Answer:

V=IR

since the circuit is parallel both resistor have same voltage and different current value according to OHMs law.

total resistance in parallel=

1/R=1/R1+1/R2+...+1/Rn

since we have two resistor in parallel

Rt=R1R2/R1+R2

2*4/2+4=4/3 ohms

I=V/R

12/4/3=36/4=9Amp

OR

I=12/2=6amp

I=12/4=3amp

total current

I=6+3

9amp

anygoal [31]

To find the Voltage, ( V ) [ V = I x R ] V (volts) = I (amps) x R (Ω)

To find the Current, ( I ) [ I = V ÷ R ] I (amps) = V (volts) ÷ R (Ω)

To find the Resistance, ( R ) [ R = V ÷ I ] R (Ω) = V (volts) ÷ I (amps)

To find the Power (P) [ P = V x I ] P (watts) = V (volts) x I (amps)

Which of these would represent the force of gravity
tigry1 [53]

Missing figure: find it in attachment.

Answer:

Force D

Explanation:

In order to answer the question, let's keep in mind that the force of gravity on an object on Earth is the attractive force exerted by the Earth on the object; its direction is always downward (towards the Earth's centre), and its magnitude is given by

F = mg

where m is the mass of the object and g is the acceleration of gravity.

It follows immediately that in the figure, the force of gravity is the only force acting downward: therefore, force D.

The other forces are called:

Force A: thrust (it is the forward force generated by the engines)

Force B: lift (it is the upward produced by the aerodynamics of the wings)

Force C: air resistance (it is the backward force due to the friction between the air and the surface of the plane)
