Frequency is inversely proportional to wavelength.

Wavelength is the spacial period, and more generally the frequency is inversely proportional to the period.

If the wave's speed if c, then f=c/l where l is the wavelength.

Bingel [31]

Mike enters a revolving door that is not moving. Mike should push at the edge of the door where it is largest distance from the pivot point in order to produce a torque with the least amount of force. Torque is equal to t = force x distance.

A spring with a spring constant of 165 N/m is attached to a 2.0 kg mass and set into motion.

marin [14]

Explanation:

We have,

Spring constant of the spring, k = 165 N/m

Mass, m = 2 kg

It is required to find the period of the mass-spring system. For the spring mass system, the period is given by :

$T=2\pi \sqrt{\dfrac{m}{k} }\\\\T=2\pi \sqrt{\dfrac{2}{165} }\\\\T=0.69\ s$

The frequency of vibration is reciprocal of its time period. So,

$f=\dfrac{1}{T}\\\\f=\dfrac{1}{0.69}\\\\f=1.44\ Hz$

So, the period of the mass-spring system is 0.69 s and frequency is 1.44 Hz.

The uncertainty in position of a proton confined to the nucleus of an atom is roughly the diameter of the nucleus. If this diame

irakobra [83]

<u>Answer:</u> The uncertainty in proton's momentum is $1.3\times 10^{-20}kg.m/s$

<u>Explanation:</u>

The equation representing Heisenberg's uncertainty principle follows:

$\Delta x.\Delta p\geq \frac{h}{2\pi}$

where,

$\Delta x$ = uncertainty in position = d = $7.8\times 10^{-15}m$

$\Delta p$ = uncertainty in momentum = ?

h = Planck's constant = $6.627\times 10^{-34}kgm^2/s^2$

Putting values in above equation, we get:

$\Delta p=\frac{6.627\times 10^{-34}kgm^2/s^2}{2\times 3.14\times 7.8\times 10^{-15}m}\\\\\Delta p=1.3\times 10^{-20}kg.m/s$

Hence, the uncertainty in proton's momentum is $1.3\times 10^{-20}kg.m/s$
