Presume we are looking for the current:

V = IR

120 = I*360

120/360 = I

1/3 = I

I = 1/3 = 0.333..

Current ≈ 0.33 Ampere.

Answer:

i = 0.33 A

Explanation:

As per ohm's law we know that voltage across any ohmic resistor is product of resistance and current through it

So it is given as

V = i R

now we know that

V = 120 Volts

R = 360 ohm

so here we have

120 = 360 \times i

i = \frac{1}{3} A

A car is moving at 14 m/s. After 30 s, its speed inncreased to 20 m/s. What is the acceleration over time
Juli2301 [7.4K]

Answer:

0.2 m/s^2

Explanation:

initial speed 14m/s

final speed 20m/s

acceleration:

(20m/s - 14m /s) /30s = (6m/s)/30s = 0.2 m/s^2
