Lauren wants to know which location in her apartment is best for growing African violets. She has three African violets. She puts one on the balcony, one by the kitchen windows, and one on the mantel in the living room. Each plant has the same pot and the same soil, and Lauren gives each plant the same amount of water. Which is the independent variable?
Answer:
First, before determining which variable is which, we go over the definition of each. The independent variable is the one which is intentionally changed in order to investigate its effect on the dependent variable. The dependent variable is monitored and changes occur in it due to the changing conditions of the independent variable. In this case, the location of the African violets is the independent variable as it is intentionally changed, while the rate of growth of the African violets is the dependent variable as it is being measured.

D. Rocks include quartz and diamond, minerals include granite and marble.
The correction that is needed to be made is that rocks do have specific chemical compositions and minerals do as well. The correct option is C.
What are minerals?Minerals are elements found on the Earth and also in foods which our bodies require for normal development and function.
Minerals generally have certain specific chemical compositions, but it is not in case of rocks.
Thus, the correct option is C.

How are seatbelts related to inertia? Write you answer in complete sentences.
I need answer asap!!!
Answer:
Seat belts are in cars to the effects of inertia. ... When the car hits the wall, you would keep moving in a straight line and at a constant speed until the dashboard applies a force. Seat belts hold you and passengers down, protecting them from their own inertia.
Explanation:
their is the answer so okay
Answer:
Inertia is the tendency of an object to resist a change in velocity.
When a car stops suddenly, your body is still going at the same speed the car was before it stopped (say 65 MPH). Without the belt strapping you in from behind, you would fly forward at nearly that same speed (65).
But thanks to the seatbelt, it stops your body's inertia.
If a truck that is traveling at 15 mph speeds up to 45 mph in 10 seconds, what is the truck’s acceleration?
PLZ HELP!!!! I NEED A ANSWER AND THE FIRST ONE TO ANSWER WILL GET A BRAINLIEST!!!!
Answer:
3miles per hour^2
Step-by-step explanation:
given data
initial speed u= 15mph
final speed v=45mph
time taken t= 10 seconds
Step two:
Required
acceleration a=?
applying the first equation of motion
v=u+at
substitute we have
45=15+a*10
45=15+10a
make a subject of the formula
45-15=10a
30=10a
divide both sides by 10
a=30/10
a=3miles per hour^2
Answer:
3m/s
Explanation:
15mph is the intial and 45 is the final subtract them and divide by ten

How does the Coriolis effect impact the Gulf Stream and the Brazil Current?
It turns the Gulf Stream southwest and the Brazil Current northeast.
It turns the Gulf Stream northwest and the Brazil Current northeast.
It turns the Gulf Stream northeast and the Brazil Current southwest.
It turns the Gulf Stream northeast and the Brazil Current northwest.
Answer:
The Coriolis effect acting on these currents causes northern hemisphere gyres to move in a clockwise direction and southern hemisphere gyres to move in a counterclockwise direction.
Explanation:
The Coriolis effect does the impact on the Gulf stream and the Brazil Current by turning the Gulf Stream towards northwest and Brazil Current northeast. Thus, the correct option is B.
What is Coriolis effect?The Coriolis effect results in bending the direction of surface currents to the right in the Northern Hemisphere and left in the Southern Hemisphere. The Coriolis effect causes winds and currents to form the circular patterns. The direction in which they spin depends upon the hemisphere in which they are present.
Coriolis Effect is named after the French mathematician and physicist Gaspard-Gustave de Coriolis. It affects the weather patterns of an area, it affects the ocean currents, and it also affects air quality.
Therefore, the correct option is B.

A student is trying to make a structure to conduct heat quickly during cold winter days.
Which material should the student use?
A. wood
B. plastic
C. glass
D. metal
A student who is trying to make a structure to conduct heat quickly during cold winter days. The student should use metal for heat conduction. Thus, the correct option is D.
What are metals?
A metal is a material which is when prepared freshly, polished, or fractured, shows the lustrous appearance, and also conducts electricity and heat relatively well through them. Metals are typically ductile in nature i.e., can be deformed into a thin wire and malleable. All of these properties are the result of the metallic bond which is present between the atoms or molecules of the metal.
Metals are the cationic elements. These are positively charged due to the loss of electrons from the valence shells. There are about 70 metals out of 92 natural elements present in the periodic table.
Therefore, the correct option is D.

How are seatbelts related to inertia? Write you answer in complete sentences.
I need answer asap!!!
Answer:
Inertia- the tendency of an object to resist a change in velocity
Explanation:
Say a car was going at 65 MPH, but suddenly stopped. For all of the people in that car, their bodies would keep moving forward at 65 MPH until stopped by an equal force (say, the thing right in front of each person) The seatbelt is there to protect you from your own inertia.
Answer:
inertia is the constant state of movement so seatbelts stop that when you stop the car.
Why do regions/places have different types of climates? Try to give an example in your answer
Answer:
The climate of a region depends on many factors including the amount of sunlight it receives, its height above sea level, the shape of the land, and how close it is to oceans. Since the equator receives more sunlight than the poles, climate varies depending on its distance from the equator.
