A 230-volt, 3-phase, 25-horsepower, squirrel-cage motor and a 230-volt, 30-horsepower synchronous motor are installed on the same motor branch circuit. What is the minimum ampacity of the conductors for this single branch circuit?

The two stars in a certain binary star system move in circular orbits. the first star, alpha, has an orbital speed of 36 km/s. the second star, beta, has an orbital speed of 12 km/s. the orbital period is 137 d. a) what is the mass of the star alpha? b) what is the mass of the star beta?

Mechanical energy is when the amount of kinetic and potential energies added together remains the same. conserved created lost

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!
