A planet orbiting a star in a eclipse and sometimes it is closer to the star but sometimes it is farther. When it is closer the gravity on the planet from the star is stronger and it speeds up. The area the planet sweeps over is equal because when it speeds up the length covered along the orbital path is greater, but it is also closer to the star, and that dimension is decreased.
Answer:
A.REARRANGED AND FORM NEW SUBSTANCES WITH NEW PROPERTIES
Explanation:
Before the fuel is burned, it's chock full of chemical energy. When the fuel is burned, the chemical energy is released, and it escapes in the form of heat and light energy.
Answer:
So if its acceleration is -2m/s^2 that means every second the initial velocity would be subtracted by 2. So since it took 3 seconds 2*3=6. The initial velocity was 6 m/s
