Answer:
the mathematical models, Newton's second law, improve the response of our designs and allow us to modify them to be more resistant.
Explanation:
When an object is designed it is done based on some models or guides, specifically Newton's second law is given in the form
∑ F = m a
We can make a design and test with forces applied in several different places and with different intensity, to find weak points in the design, this is done a lot today in the construction of tall buildings, in the design of airplanes; The great advantage of this is that it allows you to see problems without significant cost of money and human lives.
There are also designs that can be modified to improve the response of our system to different external stimuli, this is widely used in the design of bridges, to see the response of the structure before load changes and different climatic conditions.
In summary, the mathematical models, Newton's second law, improve the response of our designs and allow us to modify them to be more resistant.
Answer:
1/3 the distance from the fulcrum
Explanation:
On a balanced seesaw, the torques around the fulcrum calculated on one side and on another side must be equal. This means that:
where
W1 is the weight of the boy
d1 is its distance from the fulcrum
W2 is the weight of his partner
d2 is the distance of the partner from the fulcrum
In this problem, we know that the boy is three times as heavy as his partner, so
If we substitute this into the equation, we find:
and by simplifying:
which means that the boy sits at 1/3 the distance from the fulcrum.
Answer:
A mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium. While waves can move over long distances, the movement of the medium of transmission—the material—is limited. Therefore, the oscillating material does not move far fro
