How do you find launch velocity only with time and distance
Annette [7]
To find initial velocity, start by multiplying the acceleration by the time. Then, divide that number by 2 and write down the quotient you get. Next, divide the distance by the time and write down that quotient as well. Finally, subtract your first quotient from your second quotient to find the initial velocity.

a 250 mH coil of negligible resistance is connected to an AC circuit in which as effective current of 5 mA is flowing. if the fr
mash [69]

Answer:

the inductive reactance of the coil is 1335.35 Ω

Explanation:

Given;

inductance of the coil, L = 250 mH = 0.25 H

effective current through the coil, I = 5 mA

frequency of the coil, f = 850 Hz

The inductive reactance of the coil is calculated as;

X_l = \omega L = 2\pi f L\\\\X_l = 2\pi \times 850 \times 0.25\\\\X_l = 1335.35 \ ohms

Therefore, the inductive reactance of the coil is 1335.35 Ω
