If R1 = 6, R2 = 2 and VAΓ = 16 Find Roλ, I, VAB, VAΓ

erica [24]

Answer:

Rt = 8 ohm

I = 2 A

Vab = 12 V

VbΓ = 4 V

VaΓ = 16 V

Explanation:

Electric Circuits

We'll apply Ohm's formula to solve the circuit shown on the image:

V = R.I

Where V is the voltage, R is the resistance, and I is the current.

The circuit has two resistances connected in series, thus the total resistance is:

Rt = R1 + R2 = 6 ohm + 2 ohm = 8 ohm

Now the current is:

$\displaystyle I=\frac{V}{Rt}$

$\displaystyle I=\frac{16}{8}$

I = 2 A

The voltages are calculated below:

Vab = R1 * I = 6 ohm * 2 A = 12 V

VbΓ = R2 * I = 2 ohm * 2 A = 4 V

VaΓ = Vab + VbΓ = 12 V + 4 V = 16 V

How does kinetic energy affect the stopping distance of a vehicle traveling at 30 mph compared to the same vehicle traveling at

slavikrds [6]

So the answers to your questions are the following:
#2 The Kinetic Energy is equals to the work done to stop.
#3 The mass is directly proportional to the stopping distance of the car.
#4 Speed should be decrease in order the car to prepare on the sharp curves.
#5 It depends to the speed and acceleration of the car and also its inertia which would be affected by the sudden stop of the vehicles
