acceleration = change in velocity/change in time
so...
a = 20 m/s / 2 seconds
a = 10
hope that helps :)
P.S. found this from Brainly User, sometimes all you have to do is search to find the answer.
Answer:
The average speed for the whole journey is 49.5 miles per hour.
Explanation:
Step 1 :
Here, both the ways, he covers the same distance. Then, the formula to find average speed is
= 2xy / (x+y)
Step 2 :
x ----> Rate at which he travels from New York to Washington
x = 45
y ----> Rate at which he travels from New York to Washington
y = 55
Step 3 :
So, the average speed is
= (2 ⋅ 45 ⋅ 55) / (45 + 55)
= 4950 / 100
= 49.5
<span>Lack
of training in getting the vital sign or worst, not knowing the right way to
take the vital sign could contribute to an inaccurate vital sign reading. For example,
if you are tasked to get the respiration of the patient, the rule is to count
inhale and exhale as one. But if you were not able to know this rule, and you
counted inhale as one and exhale as another, this could impair the vital
reading. </span>
Answer:
False: Quaternary structure is achieved when multiple polypeptide chains in protein come together.
Explanation:
There are four levels of protein structure: primary, secondary, tertiary, and Quaternary structure.
Tertiary structure is a protein structure, which is achieved when a protein folds into a compact, three-dimensional shape stabilized by interactions between side-chain R groups of amino acids.
However, Quaternary structure is achieved when multiple polypeptide chains in protein come together.
Answer:
Abiotic
Explanation:
The non living factors of the ecosystem which is essential for the survival of living factors of the ecosystem are abiotic factors.
Examples for abiotic factors include temperature, sunlight, water, wind etc....
