Answer:
Final Temperature of the steam tank = 456.4°C
Explanation:
Assuming it to be a uniform flow process, kinetic and potential energy to be zero, and work done and heat input to be zero also. We can conclude that,
Enthalpy of the steam in pipe = Internal Energy of the steam in tank
Using the Property tables and Charts - Steam tables,
At Pressure= 1 MPa and Temperature= 300°C,
Enthalpy = 3051.2 kJ/kg
At Pressure= 1 MPa and Internal Energy= 3051.2 kJ/kg,
Temperature = 456.4°C.
Answer:
B) an electron to move from ground state to an excited state.
Explanation:
Chlorophyll is a pigment that absorbs electromagnetic radiation of the visible spectrum that is used in process of photosynthesis. Chlorophyll's function is to absorb electromagnetic radiation of the visible spectrum and it absorbs blue color radiation the best and green the worst as it reflects it. It absorbs electromagnetic radiation by absorbing the energy of the photon of light by a process called charge separation.
Charge separation is the process by which an electron gets to a higher energy state by absorbing the energy of a photon.
Answer:
9.01amp
Explanation:
Power = V^2/R
Given that v = 11volts, P = 99watts
99 = 11^2/R
11×11 = 99R
121= 99R
R = 121/99
R= 1.22ohms
From ohms Law; V = IR
11volts = I × 1.22ohms
I = 11/1.23
I = 9.01 amp
Pitch is related to frequency
