Answer:
10.87 m
Explanation:
Total length of the wire = 25 m
Let the length of one piece is y and other piece is 25 - y
Let the side of square is a.
So, 4 a = y
a = y / 4
And the side of triangle is b
3 b = (25 - y)
b = (25 - y) / 3
Area of square, A1 = side x side =
A1 = y² / 16
Area of equilateral triangle, A2 =
Total area, A = A1 + A2
For maxima and minima, fins dA /dy
It is equal to zero.
9y = 173.2 -6.928 y
15.928 y = 173.2
y = 10.87 m
So, the length of wire to make square is 10.87 m.
Answer:
Explanation:
We are asked to calculate the force you are applying to a car. According to Newton's Second Law of Motion, force is the product of mass and acceleration. Therefore, we can use the following formula to calculate force.
The mass of the car is 2000 kilograms and the acceleration is 0.5 meters per second squared.
Substitute the values into the formula.
Multiply.
Convert the units. 1 kilogram meter per second squared is equal to 1 Newton. Our answer of 100 kilogram meters per second square is equal to 100 Newtons.
You apply <u>100 Newtons</u> of force to the car.
The correct scientific statement is that force get things going and forces also stop the motion of an object.
<h3>What is force?</h3>
Force is an agent which causes a change in the state of rest or motion of an object.
Force can also be described as a pull or push agent.
Applied force will start an object at rest going or stop the motion of a moving object.
Forces may be contact or non-contact forces.
The misconception in the statement is that an object will run of out of energy.
However, an object never runs out of energy because energy is neither created nor destroyed. Also, an object stopping is due to the fact that other forces are acting to stop its motion.
Therefore, the correct statement is that Force get things going and also stop the motion of an object.
In conclusion, the application of force will result in changes ij the state ad motion of objects.

Answer: the velocity of the center of mass of the two block is v.
Explanation:
Hi, to answer this question we have to apply the next formula:
vcm = [ m1v1 + m2v2] / (m1+m2)
Where:
vcm =velocity of the center of mass
m1 = mass 1 , m2 = mass2
v1 = velocity 1; v2= velocity 2
Replacing with the values given:
vcm = ( 2(4v) - 3v) / (2+3) = (8v-3v) /5 = 5v/5 = v
The velocity of the center of mass of the two block is v.

Answer:
Your core stabilizes your body, allowing you to move in any direction as well as having proper balance. It helps prevents falls and supports your body. So having a strong core is beneficial to everyone because it allows your body to function properly. Improved Balance and Stability.
