Answer: 8400 J
Explanation:
The formula referenced in the question is:
Where:
is the thermal energy
is the mass of the water sample
is the specific heat capacity of water
is the variation in temperature
Solving:
This is the thermal energy released
Explanation:
Substances with their density less than that of water which is 1 g/cm³ will float on it whiles those greater than that of water will sink into the water
From the question the density of the object is greater than that of water so the object will sink into the water
Hope this helps you
Answer:
Generation ----transmission---distribution
Explanation:
Electricity is generated from the generating station which could be (thermal, hydro, nuclear, coal etc) ,it is generated at a low voltage and is being step up to a higher voltage with the aid of transformers. This transformers step up and step down voltages from one level to another. At the transmission end they ensure the voltage get to the distribution end .the distribution end ensures the voltages are being supplied to nearby homes. The rated voltage for homes is 230v in some countries or 110V in other countries.
Electricity is useful and powerful for modern society because majority of the equipments in use today depends on electricity for use.which makes it very important.
