A bulldozer does 15,000 J of work lifting dirt 15 m up to get it out of a hole. How much force did the bulldozer use to accompli
nika2105 [10]

Answer:

<h3>The answer is 3000 N</h3>

Explanation:

The amount of force can be found by using the formula

f =  \frac{w}{d}  \\

w is the workdone

d is the distance

From the question we have

f =  \frac{15000}{5}  \\

We have the final answer as

<h3>3000 N</h3>

Hope this helps you

If the wavelength of purple light is 400 x 10^-9 m, what is the frequency?
FromTheMoon [43]

The frequency : a) 7.5 x 10¹⁴ /s

<h3>Further explanation</h3>

Radiation energy is absorbed by photons

The energy in one photon can be formulated as

\large{\boxed{\bold{E\:=\:h\:.\:f}}}

Where

h = Planck's constant (6,626.10⁻³⁴ Js)

f = Frequency of electromagnetic waves  (/s or Hz)

f = c / λ

c = speed of light

= 3.10⁸  m/s

λ = wavelength

The wavelength(λ) of purple light is 400 x 10⁻⁹ m, so the frequency :

\tt f=\dfrac{c}{\lambda}\\\\f=\dfrac{3.10^8~m/s}{4.10^{-7}m}\\\\f=\boxed{\bold{7.5.10^{14}}/s}
