At a picnic, why would wrapping a bottle in a wet cloth be a better method of cooling than placing the bottle in a bucket of cold water?

A car is sitting outside in a driveway. Consider the following statement, "If it starts raining, the car will get wet."

a. Is the converse of the statement true? Explain.

For the reciprocating saw shown, graphically determine the location of all the instantaneous centers.

When the officials saw the _______ , unsanitary condition of the apartment, they took custody of the children.

Show that the product of $a$ and $a^{\dagger}$, in that order, is given by Eq. we saw earlier.

In Exercise we saw earlier, what is the speed of the electron as it emerges from the field?

A circular saw blade accelerates from rest to an angular speed of $3620 \mathrm{rpm}$ in $6.30$ revolutions. Is the angular speed of the saw blade after $3.15$ revolutions greater than, less than, or equal to $1810 \mathrm{rpm}$ ? Explain.

Wet atmospheric air at 100 percent relative humidity contains saturated water vapor and, by Dalton’s law of partial pressures,

$$P_{atm} = P_{dry air} + P_{water vapor}$$

Suppose this wet atmosphere is at 40°C and 1 atm. Calculate the density of this 100 percent humid air, and compare it with the density of dry air at the same conditions.

For the reciprocating saw shown, analytically determine the location of all the instantaneous centers.

A clothesline is stretched taut between two poles. Then a wet towel is hung at the center of the line. Can the line remain horizontal? Explain.

A contracting company rents a generator for 6 hours and a heavy-duty saw for 6 hours at a total cost of 48 dollars. For another job the company rents the generator for 4 hours and the saw for 8 hours for a total cost of 40 dollars. Find the hourly rates $g$ (for the generator) and $s$ (for the saw) by solving the system of equations $6 g+6 s=48$ and $4 g+8 s=40$.

In the circuit shown in Fig. we saw earlier find (b) the resistance $R$;

Try each of the confirmations in Exercise we saw earlier, with a circular region as the unit.

Insert commas where necessary. Some sentences may be correct. Yes nonvascular plants grow only where it is wet.
