Answer: I.asteroids II.comets III.meteoroids IV.planets

All of the above

Explanation:

Solar system is family of Sun. The planets an other celestial bodies, orbit around the Sun in elliptical orbit with Sun at one of the foci.

Solar system has 8 planets, asteroids that lie between orbits of Mars and Jupiter in asteroid belt, comets lie in Kuiper belt and Oort clouds and meteoroids that that is the debris of planets and comets.

All these objects orbit the Sun.

Which of the following is a galvanic cell?
sladkih [1.3K]

C. Aluminum (Al) oxidized, zinc (Zn) reduced

<h3>Further explanation</h3>

Given

Metals that undergo oxidation and reduction

Required

A galvanic cell

Solution

The condition for voltaic cells is that they can react spontaneously, indicated by a positive cell potential.

\large {\boxed {\bold {E ^ ocell = E ^ ocatode -E ^ oanode}}}

or:  

E ° cell = E ° reduction-E ° oxidation  

For the reaction to occur spontaneously (so that it E cell is positive), the  E° anode must be less than the E°cathode

If we look at the voltaic series:

<em>Li-K-Ba-Ca-Na-Mg-Al-Mn- (H2O) -Zn-Cr-Fe-Cd-Co-Ni-Sn-Pb- (H) -Cu-Hg-Ag-Pt-Au </em>

The standard potential value(E°) from left to right in the voltaic series will be greater, so that the metal undergoing an oxidation reaction (acting as an anode) must be located to the left of the reduced metal (as a cathode)

<em />

From the available answer choices, oxidized Al (anode) and reduced Zn (cathode) are voltaic/galvanic cells.

The amount of force needed to keep a 10 kg box moving at a constant
boyakko [2]

Answer:

ON

Explanation:

Frictional force is a force that opposes the motion of body. It is because of friction that motion can be controlled and even walking is made possible.

Now, on a frictionless surface, there is no opposition to motion. Therefore, to keep the body moving there is no force required.

  • If surface lacks friction, motion will continue perpetually without any hinderance.

Can someone help me please? I’d appreciate it! Also please do not send me a link or delete your answer! Thanks
chubhunter [2.5K]

Answer:

14.53ML

Explanation:

V1=218

V2=?

P2=15p1

USING BOYLE'S LAW

P1V1=P2V2

V2=P1V1/P2=P1(218ML)/15P1

=14.53ML
