<span>A material through which a current does not move easily is called
an insulator.
Technically, charges CAN move through an insulator, but they lose
a lot of energy doing it, so the current that flows through the insulator
is very very small, usually too small to even measure.
Another way to look at it: Insulators have high resistance.

Compute the components of the given vectors. Let
denote the plane's velocity vector, and
the wind. Then



The resultant velocity (rounded) is

with magnitude
and direction
, or about 258 mi/hr at 47.7 degrees south of east.
Answer:Zero
Explanation:
Given
mass of ball 
If the ball is thrown upward then at maximum point velocity of ball is zero because ball is no longer able to move upward
Momentum(P) of a particle is given by



Therefore at the highest point momentum is zero .
