Sam is rowing a boat away from a dock. the graph shows the relationship between time and Sam's distance from the dock. evaluate the function for an input of 3.


A. after 3 minutes, Sam is 3 meter from the dock.


B. after 40 minutes, Sam is 40 meters from the dock.


C. after 40 minutes, Sam is 3 meters from the dock.


D. after 3 minutes, Sam is 40 meters from the dock.

Given parameters:

Distance  = 5km

Time taken = 45 minutes

Unknown:

Speed  = ?

Solution:

Speed is a physical quantity.

It is given as;

   Speed  = [tex]\frac{distance}{time}[/tex]

Since the unknown is speed;

     convert the time given to hours;

         60min  = 1hr

         45min = [tex]\frac{45}{60}[/tex]   = [tex]\frac{3}{4}hr[/tex]

So, speed  = [tex]\frac{5}{\frac{3}{4} }[/tex]   = 5 x [tex]\frac{4}{3}[/tex]  

                        = [tex]\frac{20}{3}[/tex]km/hr

Explanation:

Canada is the second-largest country in the world, but its population is not what would be expected for such a vast territory, in fact, Canada is a country with low population density. The majority of the population in this country is concentrated in the southern, southeastern, and southwestern part, while the rest of the territory is mostly empty. There are multiple reasons for this uneven population concentration, with the major being the climate, economy, and connectivity.

The aforementioned areas where the population is concentrated are the only ones that provide relatively good living conditions. These are the only parts of the country where agriculture is possible. Coming out on sea (that doesn't freeze in winter) is very beneficial for trade but also makes the climate milder. And last but not least, these are the areas that border the United States, the biggest economy in the world, which in turn has a big influence on the high development of the Canadian economy near the border.

Explanation:

Topography; is not correct because despite its influence it is not the detrimental factor as to what type of vegetation will grow where.

Wildlife; is not correct because the wildlife depends on the type of vegetation, not the other way around.

Inhabitants; is not correct because the people may or may not influence an area's vegetation, but at the end of the day they can not replace it vegetation that can not prosper in the given conditions.

Climate; is correct because the climate is the most important factor that determines how would the vegetation be distributed around the world, and this can easily be seen by the types of vegetation in correlation with the climate zones.

Answer:

At convergent plate boundaries, oceanic crust is often forced down into the mantle where it begins to melt. Magma rises into and through the other plate, solidifying into granite, the rock that makes up the continents. Thus, at convergent boundaries, continental crust is created and oceanic crust is destroyed.

Answer:

look at explanation :p

Explanation:

At convergent plate boundaries, oceanic crust is often forced down into the mantle where it begins to melt. Magma rises into and through the other plate, solidifying into granite, the rock that makes up the continents. Thus, at convergent boundaries, continental crust is created and oceanic crust is destroyed. Or another way to say it is,  The plate boundaries are the locations where the plates shares either a divergent, transform or convergent type of boundaries. The convection current that is generated in the mantle region of the earth's interior led to the breakdown of the lithosphere into various large and small plates. At the divergent plate boundaries, the magma rises upward from the interior of the earth, causing upwelling of the mantle, and thereby adding new materials to the crust along the mid-oceanic ridge. At the convergent plate boundaries, the plates collides and denser one sinks to the interior of the earth, causing the mantle to shrink. At the transform plate boundaries, the plates are conserved and the mantle remains unchanged.
