Answer:Explanation:
A microscopic hair examination can also determine if a hair was forcibly removed, artificially treated or diseased. A comparison microscope can be used to compare a questioned hair to a known hair sample in order to determine if the hairs are similar and if they could have come from a common source.
Answer:
in your mind yes but the bread is smaller than the earth thus it wouldnt turn the earth into a sandwich.
The period of Neptune is 165 years if the semi-major axis is 30.11 using the given formula.
Answer: Option D
<u>Explanation:
</u>
The period of any planet revolutions around the sun can be determined using Kepler third law. As that law states that square to the period of one complete revolution of every planet is equal to cube of semi major axis of that planet. So the formula can be derived as
Where T is the time taken for completing one revolution and a is the semi-major axis of the planet.
As here Neptune's semi major axis is given as 30.11. So the period of Neptune can be determined as follows:
Then take square root of this value:
T = 165 years
Thus, the Neptune takes 165 years for one complete revolution of the sun.
Answer:
Object D
Explanation:
Use Newton's Second Law to determine the acceleration that each object has.
The force applied in both cases is 50 N, but the mass for object C and object D is different.
Let's start with object C first:
- F = ma
- 50 N = 10 kg · a
- 50 = 10a
- 5 = a
The acceleration object C undergoes is 5 m/s².
Now let's calculate object D next:
- F = ma
- 50 N = 2 kg * a
- 50 = 2a
- 25 = a
The acceleration object D undergoes is 25 m/s².
Object D has greater acceleration because it has a smaller mass. The object with a smaller mass will accelerate more in order to satisfy Newton's 2nd Law.
