Procedure 1. Arrange the burette and other equipment as shown in Figure 1. Use a 250-ml Erlenmeyer flask for the titration 2. Fill the burette with NaOH solution using a funnel. (Wear goggles and gloves!) Record the concentration (molarity) of the base in the Data Table on the Worksheet. 3. Measure out 100 mL of flat Mountain Dew in a graduated cylinder and transfer it to the 250-ml Erlenmeyer flask. (If you will be using a magnetic stirrer, place a...

Find the liquid pressure at the bottom of a 50m deep container that carries ethyl alcohol. For the following problem, assume a constant temperature. With an initial pressure of 500pa, what is the final pressure inside a container after it undergoes a volume change from 10 m^3 to 2m^3? A 25kg sphere is balanced on top of a table. The sphere covers an area of 10m^2. What is the pressure applied to this table? Draw the electric field lines between...

Note that you will most likely get different numbers for the different parts below. As usual, a good way to handle that is to solve the problem using variables, and only plug in numbers at the end. A solar pond is a pond full of saltwater that acts as a solar energy collector. A key feature of the pond is a salt concentration gradient in the water, with a higher concentration of salt at the bottom. The energy in sunlight...

A child is too scared to go down but climbs to top and lets his toy car roll down the slide instead. Accelerating at 5 m/sec square for 2 sec the toy car flies away across flat level sandbox. Shortest legs of slide are 30 cm tall. How far from bottom of short legs will toy car land ? Thickness of the steel slide surface is not significant.

A U-tube contains liquid of unknown density. An oil of density
770 kg/m³ is poured into one arm of the tube until the oil column
is 13.5 cm high. The oil-air interface is then 4.5 cm above the
liquid level in the other arm of the U-tube. Find the density of
the liquid.

Problem
Given a triangle of integers, we want to find the path that has
the largest sum going from the top to the bottom of the triangle.
The way we go down the triangle is by moving down level by level,
at each level having the choice to either go straight down to the
integer directly below, or the integer below and to the right.
Consider the following triangle:
