12.) 15 : 10 Times Each One By 0.3
15*0.3= 4.5
15-4.5 = 10.5
10*0.3= 3
10-3=7
The Scale Factor Is 10.5:7
Answer:
Option B is true: The system can do no work
Explanation:
a. The system releases energy at a steady rate. False
In thermodynamic equilibrium there are no net macroscopic flows of matter or of energy, either within a system or between systems.
b. The system can do no work. True
If the connection between the systems allows transfer of energy as heat but does not allow transfer of matter or transfer of energy as work, the two systems may reach thermal equilibrium without reaching thermodynamic equilibrium.
c. The system consumes energy at a steady rate. False.
In thermodynamic equilibrium there are no net macroscopic flows of matter or of energy, either within a system or between systems.
d. The kinetic energy of the system is zero. False.
At maximum displacement from the equilibrium point, potential energy is a maximum while kinetic energy is zero. At the equilibrium point the potential energy is zero and the kinetic energy is a maximum. At other points in the motion the oscillating body has differing values of both kinetic and potential energy.
Answer:
The answer is option 2 : NO3
An enzyme can affect a chemical reaction by bringing the reactant closer together - chemical bonds may be weakened, and reactions will happen faster than without a catalyst. The energy can also be lowered, which means reactions will proceed at a lower temperature, light presence, etc.
