What is the correct classification of a mixture in which both a solid and a liquid are visible?
stepan [7]
<span>The answer is a heterogeneous mixture. Mixtures can be homogeneous and heterogeneous. If a solid and a liquid of a mixture cannot be separated and the difference between them is not visible, it is called homogeneous mixture (or solution). If a solid and a liquid of a mixture are visible and can be separated easily, the mixture is called heterogeneous.</span>

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)

Johanna makes the table below to organize her notes about centripetal forces.
umka21 [38]

Gravity

Explanation:

Johanna's table:

       Circular motion                        Centripetal force

       space station in orbit                         X

        a child in a swing

         a ball on a string

The type of centripetal force at work in a space station in orbit is the force of gravity.

The force of gravity is constantly pulling and attractive all objects and bodies to its center.

This force is directed towards the center of the orbit of the earth and it is a centripetal force

  • Gravity attracts any object that has mass.
  • The mass of the satellite and the earth keeps it in orbit and prevents it from moving out of orbit.
  • The more the mass the more the gravitational attraction.

If an element has a charge of 1+, how many more protons does it have than electrons?
Vlada [557]
If an element has a charge of +1, there is 1 more proton than electrons.

A proton has a charge of +1
A neutron has a charge of 0
A electron has a charge of -1.

For there to be a charge of 0, there would be the same amount of charges for both proton and neutron. To get a charge of 1, you will need 1 more proton.

Which forces tend to slow down an object
laila [671]
The answer is "friction and air resistance" gravity does some of the work by keeping the object from floating away, but friction and air resistance does the biggest part. Friction is how rough the ground it meaning on tile, dirt, grass, etc... that would slow down the object and air resistance is the gravity pushing on the object also making it stop. 

Hope this helps!
