Answer:
False
Explanation:
When the location of the poles changes in the z-plane, the natural or resonant frequency (ω₀) changes which in turn changes the damped frequency (ωd) of the system.
As the poles of a 2nd-order discrete-time system moves away from the origin then natural frequency (ω₀) increases, which in turn increases damped oscillation frequency (ωd) of the system.
ωd = ω₀√(1 - ζ)
Where ζ is called damping ratio.
For small value of ζ
ωd ≈ ω₀
I assume that the force of 20 N is applied along the direction of motion and was applied for the whole 6 meters, the formula of work is this; Work = force * distance * cosθ where θ is zero degrees. Plugging in the data to the formula; Work = 20 N * 6 m * cos 0º.
Work = 20 N * 6 m * 1
Work = 120 Nm
Work = 120 joules
Hope this helps!
Answer:

measures : the distance east or west of the Prime Meridian
Answer: 1- A diagram showing the forces acting on the object.
2- The force vector describes a specific amount of force and its direction. You need both value and direction to have a vector.
3- A vector quantity has a direction and a magnitude, while a scalar has only a magnitude. You can tell if a quantity is a vector by whether or not it has a direction associated with it.
4- I don’t know
5- When two forces acting on an object are equal in size but act in opposite directions, we say that they are balanced forces
6- By applying an unbalanced force, you can change the motion of an object. Unbalanced forces can make an object at rest start moving, make a moving object stop, or change the direction and speed of the object.
7- If the forces on an object are unbalanced, this is what happens: a stationary object starts to move in the direction of the resultant force.
8- Imbalance or unequal force
9- The result is no motion. Balanced forces can cancel each other out. Any time there is a balanced force, the object does not move.
10- net force is the vector sum of all the forces that act upon an object.
