Calculate the frequency in hertz of photons of light with energy of 8.10 × 10-19 J.
stira [4]
The Planck–Einstein relation E=hv gives that E, the photon energy, is equal to h, Planck's constant, times <span>ν</span>, the frequency.

We can solve the equation in terms of frequency to get
v= \dfrac{E}{h}

We substitute our given energy, 8.10 \times 10^{-19} J, and Planck's constant, 6.626 \times 10^{-34} Js.

v= \dfrac{8.10 \times 10^{-19} J}{6.626 \times 10^{-34} Js}=1.22 \times 10^{15} s^{-1}=1.22 \times 10^{15} Hz

Write an equation for the line on the graph below:
wolverine [178]

Answer:

This line is a horizontal line, so it has an equation y=n, where n is a number.

In this case,  because the y intercept is (0,2) the equation is y=2.

Let me  know if this helps!

F(x)= (3/4)x+12 what is the y-intercept of f^-1(x)
STatiana [176]

Answer:

y = (3/4)x + 12

x = (3/4)y + 12

(3/4)y + 12 = x

(3/4)y = x - 12

3y = 4x - 48

y = (4/3)x - 16

f^-1(x) = (4/3)x - 16

the y intercept is -16

Anchorage is a city in country Alaska.

Based on 2010 data, Anchorage has a population of 291826 people and the area coverage of the city is 1961.1 square miles.

We are asked to determine the population density of Anchorage city.

Therefore, the number of people living per unit square miles of Anchorage is given by \frac{291826}{1961.1} =148.8 ≈149 people/ sq. miles. (Answer)
