Answer:
d) An object that is speeding up always has a positive acceleration, regardless of the direction it travels.
Explanation:
a ) a) An object that is slowing down while traveling in the negative x-direction always has a positive acceleration.
It has negative acceleration in the negative x-direction.
b) An object that is speeding up while traveling in the negative x-direction always has a positive acceleration.
It has a positive acceleration in the negative x-direction'
c) An object that is slowing down always has a negative acceleration, regardless of the direction it travels.
It has a positive acceleration in opposite direction.
e ) An object that is slowing down always has a positive acceleration, regardless of the direction it travels.
It has a positive acceleration only in opposite direction .

According to the research, the correct answer is that higher latitudes are conditions that can cause hurricanes to change direction.
<h3>What are hurricanes?</h3>
It is a meteorological phenomenon that usually originates in the tropical areas of the lower atmosphere, being a wind of extraordinary force that forms a whirlwind.
In this sense, the direction of these winds is influenced by the rotation of the Earth (Coriolis effect) and that as they move a little towards the higher latitudes, the direction winds are reversed and blow from west to east.
Therefore, we can conclude that the condition that affects the direction of hurricanes is when these tropical phenomena reach the highest latitudes.

Explanation:
Given that,
Radius in which the satellite orbits, r = 6588 km
Solution,
The centripetal force acting on the satellite is balanced by the gravitational force acting between earth and the satellite. Its expression can be written by :
![\dfrac{GmM}{r^2}=\dfrac{mv^2}{r}](https://tex.z-dn.net/?f=%5Cdfrac%7BGmM%7D%7Br%5E2%7D%3D%5Cdfrac%7Bmv%5E2%7D%7Br%7D)
, M is the mass of earth
![v=\sqrt{\dfrac{6.67259\times 10^{-11}\times 5.98\times 10^{24}}{6588\times 10^3}}](https://tex.z-dn.net/?f=v%3D%5Csqrt%7B%5Cdfrac%7B6.67259%5Ctimes%2010%5E%7B-11%7D%5Ctimes%205.98%5Ctimes%2010%5E%7B24%7D%7D%7B6588%5Ctimes%2010%5E3%7D%7D)
v = 7782.53 m/s
Let t is the time required to complete one orbit. It can be calculated as :
![t=\dfrac{d}{v}](https://tex.z-dn.net/?f=t%3D%5Cdfrac%7Bd%7D%7Bv%7D)
![t=\dfrac{2\pi r}{v}](https://tex.z-dn.net/?f=t%3D%5Cdfrac%7B2%5Cpi%20r%7D%7Bv%7D)
![t=\dfrac{2\pi \times 6588\times 10^3}{7782.53}](https://tex.z-dn.net/?f=t%3D%5Cdfrac%7B2%5Cpi%20%5Ctimes%206588%5Ctimes%2010%5E3%7D%7B7782.53%7D)
t = 5318.78 seconds
or
t = 1.47 hour
Therefore, this is the required solution.
