Example ______ 1. Did president Carter veto the bill?

______ We are honored to accommodate you, senator Hall.

The magnitudes of the electric and magnetic fields in a velocity selector are $1.8 \times 10 ^ { 5 } \mathrm { V } / \mathrm { m }$ and 0.080 T, respectively. (a) What speed must a proton have to pass through the selector? (b) Also calculate the speeds required for an alpha-particle and a singly ionized $^ { s } O ^ { 16 }$ atom to pass through the selector.

Differentiate between endocrine and exocrine glands.

According to Einstein's special theory of relativity, the mass of a moving particle, $m_{\text {moving }}$, is related to its mass at rest, $m_{\text {rest }}$, by the equation

$$m_{\text {moving }}=\frac{m_{\text {rest }}}{\sqrt{1-\left(\frac{u}{c}\right)^2}}$$

where $u$ and $c$ are the speeds of the particle and light, respectively.
(a) In particle accelerators, protons, electrons, and other charged particles are often accelerated to speeds close to the speed of light. Calculate the wavelength (in $\mathrm{nm}$ ) of a proton moving at $50.0$ percent the speed of light. The mass of a proton is $1.673 \times 10^{-27} \mathrm{~kg}$.
(b) Calculate the mass of a $6.0 \times 10^{-2} \mathrm{~kg}$ tennis ball moving at $63 \mathrm{~m} / \mathrm{s}$. Comment on your results.

A proton in a synchrotron is moving in a circle of radius 1 km and increasing its speed by

$$v(t) = c_1 + c_2t^2,$$

where

$$c_1 = 2.0 × 10^5 m/s, c_2 = 10^5 m/s^3.$$

(a) What is the proton's total acceleration at t = 5.0 s? (b) At what time does the expression for the velocity become unphysical?

The fate of an antiproton is usually annihilation via the reaction $p+\bar{p} \rightarrow \gamma+\gamma$. Assume that the proton and antiproton annihilate at rest. (a) Why must there be two photons rather than just one? (b) What is the energy of each photon? $(c)$ What is the wavelength of each photon? $(d)$ What is the frequency of each photon?

What is the difference between rough ER and smooth ER?

Contrast exocrine glands with endocrine glands.

Distinguish between exocrine glands and endocrine glands .

Make a rough sketch of the graph of each function.
$y=-\ln x$

Both brass and bronze contain copper. Describe the difference between these two alloys.

Is the following sentence true or false? The pancreas is both an endocrine gland and an exocrine gland. ______________________

GENERAL: GENERAL: Body Temperature If a person's temperature after x hours of strenuous exercise is $T(x)=x^3\left(4-x^2\right)+98.6$ degrees Fahrenheit (for $0 \leq x \leq 2$ ).

a. Graph the temperature function T(x) given in Exercise 67 on the window [0, 2] by $[90,110]$. TRACE along the temperature curve to see how the temperature rises and then falls as time increases.

b. Find the rate of change of the temperature after 1 hour. To check your answer to Exercise 67, use the "dy/dx" or SLOPE feature of your calculator to find the slope (rate of change) of the curve at x=1.

c. TRACE along the temperature curve to estimate the maximum temperature.
