Applicable Equations: ΣIin = ΣIout of a junction, V = IR, ΣV = 0 in a loop You will get 0.25 points each for providing the correct numerical answers with their respective units in the table.

You will get one point each for properly identifying how to use Kirchhoff’s first law, Kirchhoff’s second law, and Ohm’s law. To get the full 3 points for this section you must do one of the following:

A: Fill in the table with the correct numerical values of potential, current, or resistance that is missing.

Or...

B: If you prefer to answer qualitatively or you are not sure of your algebra you may qualitatively explain how to apply Kirchhoff’s 1st and 2nd laws as well as Ohm’s law.
If you can accurately complete the table you do not have to provide any qualitative explanation.

if the thermos has a vacuum innner, then heat through conv currents and conduction are reduced = vacuum flask

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees. 

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
