Answer:
Explanation:
the sphere is solid and conducting, so the charge is uniformly distributed over its volume.
The answer is B (The second one). I'm not sure though.
Answer:
|x| = √53
Explanation:
We are told that the vector starts at the point (0.0) and ends at (2,-7) .
Thus, magnitude of displacement is;
|x| = √(((-7) - 0)² + (2 - 0)²)
|x| = √(49 + 4)
|x| = √53
300/8 = 37.5
37.5 x 12 = 450
New temp. = 450 K
Hope this helps!
