Answer:
65 meters to the right.
Explanation:
the shark moves to the right 30 meters and then to the left 15 making his new placement 15. he then moved to the right 50 meters making his new placement 65 meters to the right.
C) Y is the strongest point in the electric field.
Well it would tell us the number of neutrons and protons in the nucleus so i would assume the number of energy levels.
Explanation:
We have,
Mass of a car is 1285.0 kg
Initial speed of a car is 25 m/s in an easterly direction
Mass of a truck is 600 kg
Initial speed of a truck is 20 m/s
After the collision, final velocity of the car is 18 m/s
(A) Let is the velocity of velocity of the truck right after the collision. Using conservation of linear momentum. So,
(B) Initial kinetic energy of truck car system :
(C) Final kinetic energy of truck car system :
So, the change in kinetic energy is :
(C) The change in mechanical energy occurs when the energy gets converted in the form of heat and sound energy.
