Answer:
Here
Explanation:
Some assume our planet's changing distance from the sun causes the change in the seasons. That's logical, but not the case for Earth. Instead, Earth has seasons because our planet's axis of rotation is tilted at an angle of 23.5 degrees relative to our orbital plane, that is, the plane of Earth's orbit around the sun
Answer:
The correct answer is - 10400 years.
Explanation:
Half-life an element is the time required to decay the half amount of the initial amount of the element.
Here, the initial amount n(i) = 100 gm
remained amount n(r) = 25 gm
then n =?
The formula for the calculating initial amount
n(i)=n(r)⋅2^n
n(i)=n(r)⋅2^n
n(i)/n(r) =2^n
puting value,
100/25 = 2^n
2^n = 4
n = 2
so to decay this amount there is two half life cycles involved,
Thus, time = 2*5700
= 10400 years.

Answer:
Water and Ammonia will form Solution.
Explanation:
Solution is a Homogeneous mixture of two or more components. The solute present in the solvent can not be distinguished neither microscopically nor visually. This formation of Homogeneous mixture usually takes place due to greater intermolecular interactions between the Solute and Solvent. Hence, in given scenario we are not given with the amount of components, therefore we can decide on the basis of interactions between the components.
In case of Water and Ammonia there exist a stronger type of intermolecular interactions called as Hydrogen Bond Interactions as in both compounds Hydrogen atoms are attached to more electronegative atoms like Oxygen and Nitrogen. Hence, as Like Dissolves Like, so these two components will form a Solution.
While in second case, Pentane is a non polar compound while Sodium Chloride is an ionic compound with positive Na and negative Cl. So, these two compounds cannot interact with each other, Hence will fail to form a solution and results in the formation of Suspension.
Answer:
B the golgi body and rough/smooth endoplasmic reticulum are able to synthesise vesicles the only difference is that one synthesises vesicles that go from one organelle to another where as the other synthesises vesicles that travel to the outside of the cell.
