Answer:
19.2 m/s
Explanation:
The train is moving at 18 m/s and you are walking in the same direction (east) so the speeds are added
18 + 1.2 = 19.2
If you were walking backwards (west) your velocity with respect to the ground would be
18 - 1.2 = 16.8
Answer:
Stronger and harder than either of the pure metals
Explanation:
Answer:
B
Explanation:
A body has kinetic energy that is moving
Answer: Top left to bottom right, top right to bottom left
Explanation:
A linear position time graph means a horizontal line on the velocity graph so top left matches the bottom right
With the process of elimination, bottom left matches the top right
construction interference is when you build things up and destructive interference is when you tear things down
