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.

As an object falls toward earth, the potential energy of the object: Decreases
<h3>What is the gravitational potential energy towards the earth?</h3>
In this case, the formula for the Potential energy is:
E = Em + Ek + Eg
Where;
Em is energy due to mass
Ek is kinetic energy
Eg is energy due to gravity
Thus, as the potential energy falls toward earth, Eg will approach 0, which will decrease its amount.

Answer: C. They will have more time to manage his mother's care.
Explanation:
A single income option means that only one of them will be working and only one source of income will be used to maintain all three of them including Daniel's mother. This will most definitely result in them having less disposable income and less financial income in general.
Also the scenario painted made no mention of a baby so option D is incorrect. The most likely option in C which makes sense because with one of them staying home to take care of the mother, they will have time to be able to take care of her better.
