The four inner plants have shorter orbits slower spin ,no rings ,and they are made up of rock and metal
The outer plants are made up of hydrogen and helium, so they are called gas giants

Answer:

A = 6.9 cm

Explanation:

Simple Harmonic Motion

A mass-spring system is a common example of a simple harmonic motion device since it keeps oscillating when the spring is stretched back and forth.

If a mass m is attached to a spring of constant k and they are set to oscillate, the angular frequency of the motion is

$\displaystyle w=\sqrt{\frac{k}{m}}$

The equation for the motion of the object is written as a sinusoid:

$\displaystyle X=A\ cos\ w\ t$

Where A is the amplitude.

The instantaneous speed is computed as the derivative of the distance

$\displaystyle X'=V=-A\ w\ sin\ w\ t$

And the maximum speed is

$\displaystyle V_{max}= A\ w$

Solving for the amplitude

$\displaystyle A= \frac{V_{max}}{w}$

Computing w

$\displaystyle w =\sqrt{\frac{120}{0.2}}=24.5\ rad/ s$

Calculating A

$\displaystyle A=\frac{1.7}{24.5}=0.069\ m$

$\displaystyle \boxed{A=6.9\ cm}$

Two cars are raised to the same elevation on service- station lifts. If one car is twice as massive as the other, how do their p

Brums [2.3K]

Answer:

The potential energy of the more massive one is twice that of the other.

Explanation:

Potential energy is given by

PE = mgh

where m = mass of body, g = acceleration of gravity and h = height or elevation.

For the less massive car, let the mass be $m_1$ . Then its PE is

$PE_1 = m_1gh$

For the massive car, let the mass be $m_2$ . Its PE is

$PE_2 = m_2gh$

But $m_2 =2m_1$

$\therefore PE_2 = 2m_1gh = 2(m_1gh) = 2PE_1$

Hence, the potential energy of the more massive one is twice that of the other.
