You should calculate 40 kg and the radius 3mm.
Answer:
U = 8.30×10-⁹J
Explanation:
m1 = m2 = 5.00kg masses of the spheres
d = 15.0cm = 15×10-²m
r = 5.10cm = 5.10×10-²m
R = d + r = 15×10-² + 5.10×10-²
R = 20.10 ×10-²m = 0.201m
G = 6.67×10-¹¹Nm²/kg²
U = Gm1×m2/R = potential energybetween the spheres
U = 6.67×10-¹¹×5.00×5.00/0.201
U = 8.30×10-⁹J
The rate of altitude increase is equivalent to the vertical component of the pilot's velocity. Let the first pilot's velocity be A and the second's be B.
Ay = Asin(∅)
Ay = 400sin(30)
Ay = 200 mph
By = Bsin(∅)
By = 300sin(40)
By = 192.8 mph
200 - 192.8 = 7.2 mph
The first pilot gains altitude faster by 7.2 mph than the second pilot.
The correct answers should be<span> the hares will multiply indiscriminately and destroy the ecosystem and </span><span>the native herbivores will experience increased competition for resources.
Since the hares wouldn't have predators, and they are famous for rapid breeding, they would overpopulate the ecosystem. On the other hand, the native animals would have to compete with this population of hares for food and would have less for for themselves.</span>
