as the runner). When the bird reaches the finish
Answers
Answer:
Explanation:
Speed of runner Vr = 8.8 km / h
distance to be covered = 3 km
time taken by runner to reach finish line = 3 / 8.8 h = .34 s
distance covered by the bird during this period = speed of bird x time
= 17.6 x .34 = 5.98 km .

An automobile tire with a radius of 0.30 m starts at rest and accelerates at a constant angular acceleration of 2.0 rad/s2 for 5.0 s. What is the angular displacement of the tire?
Answers
Answer:
The value is [tex]\theta = 25 \ radian[/tex]
Explanation:
From the question we are told that
The radius is [tex]r = 0.30 \ m[/tex]
The acceleration is [tex]\alpha = 2.0 \ rad/s^2[/tex]
The time taken is [tex]t = 5.0[/tex]
Generally the angular displacement is mathematically represented as
[tex]\theta = \frac{s}{r}[/tex]
Here s is the linear distance covered by the tire which is mathematically represented as
[tex]s = u t + \frac{1}{2}a t^2[/tex]
Here u is 0 given that the car started from rest and
[tex]a = \alpha * r = 2.0 * 0.30= 0.6\ m/s^2[/tex]
So
[tex]s = 0 + \frac{1}{2}*0.6* 5^2[/tex]
[tex]s = 7.5 \ m[/tex]
So
[tex]\theta = \frac{7.5}{0.30}[/tex]
=> [tex]\theta = 25 \ radian[/tex]
The distance between pitcher and catcher on a baseball field is 18.4 m. If a pitcher releases a ball from a height of 1.5 m and the catcher catches the ball right at ground level, how fast did the pitcher throw the ball?
Answers
Answer:
33.26 m/s
Explanation:
The initial velocity of the ball can be determined by;
R = v[tex]\sqrt{\frac{2H}{g} }[/tex]
Where R is the range (distance between pitcher and catcher), H is the height covered, v is the initial velocity and g is the acceleration due gravity (9.8 m/[tex]s^{2}[/tex]).
So that;
18.4 = v[tex]\sqrt{\frac{2*1.5}{9.8} }[/tex]
= v [tex]\sqrt{\frac{3}{9.8} }[/tex]
= v [tex]\sqrt{0.3061}[/tex]
= 0.5533v
⇒ v = [tex]\frac{18.4}{0.5533}[/tex]
= 33.2550
The initial velocity of the ball is 33.26 m/s.This is the velocity with which the pitcher threw the ball.
3. Elizabeth tested how high five different brands of new tennis balls would bounce when dropped from the same height of 2 meters. She dropped the balls so that they hit the same floor tile each time. In this consumer testing she did not have a control experiment but took factual information from the manufacturers on how well their product bounced (resiliency). She tested 100 balls of each brand. She measured the bounces in centimeters. what is the controlled variable and the Independant variable and the dependent variable
Answers
Answer:
Controlled variable: the height from which the ball is dropped and the floor tile on which the ball hits
Independent variable: different tennis ball brands
Dependent variable: height of bounce in centimeters
Explanation:
Scientific experiments have three major kinds of variables:
Independent variable: This is the variable that is subject to the manipulation of the experimenter. The values of this variable are determined by the experimenter. In this example, Elizabeth determines the brand of tennis ball to be tested, hence the tennis ball brand is the independent variable
Dependent variable: This variable has values which are a result of the effect of the manipulation of the independent variable. The values of the dependent variable are not under the direct control of the experimenter. They are simply the results of the experiment. Here, the height to which the ball bounces is not predetermined, hence it is the outcome or dependent variable.
Control variables; These are variables that can affect the outcome of the results of the experiment but are kept constant throughout the experiment, to rule out biases when testing the effect of the independent variable.

Explanation:
This problem can be solved using the definition of velocity which is the relationship between space and time.
v = x/t
where:
v = speed [m/s]
x = distance = 105 [m]
t = time = 70 [s]
v = 105/70
v = 1.5 [m/s]
Answer:time.
v = x/t
where:
v = speed [m/s]
x = distance = 105 [m]
t = time = 70 [s]
v = 105/70
v = 1.5 [m/s]
Explanation:time.
v = x/t
