Two point charges are fixed on the y axis: a negative point charge q1 = -34 μC at y1 = +0.18 m and a positive point charge q2 ar

t y2 = +0.33 m. A third point charge q = +8.1 μC is fixed at the origin. The net electrostatic force exerted on the charge q by the other two charges has a magnitude of 31 N and points in the +y direction. Determine the magnitude of q2.

Answer:

Explanation:

Field by negative charge will be more as net force due to both the charges is in positive y - direction.

field by negative charge at origin

= 9 x 10⁹ x 34 x 10⁻⁶ / .18²

= 9.45 x 10⁶ N /C

field by positive  charge at origin

= 9 x 10⁹ x Q / .33²

= 82644.63 x 10⁶ Q N /C

Net field

= 9.45 x 10⁶ - 82644.63 x 10⁶ Q

force on charge 8.1 x 10⁻⁶ C

( 9.45 x 10⁶ - 82644.63 x 10⁶ Q ) X 8.1 x 10⁻⁶  = 31

76.545 - 669421.5 Q = 31

669421.5 Q = 45.545

Q = 45.545  / 669421.5

= 68 X 10⁻⁶ C

= 68 μC

Explain, step by step, how to calculate the amount of current (I) that will go through the resistor in this circuit
anygoal [31]

Answer:

0.03 A

Explanation:

From the question given above, the following data were obtained:

Voltage (V) = 12 V

Resistor (R) = 470 Ω

Current (I) =?

From ohm's law, the voltage, current and resistor are related by the following formula:

Voltage = current × resistor

V = IR

With the above formula, we can obtain the current in the circuit as follow:

Voltage (V) = 12 V

Resistor (R) = 470 Ω

Current (I) =?

V = IR

12 = I × 470

Divide both side by 470

I = 12 / 470

I = 0.03 A

Thus, the current in the circuit is 0.03 A

Choose what colors are absorbed when white light hits a red apple. (Pick all that apply.)
astra-53 [7]
A red apple absorbs all colors of visible light except red, so red light
is the only light left to bounce off of the apple toward our eyes. 
(This is a big part of the reason that we call it a "red" apple.)

Here's how the various items on the list make out when they hit the apple:
