Power = (work done) / (time to do the work)
Power = (energy moved) / (time to move the energy)
Power = (voltage) x (current)
Power = (voltage)² / (resistance)
Power = (current)² x (resistance)
<span>The answer is 6 Joules. The kinetic energy (KE) of an object is the product of half of the mass (m) of the object and the square of its velocity (v²): KE = 1/2m*v². We know that m = 0.75 kg and that v = 4 m/s. Therefore, KE = 1/2 * 0.75 kg * (4 m/s)² = 1/2 * 0.75 kg * 16 m²/s² = 6 kg*m²/s² = 6 J.</span>
The answer is A. As a stable configuration is reached when atoms bond, so you are in a state of lower energy than not bonded.
The water molecules expand. When anything heats up, molecules spread further apart.
