A concrete highway is built of slabs 12 m long .How wide should be the expansion cracks between the slabs at 15 Celsius to preve

morpeh [17]

Answer:

$x=4.2\ mm$

Explanation:

Given:

length of the concrete slab, $l=12\ m$

temperature of observation, $T_o=15^{\circ}C$

we've the coefficient of linear expansion for concrete, $\alpha=10^{-5}\ ^{\circ}C^{-1}$

lower temperature limit, $T_l=-30^{\circ}C$

upper temperature limit, $T_u=50^{\circ}C$

<u>Change in length due to temperature can be given as:</u>

$\Delta l=l.\alpha.(T_u-T_l)$

$\Delta l=12\times 10^{-5}\times (50-(-30))$

$\Delta l=0.0096\ m=9.6\ mm$

<u>Now at temperature 15°C:</u>

$\Delta l'=12\times 10^{-5}\times (15-(-30))$

$\Delta l'=0.0054\ m=5.4\ mm$

Hence the expansion crack between the slabs at this temperature must be:

$x=\Delta l-\Delta l'$

$x=9.6-5.4$

$x=4.2\ mm$

Metals are usually more dense than wood. Pick the statement below which accurately compares metals to wood. Metals have less mas

laila [671]

Answer:

Metals have more mass per unit of volume than wood.

Explanation:

Density is defined as the amount of matter contained in a unit of volume. A material that is denser than another will therefore have more mass per unit of volume.

The density of a body can affect buoyancy, bodies with low enough densities can float in fluids. For example wood can float in water while metals can't.

A 1.0-kg cue ball traveling at 15 m/s strikes a stationary billiard ball of mass 1.5 kg. After the collision, the cue ball remai

Igoryamba

Answer:

Other ball's velocity is 10 m/s

Explanation:

We can use conservation of momentum:

$P_{1i} +P_{2i} =P_{1i} +P_{2i}\\1 * 15 + 1.5 * 0 = 1 * 0 + 1.5 * v\\15 = 1.5 * v\\v=\frac{15}{1.5} \,\frac{m}{s} \\v=10 \,\frac{m}{s}$
