The resultant force is 4 N to the right.
Answer:
<em>Rt = 8 ohm</em>
<em>I = 2 A</em>
<em>Vab = 12 V</em>
<em>VbΓ = 4 V</em>
<em>VaΓ = 16 V</em>
Explanation:
<u>Electric Circuits</u>
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:


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
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
As per question the initial states of the gases are given as
INITIAL STATE: FINAL STATE:
![v_{2} =3v[say]](https://tex.z-dn.net/?f=v_%7B2%7D%20%3D3v%5Bsay%5D)

AS per combined gas equation obtained from the combination of Boyle's law and Charles law [Basic ideal gas laws]

Hence
