B) The amount of work done
The speed of an object in a mass-spring system is given under the function
Here,
m = mass
k = Spring constant
A = Amplitude
x = Position
When the position is at the equilibrium point (x = 0), the speed will be maximum, and could even be expressed as
So the correct answer is B.
If the machine's mechanical advantage is 4.5, that means that
Output force = (4.5) x (Input force) .
We know the input force, and we need to find the output force. Rather than wander around the room looking at the floor while our hair smolders, let's try putting the numbers we know into the equation I wrote up there. OK ?
Output force = (4.5) x (Input force)
Output force = (4.5) x (800 N)
Now dooda multiplication:
<em>Output force = 3,600 N</em> .
That's exactly what the question asked for. So we're done !
Answer:
Amplitude
Explanation:
A wave is a periodic oscillation that carries energy, but not matter, through space or through a medium.
A wave is characterized by the fact that the particles in the medium oscillate around a fixed point, but there is no overall movement of particles in the direction of the wave (this means, only energy is transferred, while matter is not transferred).
A wave is also characterized by several properties, namely:
Amplitude: it is the maximum distance the particles of the medium move from their resting positions
Frequency: the number of oscillations of a certain particle per second
Wavelenght: the distance between two points of the wave that have same shape
Period: the time it takes for one particle of the wave to complete one oscillation
So, the answer is
Amplitude
Answer:
Velocity
Explanation:
You would be describing the velocity of the car.
Velocity in physics is defined as Vector quantity that describes the displacement of an object with respect to the time it takes to attain it. Displacement is the addition of direction to the speed of an object. The displacement is noted in the question, "traveling eastward". While it is stated that the car travels at 44.704 m/s. Ordinarily, it would have been tagged speed, if not for the direction added to it which makes it velocity.
I hope you understand.
