Hi, thank you for posting your question here at Brainly.

To find the velocity of light or any electromagnetic wave, we use the equation: v = wavelength * frequency. Substituting,

v = 0.5 m * 930 1/s
v = 465 m/s

Answer:

velocity of the wave is 465 m/sec.

Step-by-step explanation:

We have to calculate velocity of a wave with a frequency of 930 Hz and wave length of 0.50m

Since we know the formula V = f × λ

where V = velocity of a wave

f = frequency of wave

λ = wavelength of wave

Now we plug in the value.

V = 930 × 0.50 = 465 meter per second

Therefore, velocity of the wave is 465 m/sec.

In the Venn diagram, consider U = {whole numbers 1-100}
Dmitry [639]
The question is what numbers satisfy A ∩ C.

The symbol ∩ means intersection, .i.e. you need to find the numbers that belong to both sets A and C. Those numbers might belong to the set C or not, because that is not a restriction.

Then lets find the numbers that belong to both sets, A and C.

Set A: perfect squares from A to 100:

1^2 = 1
2^2 = 4
3^2 = 9
4^2 = 16
5^2 = 25
6^2 = 36
7^2 = 49
8^2 = 64
9^2 = 81
10^2 = 100

=> A = {1, 4, 9, 16, 25, 36, 49, 64, 81, 100}

Set C: perfect fourths

1^4 = 1
2^4 = 16
3^4 = 81

C = {1, 16, 81?

As you see, all the perfect fourths are perfect squares, so the intersection of A and C is completed included in A. this is:

A ∩ C = C or A ∩ C = 1, 16, 81

On the other hand, the perfect cubes are:

1^3 = 1
2^3 = 8
3^3 = 27
4^3 = 81

B = {1, 8, 27, 81}

That means that the numbers 1 and 81 belong to the three sets, A, B, and C.

In the drawing you must place the number 16 inside the region that represents the intersection of A and C only, and the numbers 1 and 81 inside the intersection of the three sets A, B and C.

2) For which value of P and W is P + W a rational number? P = 1/(sqrt(3)) And W = 1/(sqrt(6)) 2) P = 1/(sqrt(4)) and w = 1/(sqrt
fenix001 [56]

Answer:

  P = 1/(sqrt(4)) and w = 1/(sqrt(9))

Step-by-step explanation:

Only the roots of perfect squares are rational numbers. 2, 3, 6, and 10 are not perfect squares, so their roots are irrational. Both 4 and 9 are perfect squares, so their roots are rational. The sum of rational numbers is a rational number.

  \dfrac{1}{\sqrt{4}}+\dfrac{1}{\sqrt{9}}=\dfrac{1}{2}+\dfrac{1}{3}=\dfrac{5}{6}\quad\text{a rational number}

M is the midpoint of LN. L has coordinates (-3,-1) and M has coordinates (0,1). Find N coordinates.
miskamm [114]
To get the coordinates, we would use the midpoint formula (google it)

(X1-X2/2 , Y1+Y2/2)

(-3+0/2 , -1+1/2)

N: (-3/2,0)
