You have two carts, a force probe connected to a computer, a
motion detector, and an assortment of objects of different masses.
Design three experiments to test whether momentum is a conserved
quantity. Describe carefully what data you will collect and how you
will analyze the data.
1. how would one calculate the temperature of a probe at a
distance X from wall.
Thermal conductivity is known
Diameter is known
Extenernal ambient temperature is known
Surface heat transfer coefficient is known
Gas temperature is known
Radiative heat transfer is negligible
2. How would one calculate rate at which energy is gained by
convection to the probe (using above information)
3. How to determine minimum length of probe to be considered
A solution is made by mixing exactly 500 mL of 0.153 M
NaOH with exactly 500 mL of 0.100 MCH3COOH.
Calculate the equilibrium concentration of the species below.
Ka of CH3COOH is 1.8
A solution is made by mixing exactly 500 mL of 0.149 M NaOH with
exactly 500 mL of 0.100 M CH3COOH. Calculate the equilibrium
concentration of the species below. Ka of CH3COOH is 1.8 X 10-5
[H+], [OH-], [CH3COOH], [Na+], [CH3COO-} enter answer in
A solution is made by mixing exactly 500.0 mL of 0.167 M NaOH
with exactly 500.0 mL of 0.100 M CH3COOH. Calculate the
equilibrium concentrations of H3O+,
CH3COOH, CH3COO-, OH-,
[H3O+] = M
[CH3COOH] = M
[CH3COO-] = M
[OH-] = M
[Na+] = M
Suppose we perform a double-slit
experiment with a detector placed at a position of minimum
intensity (maximum destructive interference), off-center where the
path lengths differ by half a wavelength. The light source is
alternately turned on and off (or blocked and unblocked near the
source) and the intensity over time is recorded. I interpret the
uncertainty principle to mean that there will be a peak in
intensity at the times when the switch is flipped (whether
on-to-off or off-to-on). i.e.,...
