The first is mutualism
The second is commensalism i believe (or mutualism)
The third is Parasitism
Answer:e
Explanation:
Given
Area of parallel plates is A
distance between plates is d
Potential difference between Plates is V
Capacitance is given by
If separation is doubled then capacitance become half
Electrical energy stored in the capacitor is given by
When distance is doubled
Therefore Energy is halved
Answer:
1. 0.574 kJ/kg
2. 315.7 MW
Explanation:
1. The mechanical energy per unit mass of the river is given by:
Where:
Ek is the kinetic energy
Ep is the potential energy
v is the speed of the river = 3 m/s
g is the gravity = 9.81 m/s²
h is the height = 58 m
Hence, the total mechanical energy of the river is 0.574 kJ/kg.
2. The power generation potential on the river is:
Therefore, the power generation potential of the entire river is 315.7 MW.

Volume % = mole %
Molar mass of oxygen = 32kg/kmol
Molar mass of nitrogen = 28 kg/kmol
Density of nitrogen = Density of
oxygen x molar mass of oxygen x molar ratio of air x molar mass of nitrogen
Density of nitrogen = (1.43kgm^-3)(1 kmol O2/32 kg O2)(80 kmol N2/ 20
kmol O2)(28 kg N2/1 kmol O2) = 5.01 kg/m3
Answer:
All of the above
Explanation:
all of the reactions use up energy to achieve the end product.
