Rudiy27

Answer:

Lens at a distance = 7.5 cm

Lens at a distance = 6.86 cm  (Approx)

Explanation:

Given:

Object distance u = 12 cm

a) Focal length = 20 cm

b) Focal length = 16 cm

Computation:

a. 1/v = 1/u + 1/f

1/v = 1/20 + 1/12

v = 7.5 cm

Lens at a distance = 7.5 cm

b.  1/v = 1/u + 1/f

1/v = 1/16 + 1/12

v = 6.86 cm  (Approx)

Lens at a distance = 6.86 cm  (Approx)

A scale measures the weight of a light object to be 11.000 lbs ± 0.034 lbs. what is the uncertainty if this same scale is use to
Gre4nikov [31]

The uncertainty of the heavy object if the scale remains constant is 0.24 lbs.

<h3>What is uncertainty in measurement?</h3>
  • This is the error associated in an attempt measure the object accurately.

The percent uncertainty in measuring the light weight object is calculated as follows;

= \frac{0.034}{11} \times 100\%\\\\= 0.309\%

The uncertainty of the heavy object if the scale remains constant is calculated as follows;

= \frac{0.309}{100} \times 78.0 \ lbs\\\\= 0.24 \ lbs
