Answer:
Probs paper cuz the rest are metals
Answer:
1-D(carbon dioxide, water and sunlight)
2-D(parasitism)
3-C(competition)
Explanation:
hope it helps
Answer:
84 kj/min = 1.4 kj/sec
Power Out / Power In = Heat Out / Heat In - Coefficient of Performance
1.4 kj/sec / 1.2 kj/sec = 1.17 = COP
Answer:
T = 34.54 N
Explanation:
First we find the buoyant force acting on the sphere, due to displaced water. For that purpose, we need to find the volume of water displaced by the sphere.
Volume of Water Displaced = V = (Mass of Sphere)/(Density of metal)
V = 4.7 kg/(4000 kg/m³)
V = 0.001175 m³
Now, the buoyant force is given as:
F = (Density of Water)(V)(g)
F = (1000 kg/m³)(0.001175 m³)(9.8 m/s²)
F = 11.52 N
Now, we find the weight of the sphere:
W = mg = (4.7 kg)(9.8 m/s²)
W = 46.06 N
Since, both the tension force (T) and buoyant force act in upward direction, while the weight of sphere act in downward direction. Therefore,
W = T + F
T = W - F
T = 46.06 N - 11.52 N
<u>T = 34.54 N</u>
