Answer:
1) 945000 m
2) 6.11 miles/hour
3) 3.52 seconds
Explanation:
1. Speed is the time rate of change of distance, it is the ratio of distance to time. Speed is given by the equation:
![speed(S)=\frac{distance(d)}{time(t)}](https://tex.z-dn.net/?f=speed%28S%29%3D%5Cfrac%7Bdistance%28d%29%7D%7Btime%28t%29%7D)
Given that:
Time (t) = 9 hours and Speed (S) = 105 km/h
![S=\frac{d}{t}\\ d=S*t=105*9=945km=945000m](https://tex.z-dn.net/?f=S%3D%5Cfrac%7Bd%7D%7Bt%7D%5C%5C%20d%3DS%2At%3D105%2A9%3D945km%3D945000m)
2) Time (t) = 0.9 hours and distance (d) = 5.5 miles
![S=\frac{d}{t}\\ S=\frac{5.5}{0.9} =6.11miles/hour](https://tex.z-dn.net/?f=S%3D%5Cfrac%7Bd%7D%7Bt%7D%5C%5C%20S%3D%5Cfrac%7B5.5%7D%7B0.9%7D%20%3D6.11miles%2Fhour)
3) Acceleration it is the ratio of velocity to time. Acceleration is given by the equation:
![Accceleration(a)=\frac{Final,velocity(u)-initial, velocity(v)}{time(t)}](https://tex.z-dn.net/?f=Accceleration%28a%29%3D%5Cfrac%7BFinal%2Cvelocity%28u%29-initial%2C%20velocity%28v%29%7D%7Btime%28t%29%7D)
Given that :
a = 4.2 m/s² , u = 18.9 m/s and v = 33.7 m/s
![a=\frac{v-u}{t}\\ t=\frac{v-u}{a}\\ t=\frac{33.7-18.9}{4.2}=3.52s](https://tex.z-dn.net/?f=a%3D%5Cfrac%7Bv-u%7D%7Bt%7D%5C%5C%20t%3D%5Cfrac%7Bv-u%7D%7Ba%7D%5C%5C%20t%3D%5Cfrac%7B33.7-18.9%7D%7B4.2%7D%3D3.52s)
Answer: water potential is the measure of the energy of water to move from one area to another.
Explanation: water potential effects osmosis in a way that water needs to move through membrane and for this movement it requires pressure which makes water potential high so water movement will be faster across the membrane. Water potential determines water movement in osmosis that water move from high water potential region to low water potential region. If water potential is high inside than outside, then water movement to outside will be more.
If water potential is high outside than inside then water will move more inside. If water potential is the same in and outside then water movement inside and outside will be same and this will be called as equilibrium.
Answer:
non-polar
Explanation:
Glycerol has three polar Oxygen-Hydrogen bonds but these are attached to hydrocarbon chains which are relatively non-polar.
The conclusion needs to <u>be backed up by more </u><u>evidences</u> only then scientists make a claim.
Finding one type of bacteria that can survive in an oxygen-free environment does not prove that many other organisms can as well. It is important to understand the biological processes that give <u>organisms the traits that enable them to live in settings devoid of </u><u>oxygen</u>. More data from many groups of species are required to support the statement.
<h3>In what all conditions can bacteria thrive?</h3>
Although bacteria can survive at higher and lower temperatures than humans, they thrive in an environment that is <u>warm, wet, protein-rich, and</u><u> pH neutral</u><u> or </u><u>slightly acidic</u><u>.</u> However, there are several exceptions. While certain bacteria can <u>survive in extremely hot or cold </u><u>environments</u>, others can endure excessively acidic or salty environments. The danger zone, or the temperature range <u>between 41 and 135 degrees Fahrenheit</u>, is where most pathogenic bacteria thrive.
