How much energy is used by a 900 w microwave that operates for 4 minutes ?
a 260,000 j
b 215,000 j
c 3600 j
d 225 j

Which of the following bonds would be most polar? a. c-i b. c-br c. c-cl d. c-f e. c-o

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!

An owl dives toward the ground with a constant velocity of 4.40 m/s at 53.0° below the horizontal. the sun is directly overhead and casts a shadow of the owl directly below it. what is the speed (in m/s) of its shadow on level ground?
