Answer : The heat created by the food is, 3971 J
Explanation :
Formula used:

where,
q = heat produced = ?
m = mass of water = 100 g
c = specific heat capacity of water = 
= change in temperature = 
Now put all the given values in the above formula, we get:


Therefore, the heat created by the food is, 3971 J
The resistance of the appliance is 64.1 Ω.
<u>Explanation:</u>
As per the Ohm's law, which states that the electric current is in direct proportion to the voltage and is in inverse proportion to the resistance. It is given by the expression as,
V = IR
Where V is the voltage (V) = 150.0 V
I is the current (amps) = 2.34 amps
R is the resistance (ohm) or Ω = ?
Now we have to rearrange the equation to get the resistance as,

Now we have to plug in the values as,

= 64.1 Ω
So the resistance of the appliance is 64.1 Ω.
Bc in the old times there were no phone and social media like now so that’s why it changed a lot the technology
