12km = 12000m
12000m / 4 m/s = 3000s
just under one hour
Human building a drainage system could affect the water cycle because :
C. water would be directed to a new location because of the drains
This could potentially changed the natural occurrence that usually happened within the water cycle
hope this helps
Answer: 40 N
Explanation: Use the formula
F = m a
to solve this.
F = (8 kg) (5 m/s²)
F = 40 kgm/s²
F = 40 N
Answer:
Z = 138.5 Ω
Explanation:
In a series RLC circuit the impedance is
Z =
the capacitive impedance is
X_C = 1 / wC
the inductive impedance is
X_L = wL
in this exercise indicate that C = 50 10⁻³ F, L = 0.3 H and the frequency is f=60 Hz
angular velocity and frequency are related
w = 2π f
w = 2π 60
w = 376.99 rad / s
let's calculate
Z =
Z =
Z = √19179.6
Z = 138.5 Ω
Answer:
the average speed of the car during this time interval is 40 m/s i thinkk..
