The resistance expected of the heater is 50.1 ohms.
<h3>What is resistance?</h3>
Resistance can be defined as the opposition to the flow of electric current in an electric circuit. The S.I unit of resistance is Ohms (Ω).
To calculate the resistance of the heater, we use the formula below.
<h3>Formula:</h3>
- R = V²/P............. Equation 1
Where:
- R = Resistance of the heater
- P = Power of the heater
- V = Voltage supplied to the heater
From the question,
Given:
- V = 480 V
- P = 4.6 kW = 4600 W
Substitute these values into equation 1
- R = (480²)/4600
- R = 50.1 ohms.
Hence, the resistance expected of the heater is 50.1 ohms.

Yaaaas, do you watch James Charles!?
Answer:
ozone, letter b
ozone is basically an allotrope of oxygen having three atoms instead of two.
The given question is incomplete. The complete question is as follows.
A picture window has dimensions of 1.40 m, 2.50 m and is made of glass 6.00 mm thick. On a winter day, the outside temperature is
, while the inside temperature is a comfortable
.
Part A
At what rate is heat being lost through the window by conduction?
Express your answer using three significant figures.
Part B
At what rate would heat be lost through the window if you covered it with a 0.750 mm-thick layer of paper (thermal conductivity 0.0500 W/m?K)?
Express your answer using three significant figures.
Explanation:
Formula for rate of heat transferred through single thick plane of glass is as follows.

= 
= 
When window is covered by paper then the rate of heat transfer is as follows.

= 
= 
Thus, we can conclude that heat lost is
.
