Answer:
Explanation:
400 W = 400 J/s
300000 J / 400 J/s = 750 s or 12.5 minutes
Answer:
it bc the adults are bigger then us kid so when they dip in the pool it makes bigger splashes
Explanation:
The answer is as voltage increases current increases and therefore resistance would remain constant
The heat capacity and the specific heat
R = ρ L/A. R= resistance, ρ= resistivity, L= length of the conductor. A = area of the conductor. Resistance is directly proportional to the length of the conductor. So if length of the conductor is decreased, resistance will also decrease. Hence A is the correct option
