what is the question please?
The fact that all phones are slightly different but achieve same primary goal tells us about technology that there can be many different design solutions to address a single problem (option D).
<h3>What is technology?</h3>
Technology is the organization and application of knowledge for practical purposes.
According to this question, many different companies have produced cell phones through technological applications. Although all of the phones are slightly different, they all achieve the same primary goal.
This shows us an intriguing aspect of technology that there can be many different design solutions to address a single problem.

The sugar cube experiment in the laboratory gives us a good approximation of the amount of energy that can be derived from the sugar cube because the amount of energy is neither created or destroyed, it is just converted to another form. If the energy from the sugar cube is converted to other form in the lab then, it is possible that same amount of energy will be derived.
Answer:
Explanation:
Radius = 9.5 x 10⁻² m
area of circle = 3.14 x (9.5 x 10⁻² )²
A = 283.38 x 10⁻⁴ m²
magnetic moment = area x current
M = 283.38 x 10⁻⁴ x 5
= 1416.9 x 10⁻⁴ Am²
Torque = MBsinθ
M is magnetic moment , B is magnetic field .
Max torque = 1416.9 x 10⁻⁴ x 3.4 x 10⁻³ , for θ = 90
= 4817.46 x 10⁻⁷
= 481.7 x 10⁻⁶
= 481.7 μ J
Energy = - MBcosθ
Max energy when θ = 180
MB = 4817.46 x 10⁻⁷ J
Min energy = - 4817.46 x 10⁻⁷ for θ = 0
