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:
Force that the output plunger applies to the car; F2 = 3888N
Explanation:
For a hydraulic device, the relationship between the force and the area using Pascal's principle is;
F1/A1 = F2/A2
Where;
F1 is force applied to the input piston
F2 is force that the output plunger applies to the car
A1 is Area of input piston
A2 is area of larger piston
We are given;
R2/R1 = 9
So,R2 = 9R1
F1 = 48N
Area of input piston;
A1 = π(R1)²
Area of output piston;
A2 = π(9R1)²
Since, (F1/A1) = (F2/A2)
Thus;
F1/(π(R1)²) = F2/(π(9R1)²)
If we simplify, π(R1)² will cancel out to give;
F1 = F2/9²
Thus;
F2 = 9² x F1
Plugging in 48N for F1, we have;
F2 = 9² x 48
F2 = 81 x 48
F2 = 3888N
Answer:
B, yellow
Explanation:
yellow peas were dominant over the green peas, which were recessive
In order to completely reverse the heating effects of an electric current, the best way to do it is by reversing the flow of it - which is possible by terminating the current itself. This is the best possible method in removing its heat.
