PLZ HELP!!!! I NEED A ANSWER AND THE FIRST ONE TO ANSWER WILL GET A BRAINLIEST!!!!

Answers

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.

Answers

Greenhouse gases allow thermal energy to pass through the atmosphere and back out into space

Explanation:
Greenhouse gases are transparent to incoming (short-wave) radiation from the sun but block infrared (long-wave) radiation from leaving the Earth’s atmosphere

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.

How are seatbelts related to inertia? Write you answer in complete sentences.
I need answer asap!!!

Answers

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.

The cell cycle is the replication of reproduction of cells, whether in eukaryotes or prokaryotes. It is important to organisms in many different ways, but overall it allows them to survive. For prokaryotes, the cell cycle, called binary fission, allows for them to live on by dividing into two new daughter cells.

Are you talking about cell division and mitosis and that kind of stuff? If so , first is interphase which is growth and development second is prophase where you can see the chromosomes and spindle fibers everywhere, third is metaphase where the chromosomes line up and the spindle fibers are attached to the chromosomes, fourth is anaphase where the chromatid pairs separate, and last is telophase where the cell begins to form a new nucleus and split and goes back to interphase and the cycle continues. If this stopped then you would die. I hope this helped
