Answer:
the number of neutrons and protons in an atom
Answer:
to be honest I'm not sure
Answer:
Accurate
Explanation:
Accuracy deals with the nearness of the measured values to the true value.
Precision is the ability to reproduce a certain result in a repeated fashion.
- From the given masses of the 5-lb bags, we see that the mean value of the measurement is 5.1-lb
- This value is very close to the original mass of the bag which is 5-lb bags.
- We can say the reading is accurate
The reading is not precise because, the same weight is not reproduced. Different values of weight was reported from each of the measurement process.
The equation of the motion of this object is ![\mathbf{y = 3 cos \Big [ \dfrac{ \pi}{2}(t -2) \Big ] }](https://tex.z-dn.net/?f=%5Cmathbf%7By%20%3D%203%20cos%20%5CBig%20%5B%20%5Cdfrac%7B%20%5Cpi%7D%7B2%7D%28t%20-2%29%20%5CBig%20%5D%20%7D)
<h3>What is oscillation?</h3>
An oscillation in a waveform is a periodic set of vibrations an object in the medium produces.
From the parameters given:
- The spring is pulled 3 feet down ward from the origin(equilibrium position) = -3
- Time to complete one oscillation = 4 seconds
The angular velocity can be computed by using the formula:
The amplitude A from the oscillation is:
It implies that the vertical shift (D) is:
However, by using the formula of the general form of a sinusoidal equation, we have:
![\mathbf{y = A cos \Big [ \dfrac{2 \pi}{4}(t -2) \Big ] + 0}](https://tex.z-dn.net/?f=%5Cmathbf%7By%20%3D%20A%20cos%20%5CBig%20%5B%20%5Cdfrac%7B2%20%5Cpi%7D%7B4%7D%28t%20-2%29%20%5CBig%20%5D%20%2B%200%7D)
