If the ordered pairs (1, 4) and (1, 3) are part of the given relation, then the appropriate choice is ...
... a. (1, 4) and (1, 3), because they have the same x-value
m₁ = mass hanged initially = 0.2 kg
x₁ = initial stretch in the spring = 8 cm = 0.08 m
k = spring constant of the spring
the weight of the mass hanged is balanced by the spring force by the spring hence
Spring force = weight of mass hanged
k x₁ = m₁ g
k (0.08) = (0.2) (9.8)
k = 24.5 N/m
m₂ = mass hanged later = 0.5 kg
x₂ = final stretch in the spring = ?
k = spring constant of the spring = 24.5 N/m
the weight of the mass hanged is balanced by the spring force by the spring hence
Spring force = weight of mass hanged
k x₂ = m₂ g
(24.5) x₂ = (0.5) (9.8)
x₂ = 0.2 m = 20 cm
Answer:
The coordinates of D are -1,0
Step-by-step explanation:
I believe
A parabola is a curve where any point is at an equal distance from:
<span><span>a fixed point (the focus ), and </span><span>a fixed straight line (the directrix )</span></span>
The curve is defined by: <span>y</span><span>2</span><span> = 4ax.</span>
