Answer:
Explanation:
The specific heat of gold is 129 J/kgC
It's melting point is 1336 K
It's Heat of fusion is 63000 J/kg
Assuming that the mixture will be solid, the thermal energy to solidify the gold has to be less than that needed to raise the solid gold to the melting point. So,
The first is E1 = 63000 J/kg x 1.5 = 94500 J
the second is E2 = 129 J/kgC x 2 kg x (1336–1000)K = 86688 J
Therefore, all solid is not correct. You will have a mixture of solid and liquid.
For more detail, the difference between E1 and E2 is 7812 J, and that will melt
7812/63000 = 0.124 kg of the solid gold
The required voltage in a circuit for an electric dryer to be placed in a laundry area in a home is 240-V, three-wire circuit with equipment grounding.
An electric dryer is a home appliance for laundry activities that operates heating coils on a 240-volt current, three-wire circuit. They are better to use than the gas dryers and they have a low maintenance cost.
During usage, the internal drum revolves via the use of electricity while the electric fan circulates heated air to dry the clothes.
- The 120-V three-wire circuit with equipment grounding is required for use by the washing machine.
- Similarly, a washer requires a 20-A circuit but not a separate one as said in the question.
Therefore, we can conclude that the required voltage in a circuit for an electric dryer to be placed in a laundry area in a home is 240-V, three-wire circuit with equipment grounding.

.....When astronomers developed ways to measure distances, they could plot, this angle from north, this many light years, so relative to us that star is here. Plot many stars this way and you will see the shape of the galaxy.... i think this is a response right?
The answer is shape, waves keep the same shape when bouncing off something
