Answer:
A conductor allows free charges to move about within it. The electrical forces around a conductor will cause free charges to move around inside the conductor until static equilibrium is reached. Any excess charge will collect along the surface of a conductor. Conductors with sharp corners or points will collect more charge at those points.
Explanation:
Answer:
1800 m/
Explanation:
We know this because of Newton's first law, 
, which shows us that the force on an object is equal to its mass times the acceleration it recieves. This means that taking our values of 900N and 0.5kg, and plugging them in,
This is honestly a little strange because the force applied and the acceleration seem ridiculous, and a little strange for an answer. Either the values are not meant to be nearly close to reality, or you made a typo.
The best statement would be number 3. Sound waves move perpendicular to the medium particles.
Answer:
use the formula for option B ( d/t = s )
and
look at the graph representation to explain
