An electric water heater is delivering hot water at 50 C. The cold water enters the water heater at 10 C. The volume of the water heater is 160L and one fourth of the tank volume is cold water when the 5 kW electric heating element turns on. Once the heating element turns on, the internal energy of the water tank is a. Increasingb. Decreasingc. Constant

Abaseball has a mass of 0.145 kg and approaches a bat at 40.0 m/s. after it is hit, the ball leaves the bat at 50.0 m/s directly back. find the impulse of the bat on the ball. 7.25 kg*m/s 13.1 kg*m/s 5.80 kg*m/s 1.45 kg*m/s

There are weak or strong attractive forces between atoms of liquids with a high viscosity

10 points! will mark brainiest! in a heat engine if 1,000 j of heat enters the system and the piston does 500 j of work, what is the final internal energy of the system if the initial energy was 2,000 j 1: write the equation 2: list out your known variables 3: plug the numbers into the equations 4: solve 5: write your solution statement that includes initial energy and final energy added you so much!
