a. 3 meters^3 is the volume.
Explanation: This is when we find the volume of a rectangular prism which is whl so, 2*1.5*1=3^3.
b. 3000 is the mass.
Explanation: Density is calculated by mass/volume so, 1000=m/3. When we multiply 3 to both sides, we get 1000*3 which is 3000. So, 1000=3000/3.

Explanation:
V= I ⋅ R
where, V is the net potential difference in the circuit, I is the current in the circuit and R is the net resistance of the circuit.
In this case, V = 240 volts, I = 15 amperes.
240 = 15 ⋅ R
⇒ R = 240/ 15 = 16 ohms

What is the negative outcome of consolidation from many slaughterhouses across the US to only 13? A less greenhouse gas emissions B greater profits for agricultural corporations C less cost for farmers D greater possibility of contamination of our food
Answers
Answer:
D greater possibility of contamination of our food
Explanation:
Slaughterhouses are the places where animals are slaughter to supply food and when these places are consolidated, the few ones that remain receive a higher amount of animals and the meat from those animals can be combined in a batch which increases the chance of it to get contaminated. According to that, the answer is that the negative outcome of consolidation from many slaughterhouses across the US to only 13 is greater possibility of contamination of our food.
The other options are not right because they would be considered positive outcomes.
A camera lens focuses on an object 75.0 cm from the lensThe image forms 3.50 cm behind the lens. What is the magnification of the image?
Answers
Answer:
7/150
Explanation:
The following data were obtained from the question:
Object distance (u) = 75cm
Image distance (v) = 3.5cm
Magnification (M) =..?
Magnification is simply defined as:
Magnification (M) = Image distance (v)/ object distance (u)
M = v /u
With the above formula, we can obtain the magnification of the image as follow:
M = v/u
M = 3.5/75
M = 7/150
Therefore, the magnification of the image is 7/150.

The general kinematic equations of motion for vertical displacement can also be simplified significantly. Write the simplified
equation for y in this case. Explain how you have been able to simplify it from this general displacement equation:
Answers
Answer:
Δy = v₀t + (1/2)gt²
where g = 9.81 m/s if the body is moving downwards and g = -9.81 m/s if the body is moving upwards
Explanation:
The general kinematic equation for horizontal displacement is gives as:
Δx = v₀t + (1/2)at²
Where
Δx = change in the x direction
v₀ = initial velocity
t = time
a = acceleration
If the body is vertically instead of horizontally, Δx is changed to Δy
Δy = v₀t + (1/2)at²
For a vertical moving body, the acceleration it experiences is the gravitational accerelation of the earth 'g'
So the equation becomes:
Δy = v₀t + (1/2)gt²
where g = 9.81 m/s if the body is moving downwards and g = -9.81 m/s if the body is moving upwards
The general kinematic equations of motion for vertical displacement is written as [tex]h = v_0_yt - \frac{1}{2} gt^2[/tex].
The general kinematic equations of motion for vertical displacement is written as follows;
[tex]h = v_0_yt - \frac{1}{2} gt^2[/tex]
where;
h is the vertical displacement of the object[tex]v_0_y[/tex] is the initial vertical velocity of the objectg is the acceleration due to gravityt is the time of motion of the objectThus, the general kinematic equations of motion for vertical displacement is written as [tex]h = v_0_yt - \frac{1}{2} gt^2[/tex].

In which of the following situations or places would you want to reduce the
force of friction?
I A. Skiing down a hill during a race.
B. Walking down a steep hill.
C. Sitting in the bed of a pickup truck while it turns a corner
D. In the axle of the wheels while you ride your bicycle.
Answers
Answer:
D
Explanation:
The correct answer would be in the axle of the wheels while you ride your bicycle.
Options A, B, and C requires that the forces of friction is increased in order to have more control.
However, option D requires that there is a minimal frictional force in the axle of the wheels of a bicycle while riding so that a little effort would be required to keep the bicycle moving.
The lesser the friction, the lower the effort that would be needed to keep the bicycle moving and vice versa.

What is Newton's second law?
Newton's Second Law states that The resultant force acting on an object is proportional to the rate of change of momentum.
The mathematical expression for Newton's second law is as follows
F = m*a
where F represents the force applied
m is the mass of the object
a is the acceleration of the object
The initial acceleration of an airplane with a total mass of 850 kg has an engine malfunction, causing it to provide a constant horizontal force of 4000 N.
F =m*a
4000 N = 850×a
a= 4.7 m/s²
An acceleration of airplane when the pilot, who has a mass of 80 kg, decides to eject from the airplane. With the reduced total mass,
the horizontal force is the same 4000 N, now the total reduced mass the airplane is 770 kg
F =m*a
4000 =770×a
a = 5.2 m/s²

C. 48 m
D. 24 m
Answers
Answer:
D. 24 m
Explanation:
Running up - velocity + 30 m/min
Escalator 's moving down velocity - 24 m/min
Sum velocity (30 - 24) = 6 m/min
6 m/min * 4 min = 24 m
The graph below shows the conservation of energy for a skydiver jumping out
of a plane and landing safely on the ground. Which energy is represented by
line B?
A. Elastic energy
B. Kinetic energy
C. Light energy
D. Potential energy
Answers
Answer:
The correct option is:
B) Kinetic Energy
Explanation:
We know that if a body is placed at a certain height, it possesses Potential Energy, which is represented by 'mgh'. In this case, when the skydiver is present in the plane, before jumping, he has potential energy as he is at height 'h'.
As Kinetic energy is given as '(1/2)mv²' dependent on velocity of the object, when the skydiver jumps of the plane, his height starts decreasing, which decreases his Potential Energy. As energy can neither be created or destroyed, but is converted to one form or another, all this Potential energy starts to convert into Kinetic energy. As Potential Energy decreases with distance, Kinetic energy increases. Hence, line B represents Kinetic Energy.
Why does the pattern of colors repeat in a thin soap film? Please use 2 content related sentences. (ref: p.522-530)
Answers
Answer: The pattern of colors that repeat in a thin soap film is a result of the interference of light waves reflecting off the front and back surfaces of the film. The specific colors seen are determined by the thickness of the film, with different wavelengths of light being reflected or refracted at different angles, creating the characteristic rainbow pattern.

a toy airplane is flying at a speed of 8 m/s with an acceleration of 0.9 m/s^2. How fast is it flying after 2 seconds? A)9.8 m/s B)8.1 m/s C)5.2 m/s D)3.6 m/s
Answers
Answer:
A) 9.8m/s this answer is correct.
The acceleration is increasing by 0.9m/s^2 .
so, in each second it will increase by 0.9m/s^2.
Therefore, in 2 second
0.9 * 2
= 1.8m/s
Now,
8 + 1.8
= 9.8m/s
What would happen to a satellite if its orbit speed doubled?
Answers
Answer:
The radius of orbit will decrease by 1/4, the satellite will come closer to Earth
Explanation:
The orbital speed of any body revolving in an orbit around another boyd is given by:
v (orbital) = √(G · M(central body)/R)
Where G is the gravitation constant.
If the body, e.g satellite is moving around the Earth, then the mass of central body M will also be a constant. Therefore, the only thing on which the orbital velocity will depend on will be Radius of the orbit R.
v ∝ 1/√R
√R ∝ 1/v
Take square:
R ∝ 1/v²
If the velocity of satellite will doubles, then:
R' ∝ 1/ (2v)²
R' ∝ 1/4v²
R' ∝ (1/4)(1/v²)
R' ∝ (1/4)(R)
The radius of orbit will decrease by 1/4, the satellite will come closer to Earth

The correct answer is B) Giving Congress the power to create courts
Explanation:
One of the principles the Constitution mentions in the preamble is Justice, this is mentioned in "We the people of the United States, in order to form a more perfect union, establish justice..." According to this, a priority is to make the country have justice, which is possible through courts, laws, among others. In this context, the action that would be allowed is "Giving Congress the power to create courts" because this might ensure the justice principle is applied in the U.S.
