What is the frequency of yellow

Zina [86]

Answer:

5.131 × 10¹⁴ Hz

Step-by-step explanation:

Planck relation

$\large\boxed{E = hf}$

where:

E = Energy of the photon (J).
h = Planck's constant (J · s).
f = frequency of light produced (Hz).

Given values:

E = 3.4 × 10⁻¹⁹ J
h = 6.626 × 10⁻³⁴ J · s

Substitute the given values into the formula and solve for f:

$\implies 3.4 \times 10^{-19}=(6.626 \times 10^{-34})f$

$\implies f=\dfrac{3.4 \times 10^{-19}}{6.626 \times 10^{-34}}$

$\implies f=\dfrac{3.4}{6.626} \times \dfrac{10^{-19}}{10^{-34}}$

$\implies f=0.5131\times 10^{(-19-(-34))}$

$\implies f=0.5131 \times 10^{15}$

$\implies f=5.131 \times 10^{14}$

Solve for c.

Mrrafil [7]

Answer:

The answer is c = $\frac{d+ab}{a}$

Solution:

When a sum of two numbers is multiplied by a number, the number can be distributed to the addends separately, then adding the products together will produce the same result as multiplying sum by the number. This property is called distributive property of multiplication.

To find the value of, a(c-b)=d

On applying the distributive property of multiplication which is $[a\times(b+c)=a\times b+a\times c]$

Here we get,

$a\times(c-b)=a\times c-a\times b$

So the equation will be,

$a\times c-a\times b=d$

$ac-ab=d$

$ac=d+ab$

$c=\frac{d+ab}{a} or \frac{d}a+\frac{ab}{a}$

A rectangular bookcase 60 inches long and 30 inches wide. How long is the diagonal? Round to the nearest inch.

Talja [164]

The diagonal is about 180 inches long,because 60×30 equals 1800.Then,since you can't round a number under 5,the answer is about 180 inches long.

Can someone help me with 7?

Elanso [62]

Solving the equation for y puts it in slope-intercept form.

$3x-5y=5\qquad\text{given equation}\\3x-5=5y\qquad\text{add 5y-5}\\y=\dfrac{3}{5}x-1\qquad\text{divide by 5}$

This tells you one point can be plotted on the y-axis at y=-1. Another point can be plotted 3 units up and 5 units to the right of that one, at (5, 2). The graph is the line through those points.

Since you're asked to plot at least 3 points, your third point could be 5 units left and 3 units down from the first one, at (-5, -4).
