Answer:
a) three times greater
Explanation:
Remember the heat capacity is the necessary heat to increase the temperature 1 ºC to an specific mass of the substance, in this case since the water and the metal have the same mass, is easier to compare just the neccesary heat.
Since water increases 20 ºC and the metal 60 ºC, it was neccesary 3 times of the quantity of heat to the same amount of mass of the two different susbtances.

Answer:
(a) 95 volt
(b) 134.33 volt
(c) 10.746 volt
(d) Average delivered power is 722 watt
Explanation:
We have given value of resistance R = 12.5 ohm
Current in the ammeter i = 7.60 A
(a) Rms voltage in the resistor 
(b) We know that rms voltage is given by 
So peak voltage will be equal to 134.33 volt
(c) Maximum current is equal to 
(d) Average power delivered in the resistor is equal to
P = VI
So 
Geocentric:
-The model is Earth centered
-Retrograde motion is explained by epicycles.
Heliocentric:
-This model is Sun-centered.
-Retrograde motion is explained by the orbital speeds of planets.
Both geocentric and heliocentric:
-Epicycles and deferents help explain planetary motion.
-Planets move in circular orbits and with uniform motion.
-The brightness of a planet increases when the planet is closest to Earth.
