The answer using the graphical method and analytical method of vector addition will always be
C. Same
Analytic method means adding vectors (x₁,y₁) and (x₂,y₂) give (x₁+x₂,y₁+y₂)
Example: Addition of (2,3) and (1,1) gives (3,4)
Solving it graphically will also give (3,4)
(a) The period of the oscillation is 0.8 s.
(b) The frequency of the oscillation is 1.25 Hz.
(c) The angular frequency of the oscillation is 7.885 rad/s.
(d) The amplitude of the oscillation is 3 cm.
(e) The force constant of the spring is 148.1 N/m.
The given parameters:
- <em>Mass of the ball, m = 2.4 kg</em>

From the given graph, we can determine the missing parameters.
The amplitude of the wave is the maximum displacement, A = 3 cm
The period of the oscillation is the time taken to make one complete cycle.
T = 0.8 s

<span>If the forces are acting in exactly opposite directions, they will subtract, and the magnitude of the resultant force is 6 N. This is the minimum resultant force, so that rules out (1). Similarly, if they act in exactly the same direction, they will add, and the resultant force is 18 N. This will be the maximum resultant force. That rules out (3) and (4). Thus, at some angle (between 0 and 180 degrees), you COULD find a resultant force of 15 N.</span>
Given that,
Pressure = 425 Kpa
Pressure in millimeter of mercury = ?
Since, we know that,
1 Kpa = 7.5 millimeter of mercury
425 Kpa = 425 *7.5 millimeter of mercury
425 Kpa = 3187.76 millimeter of mercury.
The pressure of container filled with oxygen is 3187.76 millimeter of mercury.
To solve this problem, we use this formula:
s = rθ
where
s is the arc length or in this case, the distance traveled by a point of a wheel
r is the radius of the circle or the wheel
θ is the subtended angle or the angle of rotation of the wheel
Plugging in the given values and converting degrees to radians
s = 22 *128 (π/180)
s = 49.15 cm
