Given :
The focal length of a concave mirror is 18 cm.
To Find :
The radius of curvature of the concave mirror.
Solution :
We know,
Therefore, the radius of curvature of concave mirror is 36 cm.
Hence, this is the required solution.
Answer:
B
Explanation:
Depends Mostly on bonds electrolysis can be used, chemical bonding like additional of water or by heating back to their elements.
Answer:
This would be traveling at the lower reaches.
Explanation:
A river would be traveling the fastest at the upper reaches and it becomes slower at the middle reaches and the slowest at the lower reaches. A place where water flows fast in a river is where the width is narrow and the bottom is steep. (This is just examples incase you would like to keep notes).
The temperature where vapour pressure equals atmospheric pressure is called BOILING POINT. This vapour pressure increases with rise in temperature. Also boiling point is different for different liquids. Hope I cleared your doubt...
The circular lines you see on the chart are isobars, which join areas of the same barometric pressure.
