Answer:
The rescue crew should fly to go directly to the field to 164.73 mi at 18.99° south of east.
Explanation:
To know the total distance, we need to use cartesian coordinates. The distance that should fly the rescue crew to the east is the decomposition of both travels on this direction, it is the same way to the travels on the another axle. So and when we have got result of both travels, we use the trigonometric identity know Arctan; to find the direction. Then we need to use the pythagorean theorem to get the distance that the rescue crew should travel; . Ordering the data we get distance 164.73 mi at 18.99° south of east.
Answer:
-2.67 m/s²
Explanation:
a = Δv / Δt
a = (14 m/s − 30 m/s) / (6 s − 0 s)
a = -2.67 m/s²
Answer:
Explanation:
length of the wire = L
Potential difference = Vo
Current = I
new length of the wire, L' = L/2
As we know that the resistance of the wire is directly proportional to the length of the wire.
As the length is halved so that the resistance is also halved.
Resistance = Voltage / Current
V = I R
So, Voltage is constant and the resistance is halved so that the current is doubled.
Answer:
THE LAW OR PRINCIPLE OF SUPERPOSITION; States that when two identical waves are brought, the resultant disturbance is the algebraic sum of the individual disturbances of the two waves.
Explanation:
Most stationary waves are obtained as a result of the combination or superposition of an incident wave and it's reflected wave. Like in music, they result from the stationary waves of plucked strings leading to the Superposition law.
