Consider the first major feature (orderly motions). Which of the following correctly describe patterns of motion in our solar sy

snow_lady [41]

Answer:

(a), (c), (e)

Explanation:

(a) The Sun and most of the planets rotate in the same direction that the planets orbit.

The Sun and most of the planets rotates in the same direction (counter-clockwise) as a consequence of the conservation of the angular momentum from the could in which they were formed.

However, Venus and Uranus rotate in retrograde motion (clockwise), it is thought that is due to the collision with an asteroid in the early days of both planets.

(b) Major moons generally have polar orbits, meaning orbits that take them over the north and south poles of the planet they orbit.

Polar orbits are not common between major moons, They follow orbits related to the plane of the Solar System.

(c) Planets have nearly circular orbits.

Kepler's first law establishes:

All the planets revolve around the Sun in an ellipse orbit, with the Sun in one of the focus.

The ellipse has a low eccentricity in the case of planetary orbits.

(d) The outer planets are so large that they nearly collide with each other on each orbit.

They have enough space between them, so it is not possible a collision.

For example, lets take the example of the diameter on Jupiter and Saturn. The diameter of Jupiter is 139.820 Km while Saturn has a diameter of 116.460 Km.

The distance of Saturn from the Sun is 9.5 AU (AU = Astronomical Unit) while in Jupiter is 5.1 AU.

1 AU is defined as the distance between the Earth and the Sun ( $1.50x10^{8} Km$ )

The distance of Saturn from the Sun in Kilometers:

$d_{saturn} = 9.5 AU . \frac{1.50x10^{8} Km}{1AU}$

$d_{saturn} = 1.425x10^{9} Km$

The distance of Jupiter from the Sun in Kilometers:

$d_{saturn} = 5.1 AU . \frac{1.50x10^{8} Km}{1AU}$

$d_{saturn} = 7.65x10^{8} Km$

Distance between the two planets:

$d_{J-S} = 1.425x10^{9} Km -7.65x10^{8} Km$

$d_{J-S} = 6.60x10^{8} Km$

If the distance between the planets is compared with the diameters of any of them, it is easy to see that the planets can't be in a collision since they don't fill the space between them with its diameter.

In the case of Jupiter:

$diameter_{Jupiter}$ $d_{J-S}$

$139.820 Km$ $6.60x10^{8}$

In the case of Saturn:

$diameter_{Saturn}$ $d_{J-S}$

$116.460 Km$ $6.60x10^{8}$

(e)All the planets orbit the Sun in nearly the same plane.

When the cloud, from were the planets form, collapse, it starts to rotate and accrete the material in a disk. Given as a result that the planets were in nearly the same plane.

It is important to consider that planets have different degrees of orbital inclinations, which is due to interactions with others object while its formation.

(f) Inner planets orbit the Sun in the opposite direction from the outer planets

This is not correct. Inner planets are constituted by Mercury, Venus, Earth, and Mars.

Mercury, Earth and Mars share the counter-clockwise direction as some outer planets, while Venus shares the same retrograde motion as Uranus.

A hydraulic lift has two connected pistons with cross-sectional areas 15 cm2 and 670 cm2. It is filled with oil of density 510 k

BigorU [14]

Answer:

Explanation:

Given

Cross-sectional area of two areas is

$A_1=15\ cm^2$

$A_2=670\ cm^2$

It is filled with oil of density $\rho _0=510\ kg/m^3$

mass of car place on Large area $M=1100\ kg$

Suppose a mass of m kg is placed on smaller area

According to pascal law's intensity of pressure is same at every point on Liquid

$P_1=P_2$

$\frac{F_1}{A_1}=\frac{F_2}{A_2}$

$\frac{mg}{15}=\frac{Mg}{670}$

$m=1100\times \frac{15}{670}$

$m=24.62\ kg$

Which phrase describes an atom?

kiruha [24]

You haven't included the list of choices that goes with the question, so it's
impossible for me to choose the correct one, or to help you choose it.

Regarding my ability to answer the question and collect the 5-point bounty,
I'm free to make up any phrase of my own that correctly describes an atom.

-- very very very very very very very tiny

-- includes even tinier particles, with electric charges
both positive and negative

-- smaller than the wavelength of visible light

Define total mechanical energy

zavuch27 [327]

Answer:

The total mechanical energy is the sum of kinetic and potential energies: E = K + U. The law of conservation of total mechanical energy states that the sum of the kinetic energy and potential energy is constant in time.
