Answer:
Q = 200800 Joules.
Explanation:
Given the following data;
Mass = 4kg
Initial temperature = 30.0°C
Final temperature = 90.0°C
Specific heat capacity of glass = 837 J/kg°C
To find the quantity of heat absorbed;
Heat capacity is given by the formula;
Where;
Q represents the heat capacity or quantity of heat.
m represents the mass of an object.
c represents the specific heat capacity of water.
dt represents the change in temperature.
dt = T2 - T1
dt = 90 - 30
dt = 60°C
Substituting the values into the equation, we have;
Q = 200800 Joules.
Therefore, the amount of heat absorbed is 200800 Joules.
Answer:
A dissipates more power.
Explanation:
- In a series circuit, the current is the same at any point in it.
- The power dissipated in any resistor follows Joule's law, as follows:
- So, for a given current, the power is directly proportional to the resistance of the resistor.
- In this case, as resistor A has twice the resistance of resistor B, A dissipates twice more power than B.
