Answer : The correct option is, (C) cannot be reversed
Explanation :
The thermodynamic process is a process in which the thermal or heat energy is converted into mechanical energy and some amount of energy goes into surroundings. That means, the total amount of energy is not converted into mechanical energy.
Or we can say that the energy can not be created or destroyed, it can only change or transfer from one state to another state.
The thermodynamic process is not a reversible process that means it is an irreversible process.
Hence, the correct option is, (C) cannot be reversed
1. V= 110
I= 11
R=10
2. V= 110
I= 5.5
R= 20
3. V= 100
I= 5
R= 20
4. V= 500
I= 5
R= 100
To show work plug in those numbers to V=IR
Explanation:
Surface runoff: Excessive water collected on the land due to rains, storms, water melts and from other sources flows over the earth surface.
Transpiration: Moisture in the plants are absorbed by the roots and distributed in all the parts of plant. Moisture present in the underside of the leaves get converted into water vapors and releases in atmosphere
Evaporation : In this process , liquid state of water is converted into gaseous state of water that is water vapors.
Condensation: After evaporation , the water vapors rises up towards the sky. As they rise in the atmosphere the temperature decrease due which these water vapors stars getting converted into small water droplets. These small water drops combines with particles of dust , gas to form clouds
Precipitation: Water released from the clouds in the form of rain.
Answer:
-833.3 N/C
Explanation:
Kinetic energy, K, in terms of electric field, E, is given as:
K = qEr
q = charge = e = 1.6 × 10⁻¹⁹C
E = Electric field
r = distance = 0.3m
The electric field can be gotten by making E subject of formula:
E = K/(qr)
The electeic field needed to stop the electrons must be equal in magnitude to the electric field carried by these electrons:
E = (4.0 × 10⁻¹⁷)/(-1.6 × 10⁻¹⁹ * 0.3)
E = -833.3 N/C
This is the electric field needed to stop the electrons.
The negative sign means that the electric field must be in a direction opposite to the motion of the electrons.
