Answer:
400 V
Explanation:
Electric filed , E=800 V/m
We know that
Using the formula
Hence, the potential at x=2 m=400 V
Answer:
Plug in the given values and solve for the final velocity. Remember, when the ball is on the ground it has a height of zero.
Explanation:
Answer:
sound travel fastest through solids this is because molecules in a solid media much closer together then throws in a liquid or gas flowing sound ways to travel more quickly throw it in fact sound waves travel over 17 times faster throw Steel then through air
To get the solution you must need to draw a force triangle. Attach the head of the 60N north force arrow with the tail of the 60N east force arrow. The subsequent is the arrow connecting he tail and head of the two arrows.
You get a right angled triangle, and the resultant is (60^2 + 60^2) ^0.5 = 84.85 N or 85 N northeast.
