Which of these challenges is unique to the process of designing prostheses as opposed to engineering other technologies?
- Knowing how a material will fail
- Using the engineering process
- Identifying a need for the technology
- Predicting how a technology will interact with human tissue
Answer:
predicting how a tech will interact with human tissue.
Explanation:
thats not really common except for in the medical field.
The challenge that is unique to the process of designing prostheses as opposed to engineering other technologies is Predicting how a technology will interact with human tissue. The correct option is option 4.
What is Prosthetic Design?Prosthesis design is typically undertaken by shaping wax on a plaster replica of the patient's anatomy. Realism is predominantly achieved through the prosthetist's ability to interpret the correct location and physically recreate the anatomical shape and detail.
Prosthetic applications are an example of the intersection of design, technology and science.

d. The animals such as snakes and tortoises are called reptilians. Why?
Answer:
Explanation : Reptiles are cold blooded animals, have scales on their body (instead of hair or fur) and are usually egg laying. (certain viper types and boas give birth to live young). So that is what makes animals reptiles.
Reptiles are cold-blooded creatures that often lay eggs and have scales on their bodies rather than hair or fur. (Some types of vipers and boas give birth to live young).
Due to these reasons animals are reptiles.
What are reptiles?
Air-breathing vertebrates known as reptiles have unique skin consisting of scales, bony plates, or a combination of the two.They comprise of tortoises, turtles, lizards, snakes, and crocodiles.All of them periodically shed their skin's outer covering. The temperature of their environment affects how they function.Reptiles do not maintain a steady internal body temperature, in contrast to birds and mammals. They cannot stay warm on a chilly day without fur or feathers, and they cannot cool themselves on a hot day without sweat glands or the ability to pant. Instead, they shift as needed between the sun and the shade. They stop moving around when the weather becomes colder. Reptiles are cold-blooded due to their slow metabolic rate and heat-seeking habit.
Thus, it can be concluded that animals such as snakes and tortoises are called reptilians.

The Universal Space Agency wants to know the results of your Sim investigation. Write your report to the lead chemist, explaining why drops of liquid water appeared on the outside of the cold, but not the warm, soda can. Use evidence from your investigation in your explanation.
Answer:
due to warm temperature
Explanation:
Explanation:
There is water present in liquid form instead of liquid nitrogen on the outer side of the can because of the temperature present in the surrounding environment. The temperature around the can is little warm which is favourable for the water but not for the liquid nitrogen. The liquid nitrogen present in liquid state when the temperature of the surrounding is too cold. if it is warm, the liquid nitrogen starts boiling and converts into gaseous state so that's why the warmer temperature is responsible for the presence of water not the liquid nitrogen.
Your teacher asks you to prepare 500 mL of a 2.75 molar solution of NaCl for an upcoming
laboratory experiment. Write a step-by-step procedure describing how you would carry out
this task.
To prepare 500 mL of a 2.75 molar solution of NaCl, measure 80.44 g of NaCl, place it in a 500 mL volumetric flask and fill it with water to the mark.
We'll begin by calculating the number of mole of NaCl in the solution
Volume = 500 mL = 500 / 1000 = 0.5 L Molarity = 2.75 MMole of NaCl =?Mole = Molarity x Volume
Mole of NaCl = 2.75 × 0.5
Mole of NaCl = 1.375 mole
Next, we shall determine the mass of 1.375 mole of NaCl.
Mole of NaCl = 1.375 mole Molar mass of NaCl = 23 + 35.5 = 58.5 g/mol Mass of NaCl =?Mass = mole × molar mass
Mass of NaCl = 1.375 × 58.5
Mass of NaCl = 80.44 g
Therefore, to prepare 500 mL of a 2.75 molar solution of NaCl, measure 80.44 g of NaCl, place it in a 500 mL volumetric flask and fill it with water to the mark.

Answer:
1.
a. Diagram A
b. Diagram A should stay still, but Diagram B should move/roll to the left.
__________________________________
2.
a. Diagram A and Diagram B are different because the object kg are different, one is 10kg and the other is 2kg.
b. Diagram B because its smaller making it lighter to move when Diagram A is 5 times larger, which will make it heavier.
__________________________________
3.
a. Diagram A and Diagram B compare because the object both equal 3kg.
b. Diagram A will have a greater acceleration because 80n > 40n

how do you Calculate the molarity of 250 ml of solution in which 2.7 g of MgCl2 are dissolved
Answer:
Molar mass of MgCl2 is 95 g/mol
Mg = 24 g/mol and Cl = 35.5 ×2 = 71 g/mol
moles = mass given/ molar mass
= 2.7/95 = 0.028 mol
volume = 250/1000 = 0.25 dm3 (ml is the same as dm3)
molarity of MgCl2 = moles/volume
= 0.028/0.25
= 0.112 mol/dm3
