Answer:
12.75 A
Explanation:
The total power is 300 + 30 + 960 + 2 × 120 = 1530 W
Electrical power is given by
Then
With a voltage of 120 V,
A = distance traveled by steve in north direction by train = 30 miles
B = distance traveled by steve in east direction by train = 25 miles
R = resultant displacement of the steve relative to starting position
using pythagorean theorem
R = √(A² + B²)
inserting the values
R = √(30² + 25²)
R = 39.05 miles
direction : tan⁻¹(B/A) = tan⁻¹(25/30) = 39.8 deg east of north
