Answer: The current must be equal to amps, or ~0.9574 amps.
Explanation:
You can find the current in amperes using ohms and watts from this formula:
Where P represents power in watts, R represents resistance in ohms, and I represents current in amperes.
You can then substitute 60 and 55 into the equation to find I:
Then, simplify the denominator:
Rationalize the denominator:
Simplify the numerator by finding its factors:
The current must be equal to amps, or ~0.9574 amps.
Answer:
819.78 m
Explanation:
<u>Given:</u>
- OA = range of initial position of the airplane from the point of observation = 375 m
- OB = range of the final position of the airplane from the point of observation = 797 m
= angle of the initial position vector from the observation point =
= angle of the final position vector from the observation point =
= displacement vector from initial position to the final position
A diagram has been attached with the solution in order to clearly show the position of the plane.
Displacement vector of the airplane will be the shortest line joining the initial position of the airplane to the final position of the airplane which is given by:
The magnitude of the displacement vector =
Hence, the magnitude of the displacement of the plane is 819.67 m during the period of observation.
