Answer:
Because it will allow a bigger temperature change.
Explanation:
The specific heat of the metal can be calculated by the heat change between it and the water. The total amount of heat must be 0, thus, the heat of the metal (Qm) plus the heat of water (Qw):
Qm + Qw = 0
The heat is the mass multiplied by the specific heat (c) and by the temperature change:
mm*cm*ΔTm + mw*cw*ΔTw = 0
mm*cm*ΔTm = - mw*cw*ΔTw
So, as higher is the value of mw, as low is the value of ΔTw, and if ΔTw is very low, and so the calculations may not be precise.
The answer is (D). The magnetic field is directly proportional to the number of coils. This is because, as you can see, as the number of coils goes up, the number of paper clips increases.
Answer:
This is math?

Answer:
The energy produced equals 140.760 kJ
Explanation:
The relation between power, current and voltage is
Applying the given values in the relation above we get
Now Since 
Again applying the calculated values we get
