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

Explanation:
In a particular breed of rabbits, fur color is gray or white. If a rabbit with gray fur and a rabbit with white fur reproduce and the offspring all have gray fur, what can you infer about the gene for fur color?
Answer:
D
Explanation:
The gene for dominant fur is dominant over white fur. The relationship between two genetic variants is referred to as dominant. Each gene has two alleles that an individual inherits from each parent.
What is dominant gene?One allele of a gene, known as the dominant gene, will be expressed if the alleles are different. The impact of the other allele, known as the recessive one, is concealed.
Dominant describes the relationship between two genetic variants. If one is in charge, the other must be subordinate. Then it is referred to as recessive.
A dominant gene, or dominant form of a gene, is a specific variant of a gene that expresses itself more powerfully on its own than any other version of the gene that the individual is carrying—in this example, the recessive—for a variety of reasons.
Therefore, The gene for dominant fur is dominant over white fur. The relationship between two genetic variants is referred to as dominant. Each gene has two alleles that an individual inherits from each parent.

What are the types of cell?The organisms which are made up of single cell has been known as the unicellular organisms and in the unicellular organism all the life processes takes place in a single cell. Amoeba has been known as an unicellular organism in which all the activities has to be related to the life carried out in a single cell.
Multicellular organisms are made up of the eukaryotic cell and the eukaryotic cell is consist of different cell organelles to carry out different functions in the cell. The multicellular organisms perform different life process in different cells because they have specific cell for specific function.
The unicellular organisms are made of one cell and carry out the processes of life as a single cell and the multicellular organisms are made up of two or more cells that have specific functions to contribute to the life processes.
Therefore, The substance will show net movement out of the cell more glucose and change to a black to purple color.

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.
