Each set of expressions represents the lengths of the sides of a triangle. Find the range of possible values of n. 2n, 5, 7

(a) In air at $0^{\circ} \mathrm{C},$ a 1.60-kg copper block at $0^{\circ} \mathrm{C}$ is set sliding at 2.50 m/s over a sheet of ice at $0^{\circ} \mathrm{C}.$ Friction brings the block to rest. Find the mass of the ice that melts. (b) As the block slows down, identify its energy input Q, its change in internal energy $\Delta E_{\text {int}},$ and the change in mechanical energy for the block-ice system. (c) For the ice as a system, identify its energy input Q and its change in internal energy $\Delta E_{\text {int}}.$ (d) A 1.60-kg block of ice at $0^{\circ} \mathrm{C}$ is set sliding at 2.50 m/s over a sheet of copper at $0^{\circ} \mathrm{C}.$ Friction brings the block to rest. Find the mass of the ice that melts. (e) Evaluate Q and $\Delta E_{\text {int}}$ for the block of ice as a system and $\Delta E_{\text {mech}}$ for the block-ice system. (f) Evaluate Q and $\Delta E_{\text {int}}$ for the metal sheet as a system. (g) A thin, 1.60-kg slab of copper at $20^{\circ} \mathrm{C}$ is set sliding at 2.50 m/s over an identical stationary slab at the same temperature. Friction quickly stops the motion. Assuming no energy is transferred to the environment by heat, find the change in temperature of both objects. (h) Evaluate Q and $\Delta E_{\text {int}}$ for the sliding slab and $\Delta E_{\text{mech}}$ for the two-slab system. (i) Evaluate Q and $\Delta E_{\text {int}}$ for the stationary slab.

Suppose the numbers a, b, and c form a Pythagorean triple. Is each of the following also a Pythagorean triple? Explain. $\sqrt{a}, \sqrt{b}, \sqrt{c}$

The mean free path $\ell$ of a molecule is the average distance that a molecule travels before colliding with another molecule. It is given by $\ell=\frac{1}{\sqrt{2} \pi d^{2} N_{V}}$ where d is the diameter of the molecule and $N_{V}$ is the number of molecules per unit volume. The number of collisions that a molecule makes with other molecules per unit time, or collision frequency f, is given by $f=\frac{v_{\mathrm{avg}}}{\ell}$ (a) If the diameter of an oxygen molecule is $2.00 \times 10^{-10}\ \mathrm{m},$ find the mean free path of the molecules in a scuba tank that has a volume of 12.0 L and is filled with oxygen at a gauge pressure of 100 atm at a temperature of $25.0^{\circ} \mathrm{C}.$ (b) What is the average time interval between molecular collisions for a molecule of this gas?
