The orbits of all the planets in the solar system are slightly elliptical with the exception of _______.
aksik [14]

Answer:

There is no exception to this. all planets have some eccentricity. it is physically impossible to have an orbit without any eccentricity. However, venus's orbit has the lowest (0.007) eccentricity (closest to circular) so that could be your answer.

Mercury's orbit's eccentricity 0.2

Venus's orbit's eccentricity 0.007 (this is the lowest so it may be your answer)

Earth's orbit's eccentricity 0.0167

Mars's orbit's eccentricity 0.0934

Jupiter's orbit's eccentricity 0.0489

Saturn's orbit's eccentricity 0.0565

Neptune's orbit's eccentricity 0.009

Uranus's (yur,in,iss) orbit's eccentricity 0.0457

Pluto's (not really a planet) orbit's eccentricity 0.2444 (very high)

hope it helped.

A microphone is attaced to a spring that is suspended from
kirill115 [55]

To solve this problem we will apply the concept related to the amplitude and the Doppler effect. The difference between the maximum and minimum frequency detected by the microphone would be given by the mathematical function

f_{max} - f_{min} = 2 f_s (\frac{v_0}{v})

Here,

f_s= Source Frequency

v_0 = Speed of microphone

v = Speed sound

f_{max} - f_{min} = 2 f_s (\frac{v_0}{v})

Maximum speed of the microphone is

v_0 = f_{max} - f_{min} * \frac{v}{2f_s}

v_0= \frac{2.1Hz*343m/s}{2*440Hz}

v_0= 0.8185 m/s

Now the amplitude is

A = \frac{v_0}{2\pi/T}

Here T means the Period, then

A= \frac{0.8185 * 2.0}{2\pi}

A= 0.2605m

Therefore the amplitude of the simple harmonic motion is 0.2605m

A stationary 15 kg object is located in a table near the surface of the earth. The coefficient of static friction between the su
Marta_Voda [28]

The net force acting on the object perpendicular to the table is

∑ F[perp] = F[normal] - mg = 0

where mg is the weight of the object. Then

F[normal] = mg = (15 kg) (9.8 m/s²) = 147 N

The maximum magnitude of static friction is then

0.40 F[normal] = 58.8 N

which means the applied 40 N force is not enough to make the object start to move. So the object has zero acceleration and does not move.
