True or False questions. Determine whether or not each of the following statements is true. If a statement is true, prove it. If the statement is false, provide a counterexample and explain how it constitutes a counterexample. Diagrams can be useful in explaining such things.
1. A sphere of radius R is centered at the origin. A total charge Q is uniformly distributed throughout its interior. A ball of radius R/2 centered at the the origin is carved out and discarded, leaving behind an empty cavity. The electric potential has the same value at every point inside the cavity.
2. A sphere of radius R is centered at the origin. A total charge Q uniformly distributed throughout its interior. A ball of radius R/2 centered at the point (x,y,z) = (0, 0,R/4) is carved out and discarded, leaving behind an empty cavity. The electric potential has the same value at every point inside the cavity.

True or False questions. Determine whether or not each of the
following statements is true. If a statement is true, prove it. If
the statement is false, provide a counterexample and explain how it
constitutes a counterexample. Diagrams can be useful in explaining
such things.
a) If the electric potential in a certain region of space is
constant, then the charge enclosed by any closed surface completely
contained within that region is zero.
b) A sphere of radius R is...

True or false:
For each of the statements, determine whether it is true or
false, then explain in a few sentences why that is the answer.
Note: no marks will be given for answers that do not include an
explanation.
1. If money stops being a reliable store of value, then it
ceases to be useful as a medium of exchange.

Determine whether each of the following statements is true or
false. If the statement is false, modify and rewrite it so that it
is a true statement.
a. When a molecule has two, degenerate, “infrared active”,
vibrational modes, the two vibrational modes will show absorptions
at different frequencies in the infrared spectrum.
b. For a given substance, strong intermolecular forces between
molecules of the substance can cause peak broadening of some of the
absorptions in the infrared spectrum of the...

PROBLEM #1:TRUE of FALSE
For each of the following statements, determine whether it is
true or false. Label “T” if it is true, otherwise label “F”.
1-a. If two distributions have the same moment-generating
function, then they are identical at almost all points. For a
random variable X, if its moments of order k (k > 0) exist, then
its moment generating function is continuously differentiable up to
order k.

Determine whether each of the following statements is
True or False. If True, write a proof. If False, exhibit a
counterexample.
1) If m, n are arbitrary positive integers, then any
system of form
x ≡ a (mod m)
x ≡ b (mod n)

For each of the following statements, determine whether the
statement is true or false. If you say the statement is true,
explain why and if you say it is false, give an example to
illustrate.
(a) If {u, v} is a linearly independent set in a vector space V,
then the set {2u + 3v, u + v} is also a linear set independent of
