. In a physics lab, you attach a 0.200-kg air-track glider to the end of an ideal spring of negligible mass and start it oscilla

cluponka [151]

Answer:

Spring constant, k = 1.16 N/m

Explanation:

It is given that,

Mass of the air track, m = 0.2 kg

Time, t = 2.6 s

Let T is the time period of the spring. The expression for the time and spring constant is given by :

$T=2\pi \sqrt{\dfrac{m}{k}}$

$k=\dfrac{4\pi^2m}{T^2}$

$k=\dfrac{4\pi^2\times 0.2}{(2.6)^2}$

k = 1.16 N/m

So, the spring’s force constant is 1.16 N/m. Hence, this is the required solution.

A certain kind of light has a wavelength of 850 nm. What is the frequency of this light in hz?.

eduard

So, the frequency of that light approximately $\sf{\bold{3.53 \times 10^{14} \: Hz}}$

<h3>Introduction</h3>

Hi ! I will help you to explain the relationship between velocity of electromagnetic waves in a vacuum with frequency and wavelength. We all know that all of the type of electromagnetic wave, will have the same velocity as the speed of light (because the value is a constant), which is 300,000 km/s or $\sf{3 \times 10^8}$ m/s. As a result of this constant property, <u>the shorter the wavelength, the greater the value of the electromagnetic wave frequency</u>. This relationship can also be expressed in this equation:

$\boxed{\sf{\bold{c = \lambda \times f}}}$

With the following condition :

c = the constant of the speed of light in a vacuum ≈ $\sf{3 \times 10^{8} \: m/s}$ m/s
$\sf{\lambda}$ = wavelength (m)
f = electromagnetic wave frequency (Hz)

<h3>Problem Solving</h3>

We know that :

c = the constant of the speed of light in a vacuum ≈ $\sf{3 \times 10^{8} \: m/s}$ m/s
$\sf{\lambda}$ = wavelength = 850 nm = $\sf{8.5 \times 10^2 \times 10^{-9}}$ m = $\bold{8.5 \times 10^{-7} \: m}$

What was asked :

f = electromagnetic wave frequency = ... Hz

Step by step :

$\sf{c = \lambda \times f}$

$\sf{3 \times 10^8 = 8.5 \times 10^{-7} \times f}$

$\sf{f = \frac{3 \times 10^8}{8.5 \times 10^{-7}}}$

$\sf{f \approx 0.353 \times 10^{8 -(-7)}}}$

$\sf{f \approx 3.53 \times 10^{-1} \times 10^{15}}$

$\boxed{\sf{f \approx 3.53 \times 10^{14} \: Hz}}$

<h3>Conclusion :</h3>

So, the frequency of that light approximately $\sf{\bold{3.53 \times 10^{14} \: Hz}}$

When a particular wire is vibrating with a frequency of 4.7 hz, a transverse wave of wavelength 71.9 cm is produced. determine t

nikdorinn [45]

The relationship between frequency, wavelength and speed of a wave is given by
$v=\lambda f$
where
v is the wave speed
$\lambda$ is its wavelength
f is its frequency

for the wave in our problem, $f=4.7 Hz$ and $\lambda=71.9 cm=0.719 m$ , so the speed of the wave is (using the previous equation)
$v=\lambda f = (0.719 m)(4.7 Hz)=3.38 m/s$
