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.
Match each type of fossil to the description that best matches.
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
What makes greenhouse gases different from other atmospheric gases?
Greenhouse gases reduce the amount of natural resources on Earth.
Greenhouse gases allow thermal energy to pass through the atmosphere and back out into space.
Greenhouse gases account for the direction in which water and air move.
Greenhouse gases trap thermal energy and reflect the sun’s harmful radiation back to Earth.
Greenhouse gases are different from other atmospheric gases for the following reason:
Greenhouse gases trap thermal energy and reflect the sun’s harmful radiation back to Earth.Thus, the correct option is D.
What are greenhouse gases?Greenhouse gases may be defined as those gases that absorb infrared radiations which are competent to trap heat. Some examples of greenhouse gases are carbon dioxide, methane, CFCs, nitrous oxide, etc.
Greenhouse gases are more complex as compared to other gas molecules in the atmosphere. It has a structure that makes such gases more competent to absorb heat and radiate back to the Earth's surface. These gases trap the ultraviolet radiation from the sun and emit toward the earth's surface. Such gases are responsible for greenhouse effect.
Greenhouse gases are harmful to the environment as well as the health of living entities that constantly living in various ecosystems of the environment.
Therefore, the correct option for this question is D.

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.
