Answer:
This is false
Explanation:
This is why the answer to this question is false. If these types of objects (2 points connected) should pass through same sets of 3 points, irrespective of the order that each object was plotted, we will not get identical shapes created.
The shape that is going to be created will be dependent on the pattern/order that was involved in the plotting. If it was identical, then we will have identical shapes. But if the order during plotting is different then we will have different shapes created.
Thank you!
Explanation:
It is given that,
Frequency of vibration, f = 215 Hz
Amplitude, A = 0.832 mm
(a) Let T is the period of this motion. It is given by the following relation as :
![T=\dfrac{1}{f}](https://tex.z-dn.net/?f=T%3D%5Cdfrac%7B1%7D%7Bf%7D)
![T=\dfrac{1}{215}](https://tex.z-dn.net/?f=T%3D%5Cdfrac%7B1%7D%7B215%7D)
![T=4.65\times 10^{-3}\ s](https://tex.z-dn.net/?f=T%3D4.65%5Ctimes%2010%5E%7B-3%7D%5C%20s)
(b) Speed of sound in air, v = 343 m/s
It can be given by :
![v=f\times \lambda](https://tex.z-dn.net/?f=v%3Df%5Ctimes%20%5Clambda)
![\lambda=\dfrac{v}{f}](https://tex.z-dn.net/?f=%5Clambda%3D%5Cdfrac%7Bv%7D%7Bf%7D)
![\lambda=\dfrac{343\ m/s}{215\ Hz}](https://tex.z-dn.net/?f=%5Clambda%3D%5Cdfrac%7B343%5C%20m%2Fs%7D%7B215%5C%20Hz%7D)
![\lambda=1.59\ m](https://tex.z-dn.net/?f=%5Clambda%3D1.59%5C%20m)
Hence, this is the required solution.
Answer:
a) d = 6.0 m
Explanation:
Since car is accelerating at uniform rate then here we can say that the distance moved by the car with uniform acceleration is given as
![d = \frac{(v_f + v_i)}{2} \times t](https://tex.z-dn.net/?f=d%20%3D%20%5Cfrac%7B%28v_f%20%2B%20v_i%29%7D%7B2%7D%20%5Ctimes%20t)
here we know that
![v_f = 10 m/s](https://tex.z-dn.net/?f=v_f%20%3D%2010%20m%2Fs)
![v_i = 0](https://tex.z-dn.net/?f=v_i%20%3D%200)
![t = 1.2 s](https://tex.z-dn.net/?f=t%20%3D%201.2%20s)
now we will have
![d = \frac{(10 + 0)}{2}\times 1.2](https://tex.z-dn.net/?f=d%20%3D%20%5Cfrac%7B%2810%20%2B%200%29%7D%7B2%7D%5Ctimes%201.2)
![d = 5 \times 1.2](https://tex.z-dn.net/?f=d%20%3D%205%20%5Ctimes%201.2)
![d = 6.0 m](https://tex.z-dn.net/?f=d%20%3D%206.0%20m)
