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:
sorry I can't help because I don't now about biology
It’s more useful because you can see that animals eat more then one type of food and that if one animal dies out that you can see the animal that eats that animal can still love because there’s other animals it eats
Answer:
Molecular, Microscopic, Cell, Tissue and Organ levels
Explanation:
The natural strength production needed for skeletal muscle to function occurs at the molecular level. You can develop a better knowledge of the properties of cells and tissues by simply studying the molecular systems common to the cells in question. The different muscular level down to myofilaments are:
-
Molecular level — actin and myosin
- Microscopic level — sarcomere and myofibrils
- Cell level — myoblasts and myofibers
- Tissue level — neuromuscular intersections and fascicles
- Organ level — The key skeletal muscles of the body
