Answer:
first what is the question
The distance of the object from the mirror is 3cm.
To calculate the distance of the object from the mirror, we make use of the mirror formula
<h3>Mirror formula</h3>
- 1/f = (1/u)+(1/v)............ Equation 1
Where:
- f = Focal length of the mirror
- v = image distance
- u = object distance.
Using the real is positive convention,
Given:
Substitute these values into equation 1 and solve for u
- 1/5 = (-1/10)+(1/u)
- 1/5+(1/10) = 1/u
- 1/u = (2+1)/10
- 1/u = 3/10
- u = 10/3
- u = 3.33
- u = 3 cm
Hence, The distance of the object from the mirror is 3cm.

Answer:
30
We'll be using the 5 numbers in your question.
In order to solve this problem, we need to know what range is.
The range is the spread of your data from the <u>lowest</u> to the <u>highest</u> value.
In order to find the range, we need to order the values from least to greatest.
Note: No picture of the stem-and-leaf plot is given in the question.
From least to greatest:
2, 5, 14, 19, 32.
Next, find the maximum and the minimum values.
Minimum: 2
Maximum: 32
Lastly, subtract the maximum and the minimum:
32-2=30.
Your range is 30.
For a cell reaction to be sponteanous, the standard cell potential must be positive.
<h3>What is a sponteanous cell reaction?</h3>
We define a cell reaction as sponteanous when the value of the standard cell potential is positive. If the standard cell potential is negative then the reaction is not sponteanous.
The question here is incompete but we know that the reactions that are sponteanous will all have a positive standard cell potential.
