Answer:
a.
b.
Explanation:
The frequency of a harmonic oscillator is given by the following formula:
----------------- equation (1)
a.
In order to double the frequency of this oscillator:
ω' = 2ω
m' = ?
Therefore,
using equation (1):
a.
In order to triple the frequency of this oscillator:
ω' = 3ω
m' = ?
Therefore,
using equation (1):
All you have to do is add 600 + 1,400 which = 2,000
So your answer is D) 2,000 J
I hope this helps. :)
I had the same test btw
Answer:
= 3.36 mm
Explanation:
From Ohm's law,
(Voltage = Current * Resistance)
The geometric definition of resistance is
where is the resistivity of the material, and are the length and cross-sectional area, respectively.
Since the wire is assumed to have a circular cross-section, its area is given by
where is the diameter.
Resistivity of copper = . With these and other given values,
Answer:
speed change
Explanation:
this is the case with 2-D kinematics
