Explanation:
F net of sled = Tension force by rope - Kinetic friction between ground.
F normal of sled = mg = (67kg)(9.81kg/m^2) = 657.27N.
Kinetic friction = 0.18 (I cannot see the value) * Normal force of sled = 0.18 * 657.27N = 118.31N
So F net of sled = 800N - 118.31N = 681.69N.
(I cannot see what the question is asking for, please check on your own!)
Line c is at rest . line a is going in a positive direction . line b is going in a negative direction . line d is negative too
<span>An ecosystem can only sustain so many organisms. That limit would be its carrying capacity. If the population goes above that number then other factors will cause the population to crash and then rebound to a constant level. </span>
Distance = (30+40+50) = 120 km
It's back where it started, so displacement = zero
The forest ecosystem will regain back its natural ecology
compared to burning of the forest and other illegal activities done to the
forest. And also, some of the animals living in that forest will live and those
that are endangered will not be threatened.
