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 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.

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.
Answer,because of the bench marks
Explanation:
regions have different type of climates because of various reasons it could be determined by the fove benchmarks equator ,arctic circle,antartic circle,tropic of cancer and capricorn.
Alison finds the total mass of a sample of baking soda, a balloon, and a glass container with vinegar in it. She adds the baking soda to the vinegar and immediately places the balloon over the mouth of the container. After the reaction is complete, she again finds the total mass of the system.
Which statement is true:
1. The mass does not change because chemical changes observe the law of conservation of mass.
2. Mass is gained during the reaction because a chemical change is taking place.
3. Mass is lost during the reaction because the gas is less dense than the baking soda or vinegar.
4. Mass is lost during the reaction because the gas can change in volume but baking soda and vinegar cannot.
Answer:
2. Mass is gained during the reaction because a chemical change is taking place

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.
