D. Destructive interference. An easy way to think about it is the waves are opposite each other, so they essentially cancel each other out, or make an effort to.
Answer:
You could say that it was not a chemicly change because that is when you say this is just a example that if you cook eggs you cant un-cook them
Explanation:
Answer:
a. 240 N due east
b. 540 N due west
Explanation:
Let east be the reference direction
(a) if the resultant force has a magnitude of 390 N and points east, and the 1st force is 150N due East, then the additional force would also due east and has a magnitude of
390 - 150 = 240 N
(b) if the resultant force has a magnitude of 390 N and points west, it would be -390N is eastern reference, and the 1st force is 150N due East, then the additional force would also due east and has a magnitude of
-390 - 150 = -540 N
This force would point west
Answer:
D). Last option is the correct choice.
Explanation:
Thanks!
Answer:
Force = 533.33N
Explanation:
Given the following data;
Power = 40000watt
Velocity = 75m/s
To find the force;
Making force the subject of formula, we have;
Force = 533.33N
