Answer:

C. Plate A is negatively charged and plate B is positively charged.

Explanation:

The direction of the lines of an electric field represents the direction to which a positive test charge placed in that field would move. Therefore, since positive charges are repelled by positive charges and attracted by negative charges, this means that:

- Electric field lines point away from positive charges, and

- Electric field lines point towards negative charges

In the figure in the problem, we see that electric field lines go away from plate B and towards plate A. This means that:

- Plate B is positively charged

- Plate A is negatively charged

The closest star to our solar system is Alpha Centauri, which is 4.12 × 10^16 m away. How long would it take light from Alpha Ce

bonufazy [111]

Time = (distance) / (speed)

Time = (4.12x10^16 m) / (3 x10^8 m/s)

Time = 1.37 x 10^8 seconds

Divide the seconds by 86,400 to get days. Then divide the days by 365 to get years.

Time = about 4.35 years

A circuit contains a 12 volt battery and two 3 ohm bulbs in series. Calculate the current

OLEGan [10]

If there are two bulbs in series, and each bulb has

resistance = 3 ohms,

then their total resistance in series is 6 ohms.

When the series pair of bulbs is connected across the terminals
of the battery, the current through the circuit is

Current = (voltage) / (resistance)

= (12 volts) / (6 ohms) = 2 amperes

Svetllana [295]

<span>To get that, find the time when slope equals to 0, use the derivate theory from calculus.

s = 8 cos t + 9 sin t, t ≥ 0
s' = -8 sin t + 9 cos t (this is slope)
0 = -8 sin t + 9 cos t
8 sin t = 9 cos t
tan t = 9/8
t = 48.37 seconds</span>
