In a dorm, there are a few electric devices running at a voltage of 110 V. A refrigerator that runs with a current of 4.0 A, a heater with a resistor of 10 Ω at room temperature, a fan that exerts 12 Nm toque with a constant angular velocity of 8 rad/s. What is the total power? If the resistor in the heater has a temperature dependence with α = 0.01. When the heater reaches 500 ̊C, what is the change in total power in the dorm?

Question

Definition Definition Rate of change of angular displacement. Angular velocity indicates how fast an object is rotating. It is a vector quantity and has both magnitude and direction. The magnitude of angular velocity is represented by the length of the vector and the direction of angular velocity is represented by the right-hand thumb rule. It is generally represented by ω.

A physics student has a single-occupancy dorm room. The student has a small refrigerator that runs with a current 2 A, a lamp that contains a 100-W bulb, an overhead light with a 60-W bulb, and various other small devices adding up to 7 W. All the appliances run on a voltage of 110 V. Overall Hint a. What is the total power used by the dorm room (while the refrigerator runs)? Total power used by the dorm room is b. Assuming that the power plant for the electricity is 16 km away and uses 000-gauge copper wire (diameter 10.405 mm), how much power is dissipated in transmission (remember to count the return wire), if the power plant is directly providing the 110-V?
