The correct option is SKELETAL SYSTEM.
Calcium is a mineral that is found in many food and the body needs it to maintain strong bones and teeth and to carry out some biochemical reactions in the body. Calcium in the body is stored in bones and teeth; calcium supports the structure and hardness of these body parts.
The tension in the cables as the elevator travel upwards is 1,960 N.
The given parameters:
- Mass of the elevator, m = 200 kg
<h3>Newton's second law of motion;</h3>
Newton's second law of motion states that the force applied to an object is directly proportional to the product of mass and acceleration of the object.
The tension in the cables as the elevator travel upwards is calculated by applying Newton's second law of motion as shown below;
T = ma + mg
where;
- a is the acceleration of the elevator
- g is the acceleration due to gravity
At constant velocity, acceleration is zero (a = 0)
T = m(0) + mg
T = mg
T = 200 x 9.8
T= 1,960 N
Thus, the tension in the cables as the elevator travel upwards is 1,960 N.

Explanation:
It is given that,
For Honda:
Initial velocity, u = 0
Initial position, ![x_i=0](https://tex.z-dn.net/?f=x_i%3D0)
Final position, ![x_f=300\ m](https://tex.z-dn.net/?f=x_f%3D300%5C%20m)
Acceleration, ![a=3\ m/s^2](https://tex.z-dn.net/?f=a%3D3%5C%20m%2Fs%5E2)
Let t is the time taken by Honda. Using second equation of motion as :
![x_f=x_i+ut+\dfrac{1}{2}at^2](https://tex.z-dn.net/?f=x_f%3Dx_i%2But%2B%5Cdfrac%7B1%7D%7B2%7Dat%5E2)
![300=0+0+\dfrac{1}{2}\times 3t^2](https://tex.z-dn.net/?f=300%3D0%2B0%2B%5Cdfrac%7B1%7D%7B2%7D%5Ctimes%203t%5E2)
t = 14.14 seconds
For Porsche’s :
Initial velocity, u = 0
Initial position, ![x_i=0](https://tex.z-dn.net/?f=x_i%3D0)
Final position, ![x_f=400\ m](https://tex.z-dn.net/?f=x_f%3D400%5C%20m)
Acceleration, ![a=3.5\ m/s^2](https://tex.z-dn.net/?f=a%3D3.5%5C%20m%2Fs%5E2)
Let t' is the time taken by Honda. Using second equation of motion as :
![x_f=x_i+ut+\dfrac{1}{2}at'^2](https://tex.z-dn.net/?f=x_f%3Dx_i%2But%2B%5Cdfrac%7B1%7D%7B2%7Dat%27%5E2)
![400=0+0+\dfrac{1}{2}\times 3.5t^2](https://tex.z-dn.net/?f=400%3D0%2B0%2B%5Cdfrac%7B1%7D%7B2%7D%5Ctimes%203.5t%5E2)
t' = 15.11 seconds
Since, the time taken by Honda is less while the time taken by Porsche's is more. So, Honda wins the race by (15.11 - 14.14 = 0.97) seconds. Hence, this is the required solution.
The both contain a nucleus.
