Friction will slow down the moving object
As per above given data
initial velocity = 19.3 km/s
final velocity = - 18.8 km/s
now in order to find the change in velocity
![\Delta v = v_f - v_i](https://tex.z-dn.net/?f=%5CDelta%20v%20%3D%20v_f%20-%20v_i)
![\Delta v = -18.8 - 19.3](https://tex.z-dn.net/?f=%5CDelta%20v%20%3D%20-18.8%20-%2019.3)
![\Delta v = -38.1 km/s](https://tex.z-dn.net/?f=%5CDelta%20v%20%3D%20-38.1%20km%2Fs)
![\Delta v = -3.81 * 10^4 m/s](https://tex.z-dn.net/?f=%5CDelta%20v%20%3D%20-3.81%20%2A%2010%5E4%20m%2Fs)
Part b)
Now we need to find acceleration
acceleration is given by formula
![a = \frac{\Delta v}{\Delta t}](https://tex.z-dn.net/?f=a%20%3D%20%5Cfrac%7B%5CDelta%20v%7D%7B%5CDelta%20t%7D)
given that
![\Delta v =- 3.81 * 10^4 m/s](https://tex.z-dn.net/?f=%5CDelta%20v%20%3D-%203.81%20%2A%2010%5E4%20m%2Fs)
![\Delta t = 2.07 years = 6.53 * 10^7 s](https://tex.z-dn.net/?f=%5CDelta%20t%20%3D%202.07%20years%20%3D%206.53%20%2A%2010%5E7%20s)
now the acceleration is given as
![a = \frac{-3.81 * 10^4}{6.53 * 10^7}](https://tex.z-dn.net/?f=a%20%3D%20%5Cfrac%7B-3.81%20%2A%2010%5E4%7D%7B6.53%20%2A%2010%5E7%7D)
![a = - 5.84 * 10^{-4}m/s^2](https://tex.z-dn.net/?f=a%20%3D%20-%205.84%20%2A%2010%5E%7B-4%7Dm%2Fs%5E2)
so above is the acceleration
Answer:
: carbon tetrabromide
Explanation:
is a covalent compound because in this compound the sharing of electrons takes place between carbon and bromine. Both the elements are non-metals. Hence, it will form covalent bond.
The naming of covalent compound is given by:
1. The less electronegative element is written first.
2. The more electronegative element is written second. Then a suffix is added with it. The suffix added is '-ide'.
3. If atoms of an element is greater than 1, then prefixes are added which are 'mono' for 1 atom, 'di' for 2 atoms, 'tri' for 3 atoms and so on.
Hence, the correct name for
is carbon tetrabromide.
The strength of a field force changes with distance from the sourceof the field-stronger closer to the source, weaker farther away from the source. The source can be either a mass, a charged particle, or a magnetic pole.
