The _______ is called the blind spot.

The pectoral girdle consists of the: a. clavicle and sternum, b. sternum and scapula, c. clavicle and scapula, d. clavicle and coccyx.

What particles are found in the nucleus of an atom ?

A nucleus that captures a stray neutron must bring the neutron to a stop within the diameter of the nucleus by means of the strong force. That force, which "glues" the nucleus together, is approximately zero outside the nucleus. Suppose that a stray neutron with an initial speed of $1.8 \times 10^7 \mathrm{~m} / \mathrm{s}$ is just barely captured by a nucleus with diameter $d=1.0 \times 10^{-1+} \mathrm{m}$. Assuming the strong force on the neutron is constant, find the magnitude of that force. The neutron's mass is $1.67 \times 10^{27} \mathrm{~kg}$.

Why do markets fail?

Suppose that $\lim\limits_{x\to 3} f(x)=7$. Are the statements true or false? If a statement is true, explain how you know. If a statement is false, give a counterexample.

$$\lim\limits_{x\to 3}\big(xf(x)\big) = 21$$

How many neutrons are in the nucleus of this isotope?

In this exercise, a statement $S_n$ about the positive integers is given. Write statements $S_1, S_2$, and $S_3$, and show that each of these statements is true.

$S_n:2$ is a factor of $n^2-n$.

How do markets "talk" ?

Two charges A and B are fixed in place, at different distances from a certain spot. At this spot the potentials due to the two charges are equal. Charge A is 0.18 m from the spot, while charge B is 0.43 m from it. Find the ratio

$$q _ { \mathrm { B } } / q _ { \mathrm { A } }$$

of the charges.
