A machine part is undergoing SHM with a frequency of 5.00Hz and amplitude 1.80cm . How long does it take the part to gofrom x=0

To solve this exercise we will use the expression of the displacement in the aromatic movement in the two given points. Thus we will find the value of time as a function of frequency. In the end we will replace that value and find the time taken,

The expression for the displacement of the object in simple harmonic motion is

$x = Acos(2\pi ft)$

At the initial position the value of x is zero,

$0 = Acost (2\pi ft_1)$

$cost (2\pi ft_1) = 0$

$2\pi ft_1 = \frac{\pi}{2}$

$t _1 = \frac{1}{4f}$

Now the expression for the displacement of the object in simple harmonic motion is

$x = Acos (2\pi ft)$

At the final position the value of x is -1.8cm

Replacing we have that

$-1.8=1.8cos(2\pi ft_2)$

$-1 = cos(2\pi ft_2)$

$t_2 = \frac{1}{2f}$

The total change in time will be

$t = t_2-t_1$

$t = \frac{1}{2f}-\frac{1}{4f}$

$t = \frac{1}{4f}$

Replacing the value of the frequency we have that

$t = \frac{1}{4*5}$

$t = 0.05s$

Therefore the time taken for the displacement in the interval of x=0 to x=-1.8 is 0.05s

Which are methods of reducing exposure to ionizing radiation? Check all that apply

MariettaO [177]

Ionising radiation (ionizing radiation) is radiation that carries enough energy to free electrons from atoms or molecules, thereby ionizing them. Ionizing radiation is made up of energetic subatomic particles, ions or atoms moving at high speeds (usually greater than 1% of the speed of light), and electromagnetic waves on the high-energy end of the electromagnetic spectrum.
