C) is correct
Have a good day
Pressure = (weight) / (area supporting the weight).
From the fraction, you can see that <em>more weight </em>produces more pressure,
and <em>less area</em> produces more pressure.
So, for the greatest pressure, you want the greatest weight supported by
the smallest area.
That would be the 55-kg boy, standing on one foot.
Answer: Mass is both a property of a physical body and a measure of its resistance to acceleration (rate of change of velocity with respect to time) when a net force is applied. An object's mass also determines the strength of its gravitational attraction to other bodies.
