An unbanked circular highway curve on level ground makes aturn

tino4ka555 [31]

Answer:

Explanation:

Given

Velocity of traffic $v=60\ mi/hr\approx 26.82\ m/s$

Maximum value of Centripetal force is one-tenth of weight

such that $(F_c)_{max}=\frac{mg}{10}$

to make a safe turn centripetal force with radius of curvature r is given by

$F_c=\frac{mv^2}{r}$

$(F_c)_{max}=\frac{mg}{10}=F_c=\frac{mv^2}{r}$

$\frac{mg}{10}=\frac{mv^2}{r}$

$r=\frac{10v^2}{g}$

$r=\frac{10\times 26.82^2}{9.8}$

$r=733.99\approx 734\ m$

When a phase change of a substance occurs what happens to the temperature of the substance?

Maurinko [17]

<span>C) It does not change. At the point where the phase of a substance changes, there is no temperature change but only the phase change. After this, the temperature then goes up or down depending on the type of phase change occurring. </span>

Jose throws a ball at 92 mi/hr horizontally. If there were NO air resistance, how

Trava [24]

Answer:

It should be 92 mi/h

Explanation:

Because there is no air resistance there is nothing pushing against it to slow it down, so only the initial force and gravity are acting on the ball
