Answer:
The outer surface of bone is called the periosteum (say: pare-ee-OSS-tee-um). It's a thin, dense membrane that contains nerves and blood vessels that nourish the bone. The next layer is made up of compact bone. This part is smooth and very hard.
The answer is A. Solids have both definite shape and denfinite volume.
Answer: 1) a = 9.61m/s² pointing to west.
2) (a) Δv = - 37.9km/s
(b) a = - 6.10⁷km/years
Explanation: Aceleration is the change in velocity over change in time.
1) For the plane:
![a=\frac{\Delta v}{\Delta t}](https://tex.z-dn.net/?f=a%3D%5Cfrac%7B%5CDelta%20v%7D%7B%5CDelta%20t%7D)
![a=\frac{125}{13}](https://tex.z-dn.net/?f=a%3D%5Cfrac%7B125%7D%7B13%7D)
a = 9.61m/s²
The plane is moving east, so velocity points in that direction. However, it is stopping at the time of 13s, so acceleration's direction is in the opposite direction. Therefore, acceleration points towards west.
2) Total change of velocity:
![\Delta v = v_{f}-v_{i}](https://tex.z-dn.net/?f=%5CDelta%20v%20%3D%20v_%7Bf%7D-v_%7Bi%7D)
![\Delta v = -17.1-(+20.8)](https://tex.z-dn.net/?f=%5CDelta%20v%20%3D%20-17.1-%28%2B20.8%29)
km/s
The interval is in years, so transforming seconds in years:
v = ![\frac{-37.9}{3.15.10^{-7}}](https://tex.z-dn.net/?f=%5Cfrac%7B-37.9%7D%7B3.15.10%5E%7B-7%7D%7D)
km/years
Calculating acceleration:
![a=\frac{-12.03.10^{-7}}{2.01}](https://tex.z-dn.net/?f=a%3D%5Cfrac%7B-12.03.10%5E%7B-7%7D%7D%7B2.01%7D)
![a=-6.10^{7}](https://tex.z-dn.net/?f=a%3D-6.10%5E%7B7%7D)
Acceleration of an asteroid is a = -6.10⁷km/years .
Explanation:
36-4/4= 9 m/squared. meter per squared.
acceleration unit is meter per second Square.equation is velocity by time.for average final(36) minus initial(4)
The frequency of a wave is equal to the linear speed divided the wavelength. so in equation form.
f = v / l
so the wavlength
l = v / f
where f is the frequency
v iss the linear speed
l is the wavelength
l = ( 5100 m/s ) / ( 2.2 Mhz ) ( 10^6 hz / 1 Mhz )
f = 0.0023 m
f = 2.3 mm
