D). Impulse causes a change in momentum.
The value of the thrust developed by the engine of a boeing 777 in N and Kgf are ;
i) 376616N
ii) 38430Kgf
<h3>What is force?</h3>
Force is a push or a pull. The reactive force always serve to balance the applied force. We are here asked to convert the the thrust developed by the engine of a boeing 777 which is about 85400 lbf to the following units;
i) N
ii)kgf
Thus;
1 Ib = 0.45 Kg
1 lbf = 0.45 Kg * 9.8 m/s^2 = 4.41 N
We know that;
1 lbf = 4.41 N
85400 lbf = 85400 lbf. * 4.41 N/1 lbf
= 376616N
Again;
1 lbf = 0.45 Kgf
85400 lbf = 85400 lbf * 0.45 Kgf/1 lbf
= 38430Kgf

Answer:
Positive velocity changing velocity and acceleration.
Explanation:
Answer:
I believe the answer is D.
Explanation:
It would have been helpful if there had been more information included with this problem, but it would make sense that the answer is D. If there is a winter between time 1 and 3, bison that are not well-suited to the weather, (skinny and smooth) will die off, and only the ones well-suited to winter weather will survive to produce offspring.
