Answer;
- Line segment
Explanation;
"from earth to moon" implies endpoints at both locations and it is thus a line segment
A line extends forever in both directions, a line segment is just part of a line. It has two endpoints, and a ray starts at one point and continues on forever in one direction.
Taking the vertical component of the displacement
1.1 - 0.2 = 0.9 mile
The horizontal component of the displacement
-0.3 mile
The magnitude of the displacement is
√[ (0.9)² + (-0.3) ] = 0.95 mile
The direction is
θ = tan-1 (-0.3/0.9)
θ = 161.57 degrees.
When you turn on a battery-operated device, an electrical circuit is closed.
Explanation:
A circuit works, only when it is closed. When we turn on the battery-operated device, the circuit is closed & complete. Hence, the current will flow across the circuit.
Only closed circuits work (current flows through them). No current can flow in an open circuit.
