Answer:
B. 8.0m/s
Explanation:
Distance between waves = 50m
T = 6.25secs
Speed = 50m/6.25secs
= 8.0m/s
Answer:
it would have to be 1 or maybe 2
Answer:
124.86 V
Explanation:
We have to first calculate the voltage drop across the copper wire. The copper wire has a length of 358 ft
1 ft = 0.3048 m
358 ft = 109.12 m
The diameter of 2 AWG copper wire (d) = 6.544 mm = 0.006544 m
The area of the wire = πd²/4 = (π × 6.544²)/4 = 33.6 mm²
Resistivity of wire (ρ) = 0.0171 Ω.mm²/m
The resistance of the wire =
The voltage drop across wire = current * resistance = 6.1 A * 0.056 ohm = 0.34 V
The voltage at end = 125.2 - 0.34 = 124.86 V
Answer:
Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement.
