Answer:
![T=2.5*10^{-3}s](https://tex.z-dn.net/?f=T%3D2.5%2A10%5E%7B-3%7Ds)
Explanation:
From the question we are told that:
Beat frequency ![F_b=4](https://tex.z-dn.net/?f=F_b%3D4)
Frequency ![F=400Hz](https://tex.z-dn.net/?f=F%3D400Hz)
Generally the equation for Frequency of the violin is mathematically given by
![f_v=F_b+F](https://tex.z-dn.net/?f=f_v%3DF_b%2BF)
![f_v=4+400Hz](https://tex.z-dn.net/?f=f_v%3D4%2B400Hz)
![f_v=404Hz](https://tex.z-dn.net/?f=f_v%3D404Hz)
Therefore the period of the violin string oscillations is
![T=\frac{1}{f_v}](https://tex.z-dn.net/?f=T%3D%5Cfrac%7B1%7D%7Bf_v%7D)
![T=\frac{1}{404}](https://tex.z-dn.net/?f=T%3D%5Cfrac%7B1%7D%7B404%7D)
![T=2.5*10^{-3}s](https://tex.z-dn.net/?f=T%3D2.5%2A10%5E%7B-3%7Ds)
Answer: 1
Explanation: The highest eccentricity an ellipse can have is '1', a straight line.
Answer:
v = 10.46 m/s
x = 30.134 m from house
Explanation:
given data
speed = 3.05 m/s
time = 7 s
height = 40.8 mm
solution
we get here first time required to fall that is t
t =
..................1
t = 2.88 s
now we take here initial speed that is v
so v × t = 3.05 × ( t+ 7)
v = ![\frac{3.05\times (2.88 + 7)}{2.88}](https://tex.z-dn.net/?f=%5Cfrac%7B3.05%5Ctimes%20%282.88%20%2B%207%29%7D%7B2.88%7D)
v = 10.46 m/s
and
when she catch the bagel henrietta was at
x = 3.05 × ( 2.88 + 7)
x = 30.134 m from house
