What is the total current I flowing through a system with two resistors in parallel with resistances of 2Ω and 5Ω, and a battery
Andrej [43]

Answer:

7A

Explanation:

Current I = potential difference V ÷ Resistance R

I = V/R ........1

The overall resistance of parallel resistors is;

1/Rt = 1/R1 + 1/R2 ........2

Given;

V = 10V

R1 = 2 ohms

R2 = 5 ohms

Substituting the values into equation 2, to calculate the overall resistance;

1/Rt = 1/2 + 1/5

1/Rt = 7/10

Rt = 10/7 ohms

From equation 1, we can solve for the total current;

I = V/Rt = 10/(10/7)

I = 7A

The total current I flowing through a system is 7A

During take-off a 8kg model rocket is burning fuel causing its speed to increase
77julia77 [94]

The strength of the thrust is 122 newtons.

The motion of the rocket is described by the second Newton's law, whose model is shown below:

\Sigma F = F - D = m\cdot a (1)

Where:

  • F - Thrust, in newtons
  • D - Drag, in newtons
  • m - Mass of the rocket, in kilograms
  • a - Net acceleration of the rocket, in meters per square second

If we know that D = 90\,N, m = 8\,kg and a = 4\,\frac{m}{s^{2}}, then the strength of the thrust is:

F = D + m\cdot a

F = 90\,N + (8\,kg)\cdot \left(4\,\frac{m}{s^{2}} \right)

F = 122\,N

The strength of the thrust is 122 newtons.
