A. Large and pulls objects towards itself
The elastic potential energy stored in the spring is
= (1/2) x (spring constant) x (distance stretched or compressed)²
If all four springs are stretched or compressed the SAME distance
from their equilibria, then the potential energy is just proportional
to the spring constant.
From greatest to least stored energy is exactly the same list as
from greatest to least spring constant:
X . . . . . 35
W . . . . . 24
Y . . . . . 22
Z . . . . . 15
Answer:
I'm not sure what your answer choices are but I would consider it a conductor.
Explanation: Things that conduct anything are conductors.
I hope that this will help, good luck.
Answer:
A sedimentary rock is off of a boulder.
Explanation:
The question is incomplete. The complete question is :
A mass is attached to the end of a spring and set into oscillation on a horizontal frictionless surface by releasing it from a compressed position. The record of time is started when the oscillating mass first passes through the equilibrium position, and the position of the mass at any time is described by x = (4.7 cm)sin[(7.9 rad/s)πt].
Determine the following:
(a) frequency of the motion
(b) period of the motion
(c) amplitude of the motion
(d) first time after t = 0 that the object reaches the position x = 2.6 cm
Solution :
Given equation : x = (4.7 cm)sin[(7.9 rad/s)πt].
Comparing it with the general equation of simple harmonic motion,
x = A sin (ωt + Φ)
A = 4.7 cm
ω = 7.9 π
a). Therefore, frequency,
= 3.95 Hz
b). The period,
= 0.253 seconds
c). Amplitude is A = 4.7 cm
d). We have,
x = A sin (ωt + Φ)
Hence, t = 0.0236 seconds.
