Answer: The coefficient of friction is 0.35

Explanation:

We can write the friction force as:

F = N*μ

Where N is the normal force between the refrigerator and the ground, as the full weight of the refrigerator is acting on the ground, the normal force will be exactly equal to the weight of the refrigerator, then:

N = 650N

And μ is the coefficient of friction.

And for this case, the force is 230N, then we have:

F = N*μ

230N = 650N*μ

(230N/650N) = μ = 0.35

Notice that the distance did not matter for this calculation.

serious [3.7K]

Answer:

Incomplete question: "A signal of 20.7 mV is measured at a distance of 29 mm and 15.8 mV is measured at 32.5 mm. Correct the data for background and normalize the data to the maximum value. What is the normalized corrected value at 32.5 mm?"

The normalized corrected value at 32.5 mm is 0.1638

Explanation:

The corrected light measurement at 29 mm is equal to:

20.7 - 5.1 = 15.6 mV

The corrected light measurement at 32.5 mm is equal to:

15.6 - 5.1 = 10.5 mV

To normalize the data to its maximum value means that the maximum value must be calculated and the data must be scaled using that value, as in this case the maximum value is 15.6 mm, then the normalized corrected value at 32.5 mm is equal to:

10.5 * 15.6 = 163.8 = 0.1638

frutty [35]

Answer:

<u>-1.35 N</u>

Explanation:

<u>Force due to q1</u>

  • F = 9 × 10⁹ × 5 × 10⁻⁶ × 2.5 × 10⁻⁶ / 0.5²
  • F = 450 × 10⁻³
  • <u>F = 0.45 N (+)</u>

<u>Force due to q2</u>

  • F = 9 × 10⁹ × 5 × 10⁻⁶ × 2.5 × 10⁻⁶ / 0.25²
  • F = 1800 × 10⁻³
  • <u>F = 1.8 N (-)</u>

<u />

<u>Net Force</u>

  • 0.45 - 1.8
  • -1.35 N
