Calculating Pressure Exerted by a Tourist on Snow
<p>The pressure \( P \) can be calculated using the relation:</p>
\[ P = \frac{F}{A} \]
<p>where:</p>
<p>\( F \) is the force exerted by the tourist, and</p>
<p>\( A \) is the total contact area of the snow-shoes with the snow.</p>
<p>The force exerted by the tourist due to gravity (weight) is:</p>
\[ F = m \cdot g \]
<p>The mass \( m \) of the tourist is given as 60 kg, and gravitational force \( g \) is 10 N/kg, so:</p>
\[ F = 60 \text{ kg} \cdot 10 \text{ N/kg} = 600 \text{ N} \]
<p>The total area \( A \) is given as 0.6 m².</p>
<p>Now we can calculate the pressure \( P \):</p>
\[ P = \frac{600 \text{ N}}{0.6 \text{ m}^2} = 1000 \text{ Pa} \]
<p>So, the correct answer is:</p>
<p>\( \boxed{D. 1000 \text{ Pa}} \)</p>
