Answer:
Explanation:
Let the velocity be Va for outbound journey and 1.2 Va for return journey .
Total time taken = 2400 / Va + 2400 / 1.2 Va
2400 / Va + 2400 / 1.2 Va = 20 / 3 h
1 / Va ( 2400 + 2000 ) = 20 / 3
4400 / Va = 20/3
Va = 4400 x 3 / 20 = 660 mi / h
A sprain is a stretch and/or tear of a ligament. It would cause pain but wouldn't actually dislocate anything. It's not the most painful injury, it can be healed, and stretching would help but not completely avoid a sprain. So that's why D is the answer.
Answer:
The vector magnitudes F and r are always postive, so the sign o W is determined entirely by the angle e between the force and the displacement.Submit Figure 1 off 1 part C
Using the equation: Q = mL
Q = 1(100) Q = 100cal
I hope this is right and helps :)
