a. An electric fence, the fence-wire is set to 60 V while the ground
is always 0.0 V. If we can think of the bird and the cow as
resistors in the circuit. Use what you know from this week
and/or last week's lab to explain the response each animal will
have. Explain your reasoning.

Post
b. If you are caught outside in a lightning-storm, it is important to
avoid hiding under trees. Many cattle deaths during lightning
storms occur when the animals are too close to the tree. It has
been frequently seen that a cow standing with its body aligned
radially to the tree is less likely to survive than cows that have
their body tangentially oriented to concentric circles around the
tree. Use what you know from this week and/or last week's lab
to explain why cow A is safer than cow B or C.
