Frequency is the Number of Waves passing through a Point in One Second
Given : The Frequency of the Wave is : 700 Hz
Given : The Wavelength of the Wave is : 6 meter
⇒ In One second 700 waves of Wavelength 6 meter cross the point
⇒ In One second the First wave travels : 700 × 6 meters
⇒ In One second the First wave travels : 4200 meter
⇒ The Speed of the wave is : 4200 m/sec
Answer:
Step-by-step explanation:
12 x 3=36 yx
12x2x3= 72 x*y
6 7/8. You must get a common denominater. I used 8, which multiplis 4 times 2. Then the top number is multiplied by 2 to get 2/8. Now add the tops and bottoms to get 7/8. Now add the whole numbers to get 6.
3c=9
$3 per comic book (c) equals the total amount of money spent, $9.
You can solve this expression by dividing both sides by 3.
c=3, which means that each book costs $3.
I hope this helps :)
Answer:
n = (4 i)/sqrt(11) or n = -(4 i)/sqrt(11)
Step-by-step explanation:
Solve for n:
11 n^2 + 16 = 0
Subtract 16 from both sides:
11 n^2 = -16
Divide both sides by 11:
n^2 = -16/11
Take the square root of both sides:
Answer: n = (4 i)/sqrt(11) or n = -(4 i)/sqrt(11)
