R=U/I so
U=RxI
U= 10 x 42
U= 420 volts
Boyles law describes pressure volume relationship at constant temperature pressure is directly proportional to volume at constant tamparature
Answer:
Explanation:
Given
mass of lead piece
mass of water in calorimeter
Initial temperature of water
Initial temperature of lead piece
we know heat capacity of lead and water are and respectively
Let us take be the final temperature of the system
Conserving energy
heat lost by lead=heat gained by water
Answer:
