A mass of 200 kg is kept on the ground. If it covers an area of 1200cm². Calculate the pressure exterted by it. The depth of water in a pond in 5cm. Calculate the pressure exerted by water at the bottom of the pond. (density of water =1000kg/m³.

The pressure exerted by a cubical box of mass 50 kg and side 50 cm is equal to the liquid pressure in a vessel. If the density of liquid is 100kg/m³ , find the height of liquid. ​

Joan writes four numbers on the board in standard form, and then she writes their scientific notation

Which statement best describes the flow of energy in this scenario

Achemistry student needs to standardize a fresh solution of sodium hydroxide. he carefully weighs out of oxalic acid , a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in of distilled water. the student then titrates the oxalic acid solution with his sodium hydroxide solution. when the titration reaches the equivalence point, the student finds he has used of sodium hydroxide solution.calculate the molarity of the student's sodium hydroxide solution. be sure your answer has the correct number of significant digits.
