Celia is staring at the clock waiting for school to end so that she can go to track practice. She notices that the 4-inch-long minute hand is rotating around the clock and marking off time like degrees on a unit circle.Part 1: How many radians does the minute hand move from 1:25 to 1:50? (Hint: Find the number of degrees per minute first.)

Answers

Answer 1

Answer:

Answer:

The minute hand moves $(5\pi)/(6)$ radians.

Step by step explanation:

We know that measure of complete circle is 360 degrees.

In a clock a complete circle means 60 minutes.

$60\text{ min }=360^(\circ)$

$1\text{ min }=(360)/(60)=6^(\circ)$

The minute hand move from 1:25 to 1:50, it means the minute have cover 25 minutes.

$25\text{ min }=(6* 25)^(\circ)$

$25\text{ min }=150^(\circ)$

Therefore minute hand moves 150 degree.

Multiply $(\pi)/(180)$ to convert degree into radian.

$150* (\pi)/(180)=(5\pi)/(6)$

Therefore the minute hand moves $(5\pi)/(6)$ radians.

Answer 2

Answer: How many radians does the minute hand move from 1:25 to 1:50?

Calculations are done as follows:

360 ° /60 minutes = 6° per minute
1:25 to 1:50 = 25 minutes

25 minutes x 6° per minute = 150°
150° (π/180) = 5π/6

While the pituitary gland is the master gand of the endocrine system, it controls the thyroid gland.

The pituitary gland can be found in the base of the brain, inferior to the hypothalamus. It is considered the gland that oversees the other endocrine organ glands. It regulates, control and manages every major gland in the body.

Explanation:

Unlike other organelles, chloroplasts and mitochondria contain their own genetic information in the form of A) DNA. B) RNA. C) purine. D) pyrimidines

Answers

The right answer is A) DNA.

During evolution, the mitochondria have retained their own genome, which, although very small compared to that of a bacterium, is essential for the proper functioning of these organelles. Confined within the mitochondria, organelles that produce cellular energy, the mitochondrial genome (mtDNA) is distinct from the DNA in the nucleus. The transmission of this DNA is generally called non-Mendelian because it is only transmitted by the mother.

Chloroplasts contain DNA grouped into nucleoids; each chloroplast can contain up to 100 copies of the genome. The DNA molecules of the chloroplast genome are generally linear or branched. The chloroplast genome is very small, 37 to 220 kb and usually contains about a hundred genes
