Answer:
Kinetic energy = (1/2) (mass) (speed²)
First object: (1/2) (2 kg) (2 m/s)² = 4 joules .
Second object: (1/2) (4 kg) (3 m/s)² = 18 joules .
The second object had more kinetic energy than the first one had.
Explanation:
C dependent variable because dependent means relying on something else
(1.5 m^3) • (1.05 kg/m^3) = 1.575 kg. That's quite a bag you've got there ! 1 m^3 is like 264 gallons of blood. Hope the poor patient survives the transfusion.
Also, the actual density of blood is around 1.05 g/cm^3, or 1050 kg/m^3.
The blood they're giving the guy in this question is about 18% less dense than the AIR in his hospital room, and they're pumping 264 gallons of it into him. Maybe THAT'S his whole problem.
Electronic force related to magnitude by magnets. It is a magnetic force. So basically there is a big magnet in the center of earth. Keeps same energy. Right on edg
Time = distance/speed
Time = 8•10^14m / 3•10^8m/s
Time = about 2.7•10^6 seconds.
That's about 31 Earth days.
