Answer:
0
Explanation:
Displacement is a vector from initial to final point. Because initial and final point are the same, so displacement is 0.
At=v-u, where u=0
t= v/a=42/6 = 7
Answer: 7 seconds
n ecological terms, the carrying capacity of an ecosystem is the size of the population that can be supported indefinitely upon the available resources and services of that ecosystem. Living within the limits of an ecosystem depends on three factors:
<span>the amount of resources available in the ecosystem,the size of the population, and<span>the amount of resources each individual is consuming.</span></span>
Answer:
A) 2.09
B) -62.09°
Explanation:
If D = A+B+C then C = D - A - B
Converting both A and B to rectangular coordinates, we get:
A = [-4.07 , 4.68] and B = [6.19 , 3.87]
Replacing these values we can get the x and y components of C:
C = [0.98 , -1.85]

Its angle is:
Answer:
<h2>a) secondary oil recovery.</h2>
Explanation:
Secondary oil recovery is used when the pressure inside the well is to high, being not possible to do a primary oil recovery.
To do this method, high pressure is needed, like this case because it says that ''squirts strongly''.
On the other hand, tertiary oil recovery is used when another method is not possible. Hydraulic fracturing or fracking, it's develop with a horizontal drilling, which is not the case.
