How many grams of ice at -14°C are needed to cool 200 g of water from 25°C to 10°C. (Take specific heat of ice =0.5 cal g^-1 °C^-1 and latent heat of ice = 80 cal g^-1)

Rohit is trying to tune an instrument

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!

The pilot of a helicopter hovers at an altitude of 1200 feet over a park. the angle of depression to the base of a statue is 17 degrees. the angle of depression to the nearest park exit, in line with the statue, is 14 degrees. to the nearest foot, what is the distance from the statue to the exit?
