Answer:
v = c / n (n = 1 for air)
v = c / 1.33 = 3 * 10E8 m/s / 1.33 = 2.25 * 10E8 m/s
The location of the point F that partitions a line segment from D to E (
), that goes from <u>negative 4</u> to <u>positive 5,</u> into a 5:6 ratio is fifteen halves (option 4).
We need to calculate the segment of the line DE to find the location of point F.
Since point D is located at <u>negative -4</u> and point E is at <u>positive 5</u>, we have:
Hence, the segment of the line DE () is 9.
Knowing that point F partitions the line segment from D to E () into a <u>5:6 ratio</u>, its location would be:
Therefore, the location of point F is fifteen halves (option 4).

Answer:
total capacity = 135,168,000,000 bytes
Explanation:
given data
hard disk divided = 1100 sectors
cylinders = 40,000
block holds = 512 bytes
rotating rate = 4800 rpm
consider average seek time = 12 msec
to find out
total capacity of this disk
solution
total capacity of this disk are express as
total capacity = hard disk divided × cylinder block holds × average seek time ÷ 2
put here value we get
total capacity = 1100 × 40000 × 512 × 6
total capacity = 135,168,000,000 bytes
Answer: Frequency
Explanation: The velocity of a wave is the product of wavelength and frequency. That is to say:
Hence, the frequency associated with the tsunami is needed to calculate the velocity.
The answer is Density. The Density of the <span>glass is measured with bromoform and bromobenzene mixtures in a column. </span>Density measurement<span> is done using Density gradient </span>columns. It is a <span> temperature-controlled density </span>column<span> containing a </span>mixture<span> of b</span>romobenzene<span> and </span>bromoform.
