Answer:
<u>Option-(D):</u>Thermal energy unchanged, temperature decreased.
Explanation:
<u>Thermal energy and Temperature,T:</u>
Thermal energy of the system is remained unchanged while the temperature,T of the objects present inside the system is more associated with the objects fundamental properties which each matter shows or exhibits in nature.
While the thermal energy is the flow or exchange of thermal or heat energy between the different objects in interaction to each other.
The particles that carry charge through wires in a circuit are mobile electrons. The electric field direction within a circuit is by definition the direction that positive test charges are pushed. Thus, these negatively charged electrons move in the direction opposite the electric field.
Answer:
Power, P = 30 W
Explanation:
We have,
Voltage drop of a circuit is 60 V
Resistance of the resistor is 120 ohms
Current across the circuit is 0.5 A
It is required to find the power conducted by the resistor. Power conducted by a resistor is given by :

V and I are voltage and current

So, the power conducted by the resistor is 30 watts.
