I think the answer is transparent and translucent
Answer:
sun, air, water, wind and ocean current
Explanation:
As sun is the major source of energy on earth, the earth gets heated due to solar energy, this creates convection currents in the Air and Water, the heating of these areas create wind and ocean currents due to difference in temperature and pressure.
Answer: option <span>D. be given a positive charge produced by the movement of electrons to the other end of the ball.
</span>
Explanation:
This phenomenon is called electrostatic induction.
The excess of negative charge on the end of the rod will repel the electrons on the side of the pith ball that have been approached to it.
Then the electrons on the pith ball will move far away from this end with it will be left an excess of positive charge.
In this way the rod has induced that the ball acquires a positive charge on one end and a negative charge on the other end.

You may find bellow the balanced chemical reactions.
Explanation:
To balance chemicals equation the number of atoms of each element
entering the reaction have to be equal to the number of atoms of each
element leaving the reaction, in order to conserve the mass.
2. Single displacement: Zn + 2 HCl → ZnCl₂ + H₂
3. Decomposition: NiCl₂ → Ni + Cl₂
4. Double displacement: 2 LiI + Pb(NO₃)₂ → PbI₂ + 2 LiNO₃
5. Double displacement: BaCl₂ + H₂SO₄ → BaSO₄ + 2 HCl
6. Single displacement: Cu + 2 AgNO₃ → Cu(NO₃)₂ + 2 Ag
7. Synthesis (combination): 2 Na + O₂ → 2 Na₂O
8. Solid mercury (II) oxide decomposes to form liquid mercury and oxygen.
2 HgO (s) → 2 Hg (l) + O₂ (g) (decomposition reaction)
9. A solution of zinc hydroxide reaction with phosphoric acid (H₃PO₄) to produce solid zinc phosphate and water.
3 Zn(OH)₂ + 2 H₃PO₄ → Zn₃(PO₄)₂ (s) + 6 H₂O (l) (double displacement reaction)
where:
(s) - solid
(l) - liquid

Answer:
25.33125KPa
Explanation:
From the above,
1atm = 101.325KPa
0.25atm = (0.25atm x 101.325KPa) / 1atm = 25.33125KPa
Therefore, 0.25atm = 25.33125KPa
